Hydrotreatment catalyst activity enhancement. Quarterly report No. 6, November 1, 1984-January 31, 1985
Twelve hydrogenation runs were conducted in the newly constructed Berty type, gradientless minireactor. In the first six runs Tetralin was hydrogenated on a commercial Ni-Mo/alumina catalyst with varying stirrer speeds. The optimum speed was determined to be 1500 rpm. the other six runs used Tetralin and a mixture of Tetralin and 5% phenanthrene as the feedstock. The experimental conditions were very similar to those of our earlier study in a trickle-bed reactor. The objective was to study the effects of addition of titanocene dichloride to the feed and check the operation of the two reactors against each other. The hydrocarbon conversion results confirm the results of the trickle-bed reactor. Addition of titanocene dichloride enhances the hydrogenation of Tetralin, but has minimal effect on the hydrogenation of a mixture of Tetralin and phenanthrene. An important observation is the accelerated catalyst deactivation in the gradientless reactor, which requires approximately one-fifth of the time of a trickle-bed to achieve a similar deactivation.
