Process for producing high octane gasoline

Abstract From the Canadian patent

A process for producing a high octane gasoline from a hydrocarbon feedstock in which the feedstock is contacted in the presence of hydrogen under hydrocracking conditions preferably ammonia-rich hydrocracking conditions with a, hydrocracking catalyst comprising at least one hydrogenation metal component in combination with a crystalline silico-, aluminophosphate molecular sieve having pores defined by 12-membered rings of oxygen atoms. The preferred silicoaluminophosphate molecular sieve is SAPO-5 molecular sieve and the catalyst preferably contains both a Group VIB metal hydrogenation component, such as molybdenum or tungsten and, a Group VIII hydrogenation metal component such as nickel, …
