Kinetics and mechanism of desulfurization and denitrogenation of coal-derived liquids. Fourth quarterly report, March 20--June 20, 1976
The high-pressure liquid-phase flow microreactors are operating satisfactorily in both hydrodesulfurization and hydrodenitrogenation studies after minor modifications to allow in situ sulfiding. The hydrodesulfurization of dibenzothiophene occurs by a simple network giving only H/sub 2/S and biphenyl as primary reaction products. The reaction network for quinoline hydrodenitrogenation has been determined, and a kinetic model developed to allow quantitative determination of the first-order kinetic constants for each of the steps in the reaction network. The effect of H/sub 2/S concentration, hydrogen pressure, quinoline concentration, and catalyst type on the rate of the various steps in the reaction network has been determined. Aged catalyst from the 1.1 in ID Synthoil reactor showed considerable amounts of mineral matter on it, but not as much FeS/sub x/ as on the catalyst from the /sup 5///sub 16/ in. ID unit. Moment analysis for the evaluation of pulse microreactor data has been completed.
