Abstract

The HDS of LCO was comparatively studied over commercial γ-Al2O3- and MCM-41-supported Co-Mo catalysts. The HDS of dibenzothiophene (DBT), 4-methyldibenzothiophene, and 4,6-dimethyldibenzothiophene, polyaromatic sulfur compounds present in LCO, and their relative reactivity in terms of conversion were studied as a function of time on stream. The activity of MCM-41-supported catalysts was consistently higher than that of the commercial catalyst. However, the difference in activity was much smaller for DBT as compared to that observed for the substituted variants. Through comparative examination, the presence of aromatics in LCO affected the HDS of the substituted DBT extensively.
