Abstract: A method for reactivation of oxide catalysts which have been deactivated by carbonaceous materials deposited thereon in the course of hydrocracking crude oils, coal tars or shale tars and for simultaneously obtaining technical grade hydrogen of 90-95 vol. % purity containing a maximum of 5 percent of carbon monoxide. Catalyst reactivation is effected by a steam-oxygen mixture having a steam-to-oxygen ratio of 7:1 to 10:1, preferably of 9:1, at a temperature of from 600* to 750*C, and under 20-30 atm pressure. Catalyst reactivation yields a gas consisting essentially of carbon dioxide and hydrogen and containing insignificant proportions of H2S, CO and CH4, the removal of CO2 and H2S from the product gas being effected by absorption with water and an alkaline agent under a pressure of 20-30 atm. The method makes it possible to dispense with the CO conversion step.
