Kinetics and mechanism of desulfurization and denitrogenation of coal-derived liquids. Ninth quarterly report, June 21, 1977--September 20, 1977
Description:
Flow reactor studies of HDS of dibenzothiophene at about 300/sup 0/C and 100 atm have shown a new dependence of catalyst activity on H/sub 2/S concentration at low values. We infer that the catalyst undergoes structural changes during reaction, sometimes becoming sulfur deficient and relatively inactive. It is evidently necessary to maintain the catalyst in a properly sulfided state during reactor startup and operation by avoiding its contacting too little H/sub 2/S. The relative activities of …
