Searching the Web for background information on the ExxonMobil SCANfining process, I ran across the following …
“Evolution Of Process Technology For FCC Naphtha Desulfurization: 1997 – 2003; An Example Of Technical Progress Induced By Environmental Regulation,” a report prepared by MathPro Inc। (http://www.mathproinc.com/) 2003.
I find it helpful for the insights it provides in the development of desulfurization technologies from the pilot stage to the commercial stage. In Table 1, for example, CDTech's CD Hydro, Exxon's SCANfining, IFP's Prime G and Mobil's OCTGAIN 125 are listed as "demonstrated" technologies, whereas CDTech's CD Hydro / CD HDS, Mobil's OCTGAIN 220, and UOP's ISAL are listed as "near-commercial" and Black & Veatch's IRVAD and Philips Petroleum's S Zorb G processes are listed as "developing."

The Rat’s Maze of Copyright
Ever since the case of American Geophysical Union v. Texaco, Inc., 37 F.3d 881 (2nd Cir. 1994), corporate legal has been careful that their company does not become liable for copyright infringement, unintentional though it may be.
To get a taste of the complexities of copyright, take a look at Professional Fair Use after Texaco (http://www.utsystem.edu/OGC/IntellectualProperty/tex2.htm)
Here are a couple of excerpts …
“All professionals in the university community should be aware of an important case that may potentially affect the way we pursue scholarship and research. On October 28, 1994, the Second Circuit Court of Appeals affirmed the decision of New York's Southern District Court that Texaco's copying of journal articles by or for its scientists was an infringement of the copyright owners' exclusive rights … The court indicated that to the extent the Copyright Clearance Center provided Texaco various convenient and reasonably priced mechanisms for payment of fees for copying, the scope of fair use had been reduced … The case gives copyright owners a tremendous incentive to register with the Copyright Clearance Center or other such licensing entity”
During my tenure as a librarian for Aramco Services (Saudi Aramco), I administered a number of contracts for information products. All of them included provisions for copyright. All of them were different. Some contracts made it possible for anyone in the entire Saudi Aramco enterprise to access the product. Other contracts went to the other extreme, allowing only a handful of specific individuals access to the product. And then there was a whole range in between the two extremes.
Before you share articles you find when you search a product, consult with your corporate librarian, if there is one, to find out what is permissible under the contract. If your company does not employ a librarian, find out who in your company administers the contract for the product . If all else fails, contact the sales rep for the product.
You might also ask if the company maintains an agreement with the CCC - Copyright Clearance Center (http://www.copyright.com/)

Hart Energy
Hart Energy (http://www.hartenergy.com/home.हटमल) publishes a number of highly targeted newsletters and magazines, such as Diesel Fuel News. ULSD – Ultra Low Sulfur Diesel – is a major focus of refiners these days, as increasingly stringent regulations begin to be implemented. A quick search on “desulfurization” produced the following article, among others.
Topsoe: Improved Catalyst Dispersion Cuts ULSD Hydrotreating Cost
--------------------------------------------------------------------------------
San Antonio, Texas – Haldor Topsøe first introduced “Brim” catalysts for ultra-low sulfur diesel (ULSD) hydrotreating five years ago – and with great success, judging by the “several hundred hydrotreaters” using this catalyst.
But the drive to cut costs for ULSD continues, which explains the latest generation “Brim” with improved catalyst dispersion on the carrier surface, as Topsøe distillate marketing manager Lars Skyum explained in a presentation to National Petrochemical & Refiners Association 2009 annual meeting here late last month.
“With this new technology Topsøe now offers both catalysts with the same activity as the first generation but at lower fill cost, as well as more active catalyst types,” Skyum said.

