Abstract
Abstract This disclosure relates to a method of improving the yieldoctane number relationship of a reformate or reformer effluent by contacting the same at conversion conditions in the presence of hydrogen with crystalline aluminosilicate zeolites characterized by (1) having a silica to alumina ratio greater than 15 (preferably greater than 20); (2) having been crystallized from a solution containing organic cations so that the aluminosilicate as synthesized contains organic cations and (3) having pore sizes such that the aluminosilicate sorbs methyl paraffins at said conversion conditions. The upgrading of reformate or reformer effluent can take place with or without added hydrogen and with or without a hydrogenation/dehydrogenation component.
