Hydrotreatment catalyst activity enhancement. Quarterly report No. 12, May 1-July 31, 1986. [Effect of titanocene dichloride and sulfidation on catalyst coking]
Catalyst coking results from the runs of model compound studies of the previous quarters were plotted. These graphs clearly show that coke contents 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. The effect is more pronounced when the catalyst sulfidation is not adequate. When the feedstock is decalin mixed with carbon disulfide, methyl-isobutyl-ketone, and quinoline the effect of titahocence is not significant on the Ni-Mo/alumina catalyst, but it is significant on the Co-Mo/alumina. Twenty-two additional runs with mixtures of Tetralin, carbon disulfide, methyl-isobutyl-ketone and quinoline on Ni-Mo/alumina and Co-Mo/alumina catalysts were conducted. A simulated distillation technique was developed and used to analyze samples from the SRC-II middle distillate runs. Preliminary analysis indicates that titanocene dichloride lowers the high boiling fraction and increases the low boiling point fraction of the oil. 1 ref., 2 figs., 31 tabs.
