Hydrotreatment catalyst activity enhancement. Quarterly report No. 9, August 1-October 31, 1985

Technical Report ·
OSTI ID:6378342

Hydrogenation of Tetralin in the presence and absence of carbon disulfide was studied. Our presulfidation procedure was modified to achieve more severe sulfidation. In hydrogenation of hydrocarbons, in-situ generation of hydrogen sulfide is required to maintain the catalyst at its sulfided state. Otherwise, a catalyst will lose its activity due to the consumption of the sulfided state which may be mistaken for coking deactivation. Nine model compound runs using decalin, methyl-isobutyl ketone, quinoline, and titanocene dichloride were conducted on a NiMo/alumina and a CoMo/alumina catalyst. One hydrotreatment run using SRC-II distillate was conducted in a trickle bed with periodic doctoring with titanocene dichloride. 6 refs., 7 figs., 10 tabs.
