“If one tells the truth, one is sure sooner or later to be found out” -- Oscar Wilde (Irish Poet, Novelist, Dramatist and Critic, 1854-1900)

I found the following interesting article today, and, wonder of wonders, the full text is available at no charge.

Abstract
An unsupported MoS2 catalyst was prepared by in situ decomposition of ammonium thiomolybdate (ATM)in the presence of water. The catalyst was characterized by XRD, scanning electron microscopy (SEM) andspecific surface area measurements (BET, BJH). Its catalytic activity was evaluated for the hydrodesulfurization(HDS) of diesel oils (straight run gas oil, SRGO and light cycle oil, LCO). Selected refractory sulfur compounds:benzothiophene (BT), dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT) in oils were investigated. The high catalytic activity resulted from the large surface area of the catalyst due to water addition.Reactivity order of the sulfur compounds were determined. The results showed that the reactivity order in SRGOwhich contains nitrogen content is different from that in LCO. This reveals that matrix effect of the oil has someinfluences on the reactivity of the sulfur compounds.

How I found it:
I conduct periodic searches for “dibenzothiophene,” since it is one of the more difficult components to remove from heavy crude.

I like to search Google® Scholar, because it returns patents as well as scholarly articles.

I also like to focus on what the oil majors are doing, because their research tends to be more application oriented.

So here is the simple search statement that resulted in the article highlighted above …

Google Scholar: dibenzothiophene exxonmobil