Energy and Environment
SRI's Assisted Hydrothermal Oxidation (AHO) technology is used by Mitsubishi Heavy Industries in Japan to safely dispose of polychlorinated biphenyls (PCBs) from wastewater.
As the lifeblood of all industrial and technological societies, energy is one of our most fundamental needs. Our nation's goal to achieve energy self-sufficiency affects U.S. foreign, environmental, security, and economic policies. Developing new energy sources and exploiting existing ones more efficiently and cleanly are among the 21st century's greatest challenges.
SRI addresses this issue with a diversified, holistic approach that brings multiple disciplines together to work on a problem of staggering technological, economic, and political complexity. Our government and commercial clients worldwide benefit from our scientific expertise and practical know-how in a range of areas, from basic and applied research to developing and testing of advanced systems.
In the 1940s, SRI pioneered smog research in Los Angeles and hosted the first National Air Pollution Symposium. In the 1970s, our groundbreaking research into the environmental causes of lung diseases led to regulatory guidelines for air pollutants. In the 1980s, we demonstrated how chlorofluorocarbons (CFCs) contribute to the ozone hole, and developed protocols for the EPA’s regulation of pesticides.

Trace Metal Capture Preparation and Characterization of Catalysts and Sorbents
PSDF Transport Gasifier Laboratory-Scale Gasifer
Desulfurization, Tar Cracking, Ammonia Cracking
Desulfurization
This table summarizes results of recent tar cracking tests at PSDF using various catalysts and operating temperatures.
Southern Research's experience in hot-gas desulfurization includes the evaluation of commercial and custom-developed sorbents based on zinc and iron formulations in the temperature range of 550 to 750°F. One of the commercial sorbents (Johnson-Matthey Puraspec) was used to achieve H2S levels in the ppb range for a slipstream evaluation of a fuel cell. We have also worked closely with DOE on the optimization of the RVS-1 and RVSLT-1 sorbents developed by DOE.
Tar and Ammonia Cracking
Southern Research's experience includes high-temperature cracking of tar and ammonia at 1650 to 1750°F using nickel-based catalysts and lower-temperature tar cracking at 800°F using modified FCC catalysts. A process for the destruction of ammonia is also being developed based on the use of "Reverse" Selective Catalytic Reduction at 700-800°F. In this process, nitrogen oxides are injected or generated in situ to react with the ammonia and convert it to nitrogen.
The table below shows target conversions of ammonia and tar-related compounds. Experimental conversions achieved at the Power Systems Development Facility are shown under the target conversions.

Research in Action: Trans Ionics Corporation
Trans Ionics Corporation (http://www.transionics.com/) looks to be an enterprise worth a second look. I ran across the name in an article called “Top-10 Most Promising ‘Clean Tech’ Companies Revealed" (http://www.hartfuel.com/1108/f.top10cleantech.html) which led me to The Rice Alliance for Technology and Entrepreneurship (http://www.alliance.rice.edu/alliance/). The Rice Alliance sponsors The Rice Alliance Technology Venture Forums, which, according to its site, “are some of the largest technology venture forums in North America. Representatives from emerging technology companies showcase their new ventures in front of investors and venture capitalists, industry representatives, business leaders, advisors, mentors, service providers and entrepreneurs. The Rice Alliance holds four Technology Venture Forums a year – one each in energy/clean tech, information technology/Web 2.0, nanotechnology, and life science.”
I followed a link to a “company directory” (http://www.alliance.rice.edu/alliance/Company_Directory.asp?SnID=2) which included a description of the company …
“Trans Ionics Corp. —Trans Ionics is developing a desulfurization process that removes sulfur from petroleum streams, including diesel fuel, to meet government mandated diesel sulfur specifications for fueling on and off-road diesel-powered vehicles.”
A patent search on Trans Ionics produced the following recent patent:
Title:

Free the Patents
A pretty silly title, really. Patents are already free at the USPTO site. However, there are advantages to searching a site like FreePatentsOnline (http://www.freepatentsonline.com/). One advantage is the sheer speed of the search engine. When I searched the site for recent ChevronMobil patents containing the key words DESULFURIZATION or DIBENZOTHIOPHENE, it took me longer to type in the search statement (below) than it took the search engine to return the results (reproduced below).

