ABSTRACT:
In a hydrocarbon conversion process for the catalytic desulfurization of a hydrocarbon feedstock the process is carried out at a low hydrogen partial pressure to obtain formation of a low sulfur product and conversion to butanes and propane, as desired, wherein the isoC.sub.4
-C.sub.4 ratio is high, the process being carried out in the presence of an active, stable and selective catalyst containing at least one noble metal component incorporated with a crystalline aluminosilicate. A pressure from 100 to below 500 psig is used. The process contemplates simultaneously pretreating reformer feedstock in the presence of a hydrocracking catalyst with controlled hydrocracking thereof. Preferred highly effective catalysts are those containing palladium incorporated with a crystalline aluminosilicate zeolite.
