Hydrotreatment catalyst activity enhancement. Quarterly report No. 4, May 1, 1984-July 31, 1984. [Titanocene dichloride]
A UV/VIS spectrophotometer was used to study the kinetics of the homogeneous reaction between Tetralin and titanocene dichloride. At 23/sup 0/C, the reaction was found to be first order in titanocene dichloride concentration with a rate constant of 6.17 x 10/sup -6/ 1/sec. The hydrocarbon products from the trickle-bed reactor runs were analyzed. The runs, which were reported in the previous quarterly, were made to study the effects of addition of titanocene dichloride on the hydrotreatment of Tetralin and a mixture of 5% phenanthrene in Tetralin over a Ni-Mo/Alumina catalyst. The results are in agreement with the earlier observations which were based on catalyst coking and distillation curve changes. The spent catalyst samples were also analyzed for total surface area and pore volume. The pore volume decreases with increasing coke content on the catalyst. While the total surface area data are more scattered, they also decrease with the coke content. 13 figures, 6 tables.
