Hydrotreatment catalyst activity enhancement. Quarterly report No. 11, February 1-April 30, 1986. [With and without titanocene dichloride using Shell 324 or Shell 344 catalysts]
Chromatographic analysis results of twenty-one model compound hydrogenation runs are presented. The effect of titanocene dichloride on conversion depends on the extent of catalyst presulfidation. The coke content of catalyst in the runs with titanocene dichloride are much lower than the ones without titanocene dichloride when the feedstock is Tetralin and the catalyst is Ni-Mo/alumina. Catalyst presulfidation procedures also affect coke content on the catalyst. The catalyst which is presulfided under more severe conditions has less coke formed on it. When the feedstock is changed to the mixture of decalin, quinoline, methyl isobutyl ketone and carbon disulfide, the same coke content reduction effect is shown only on the Co-Mo/alumina catalyst. For the Ni-Mo/alumina catalyst, the coke contents on the catalysts are not significantly different for the runs with and without titanocene dichloride. In six noncatalytic runs, the formation of free radicals in SRC-II middle distillate at different temperatures were also measured. 5 refs., 30 tabs.
