One way to keep up with developments in your field of research is to follow
companies with a vested interested in those topics of research that match your interests.
Implementing this monitoring strategy is more than simple, but less than
complex.
TIP:
to stay on top of the cutting edge (hmm … that sounds painful), combine key
words with company names
For example, to follow, let’s say, Chevron, you could do worse than to going to
Google® Scholar (https://scholar.google.com/)
and entering a search string like any of the following …

Production of heavy API group II base oil
GD Lei, S Bhattacharya, A Brait - US Patent 9,796,936, 2017 - Google Patents
Abstract
A process for heavy base oil production, comprising: a. performing an aromatic
extraction of a first hydrocarbon feed to produce an aromatic extract, and a
waxy raffinate; b. mixing the aromatic extract with a second hydrocarbon feed
to make a mixed feed having greater than 2,000 wt ppm sulfur; c. feeding the
mixed feed to a hydroprocessing unit to produce a heavy API Group II base oil
having a kinematic viscosity at 70° C. from 22.6 to 100 mm2/s. An integrated
refinery process unit for making heavy base oils, comprising: a. an aromatic
extraction unit fluidly connected to a solvent dewaxing unit and a
hydroprocessing unit; b. a first line from the aromatic extraction unit, that
feeds an aromatic extract to a second hydrocarbon feed to make a mixed feed
having greater than 2,000 wt ppm sulfur; and c. a connection that feeds the
mixed feed to the hydroprocessing unit.

The point is that Googling is helpful, but keywords are … well, key.
AND, it is not that hard. You know that
companies like ExxonMobil, Shell, Chevron and BP are using their people to
research your topic. Piggy back on their
efforts. Combine company names with
simple key words, and you will be rewarded with a wealth of information that
you can use.

Nanotechnology in Oil and Gas Industries
Selective Sulfur Removal from Liquid Fuels Using Nanostructured Adsorbents

Abstract
In recent years, there has been an increasing pressure to develop strategies to reduce the level of sulfur in transportation fuels due to stringent environmental regulations. Currently, hydrodesulfurization (HDS) is the most mature (pre-FCC) technology to remove sulfur from gasoline and diesel. However, conventional HDS can hardly produce ultra-low sulfur fuels while maintaining important fuel requirements (i.e., oxygen content, overall aromatic content, olefin content for gasoline, and cetane number for diesel). As a consequence, improvement of existing HDS processes and development of new desulfurization technologies is needed. In this regard, selective adsorption removal of sulfur (SARS) is a promising emerging approach for ultra-deep desulfurization of refinery streams by means of solid adsorbents. Contrary to HDS, SARS is usually carried out at low temperatures and pressures with minimal hydrogen consumption, preventing olefin hydrogenation and thus maintaining the properties of the fuels. This chapter presents a general overview of SARS. Emphasis is given to the use of nanostructured materials as sulfur adsorbents. Section 5.1 introduces the chapter presenting a general description of HDS, SARS and other emerging desulfurization technologies. Section 5.2 describes the two main groups of SARS (adsorption desulfurization and reactive adsorption desulfurization). Subsequently, the three main mechanisms for sulfur adsorption (p-complexation, direct sulfur–adsorption site interactions, and bulk incorporation in reactive adsorption desulfurization) are reviewed. Section 5.3 gives an overview of relevant literature concerning the use of promising groups of nanostructured adsorbents for SARS including zeolites, MOFs, mesoporous silicas, and carbon-nanostructured adsorbents. Finally, Sect. 5.4 gives some concluding remarks.
