Summary

This project was concerned with a systematic study of the kinetics of hydrogenation-hydrodenitrogenation (HDN) reactions of condensed carbocyclic-N-heterocyclic model compounds, and of a representative coal liquid. The feeds investigated included 5,6-benzoquinoline; 7,8-benzoquinoline; phenanthridine (3,4-benzoquinoline); N-ethylcarbazole; carbazole; 1,10-phenanthroline; and a SRC-II middle-heavy distillate (b.p. 230 to 430/sup 0/C). The studies were performed in autoclave reactors in the temperature range of 80 to 375/sup 0/C, using sulfided CoMo/..gamma..-Al2O3 and NiMo/..gamma..-Al2O3 as catalysts. Changes in product composition as a function of experimental variables (reaction time, reaction temperature, catalyst type, and H2S (CS2) concentration) were determined. Kinetic rate constants for each step in the reaction networks of the different model reactions were calculatd, and mechanistic aspects of the hydrogenation-HDN reactions were elucidated. 124 refs., 77 figs., 71 tabs.
