Chemistry and catalysis of coal liquefaction: catalytic and thermal upgrading of coal liquids: and hydrogenation of CO to produce fuels. Volume V. Final report. [5,6-benzoquinoline, 7,8-benzoquinoline, phenanthridine]
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..-Al/sub 2/O/sub 3/ and NiMo/..gamma..-Al/sub 2/O/sub 3/ as catalysts. Changes in product composition as a function of experimental variables (reaction time, reaction temperature, catalyst type, and H/sub 2/S (CS/sub 2/) 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.
