摘要:
A process is provided for effecting hydroisomerization of a C.sub.4 -C.sub.8 paraffin by contacting the same under hydroisomerization conditions with a catalyst comprising a porous crystalline zeolite characterized by a silica/aluminum mole ratio of greater than 12 and a constraint index within the approximate range of 1 to 12, which zeolite has undergone controlled pretreatment by contact with water to enhance the acid activity thereof, expressed as alpha, to greater than about 300. The catalyst also comprises, intimately combined therewith, a minor proportion of a Group VIII metal.