Patent Searching on the Wild Side
Practice makes perfect, as they say, and nowhere is that more a propos than in searching for patents Here’s a quick example …
Let’s pretend that we are interested in all the patents for which ExxonMobil is the assignee (i.e., the owner).
Searching the USPTO database (http://patft.uspto.gov/) using the search phrase AN/ExxonMobil results in 1760 hits.
Searching the USPTO database using the search phrase AN/Exxon results in 6449 hits.
Searching the USPTO using the search phrase AN/Exxon$ (where “$” is a wildcard) results in 8224 hits.
You’ll notice that the wild card (“$”) enables us to retrieve patents issued where Exxon is the assignee OR where ExxonMobil is the assignee. And you will also notice that the whole is greater than the sum of the parts. Add 1760 + 6449 = 8209. Yet, the final wild card search strategy retrieves 8244.
Time for a walk on the wild side.

Classy Patents
Perseverance in patent searching pays off in the long run. One tactic is to begin the search with a key word like “dibenzothiophene.” Explore the results of the search for patents of interest, and then do another search by the primary classification number(s) assigned to those patents. The result will be a list of patents that may also be of interest, even though they may or may not contain the key word of your initial search.
Example …
A search on the USPTO patent database (http://patft.uspto.gov/) using for patents issued in 2008 containing the keyword “dibenzothiophene” (SPEC/dibenzothiophene AND ISD/1/$/2008) results in seven hits, listed below.

United States Patent 7,318,845 (January 15, 2008)
Compact distillates fuel processor with effective sulfur removal process
Abstract
A distillate fuel steam reformer system in which a fuel feed stream is first separated into two process streams: an aliphatics-rich, sulfur-depleted gas stream, and an aromatics- and sulfur-rich liquid residue stream. The aliphatics-rich gas stream is desulfurized, mixed with steam, and converted in a reforming reactor to a hydrogen-rich product stream. The aromatics-rich residue stream is mixed with air and combusted to provide heat necessary for endothermic process operations. Reducing the amounts of sulfur and aromatic hydrocarbons directed to desulfurzation and reforming operations minimizes the size and weight of the overall apparatus. The process of the invention is well suited to the use of microchannel apparatuses for heat exchangers, reactors, and other system components, which may be assembled in slab configuration, further reducing system size and weight.

The aromatics-rich residue stream is mixed with air and combusted to provide heat necessary for endothermic process operations. Reducing the amounts of sulfur and aromatic hydrocarbons directed to desulfurzation and reforming operations minimizes the size and weight of the overall apparatus. The process of the invention is well suited to the use of microchannel apparatuses for heat exchangers, reactors, and other system components, which may be assembled in slab configuration, further reducing system size and weight.

When you do your search and identify a patent or patent application of interest, make a note of the patent classification code. Then repeat your search using the same code to see patents or patent applications that have been assigned the same code.
I will have more search tips in future posts to this blog.

Fine Print
Online databases like Ebsco’s Academic Search Complete help you keep on top of the technical literature in your area of interest. Here are a couple of tips to help you use Ebsco’s databases more effectively.
1) The Publications Tab. If you are particularly interested in a specific journal and want to find out if the Ebsco database includes it, click the Publications Tab. Then select the “Match Any Words” option and type a keyword of the journal title into the BROWSE box. For example, if the journal you are looking for has the word CATALYSIS in its title, type that into the search box and click the BROWSE button.
The resulting list looks something like this …
Applied Catalysis A: General
Bibliographic Records: 01/10/2002 to present
Applied Catalysis B: Environmental
Bibliographic Records: 01/10/2002 to present
Catalysis Communications
Bibliographic Records: 01/01/2002 to present
Catalysis Letters
Bibliographic Records: 01/01/2003 to present; Full Text: 01/01/2003 to present (with a 12 Month delay)
*Full text delay due to publisher restrictions ("embargo")

