Abstract: In a process for converting a high boiling hydrocarbon charge fraction to liquid products of lower boiling range which comprises contacting said charge fraction with a crystalline zeolite characterized by a silica/alumina ratio greater than 12, a constraint index between about 1 and about 12 and an acid activity measured by the alpha scale less than 10, said contacting being conducted at 650 to 850°F., space velocity of 0.1 to 5.0 LHSV and a pressure not less than about 200 psi, the improvement which comprises utilizing, as catalyst, a zeolite of the above character that is prepared by steaming followed by base exchange to substantially eliminate its activity for cracking n-hexane.
