PROCESS FOR PRODUCING HIGH-OCTANE GASOLINE BASE.

摘要

A process for producing a high-octane gasoline base by treating light hydrocarbons mainly comprising C2 to C7 paraffins and/or olefins in the presence of a catalytic composition containing crystalline aluminogallosilicate as a catalytic component under a hydrogen partial pressure of 5 kg/cm<2> or less at 350 to 650 DEG C, wherein the catalytic component comprises ammonia-modified crystalline aluminogallosilicate prepared by the contact of hydrogen-type aluminogallosilicate with ammonia under a dry condition. A high-octane gasoline base can be advantageously produced from light hydrocarbon by virtue of excellent initial activity and catalyst life of the catalytic component.