*Full text delay due to publisher restrictions ("embargo")
PDF Full Text
2) Read the fine print: Ebsco’s databases contain a combination of full text and non-full text resources. In the list above, for example, the Journal of Catalysis is represented only by Bibliographic Records, whereas Topics in Catalysis is represented both by Bibliographic Records AND by Full Text.
3) Note the dates: even when a journal is represented, the date range may not be sufficient for your needs. What’s more, many publishers allow inclusion of their journals on condition that the most recent issues are not included … the so-called “embargo” mentioned in a couple of the entries in the list above. So if it is important to you to be right up to the minute with a particular journal, you will need to find another source.
1) The Publications Tab. If you are particularly interested in a specific journal and want to find out if the Ebsco database includes it, click the Publications Tab.

Document Delivery Tip: EbscoHost
The Web is a great resource. I am a professional librarian, with a deep appreciation for the books housed by the thousands of libraries in the U.S. and beyond. But I love searching the Web, both for personal use and as a professional researcher.
There is a downside, however. I often identify an article of interest on the Web, but am unable to view the full text.
The first thing I do in this situation is to search for the same article in the various online databases at my disposal. If you work for a corporation with a site license to some of these databases, you should search them to see if the article you want is available through the site license.
If you are an independent consultant, you may not have access to these databases directly. In that case, try your public library.
For example, a Google© search on “dibenzothiphene” turned up the following article:
Deep Desulfurization of Diesel Fuel by Extraction with Task-Specific Ionic Liquids.Preview By: Liu, D.; Gui, J.; Song, L.; Zhang, X.; Sun, Z.. Petroleum Science & Technology, Jun2008, Vol. 26 Issue 9, p973-982, 10p, 4 charts, 1 diagram, 3 graphs; DOI: 10.1080/10916460600695496; (AN 32745488)
Searching Google© on the article title turned up no free full text source of the article.
So I logged onto my Houston Public Library account, searched for the title in EbscoHost, and was able to locate and download the full text of the article, thanks to HPL’s site license with Ebsco.
Contact your local public library to see what sorts of things they offer their users.

WorldCat
Libraries from all over the U.S. participate in a cooperative activity known as ILL – Interlibrary Loan. ILL enables libraries to provide document delivery service to their users. “Document delivery” includes obtaining copies of articles, and borrowing books.
So what does this mean to you, a desulfurization researcher? It means that your corporate librarian, if you have one, can obtain ON LOAN from another library a title such as the one below. If your company does not employ a librarian, or if you are an independent consultant, try your local public library. Houston Public Library, for example, provides access to WorldCat, which makes it easy to search for a key word like “desulfurization.”
Check, as we used to say when I was a kid, it out.
The desulfurization of heavy oils and residua

Do-it-yourself Bibliometrics
Bibliometrics, as I mention in an earlier post, can help pinpoint centers of research in a particular technical area. True bibliometrics requires vast bibliographic databases and sophisticated algorithms for analysis.
Sometimes, though, you can do seat of the pants bibliometrics that will suit your purposes just fine. For example, “Basic Research Needs: Catalysis for Energy (http://www.er.doe.gov/bes/reports/list.html),” a report from the U.S. Department of Energy Basic Energy Sciences Workshop, August 6-8, 2007, lists a number of “Workshop Participants,” each of whom is a significant figure in search for energy solutions. It also lists the organization each participant represents. By putting these two bits of information into a spreadsheet, I was able to sort and resort to reveal a number of possible avenues of research.
For example, although the bulk of participants represent the U.S. Government, it helps me to know which particular government organizations are most represented. Ditto for the university representatives.
Further, although the corporate participants typically only had one or two representatives, the fact that a corporate entity had any interest at all make it worth a second look.
