Five experimental runs were completed with the objective to evaluate quinoline feed concentration effects. In all five experiments the pressure was maintained at 12.4 MPa with a space time of 0.5 h with a temperature of 350/sup 0/C, except for one experiment which had a temperature of 370/sup 0/C and space time of 1.0 h. All experiments used a Topsoe TK-771, Ni-Mo catalyst. The concentrations of quinoline in the feedstocks varied from 10 to 20 to 30 wt % in n-hexadecane. Product analyses revealed that the quinoline in the feedstock inhibited the hydrocracking steps causing the primary product, propylcyclohexane, to decrease with increasing quinoline in the feedstock. Remaining intermediate products from the reaction network followed the same trend with changes in feedstock concentration of quinoline with exception of 5,6,7,8-tetrahydroquinoline and propylbenzene. Increasing quinoline concentration in the feedstock also resulted in marked increase in deactivation of the catalyst for overall nitrogen removal. 6 figs., 6 tabs.
