METHOD OF PREPARING HYDROCARBON-DEHYDROGENATION CATALYSTS

摘要

FIELD: hydrogenation-dehydrogenation catalysts. SUBSTANCE: method involving applying catalytic VII group metal onto carrier and subsequent modification with additional metal is distinguished by that the latter is added to calcined and activated mass of precatalyst containing at least one carrier and at least one VII group metal and it is added in the form of either pure metal compound or in situ diluted into reaction zone where charge is treated in presence of above-defined catalyst or into prezone being in immediate contact with reaction zone. EFFECT: improved catalyst characteristics. 21 cl, 4 tbl, 7 ex
