1,171,535. Cracking hydrocarbons. MOBIL OIL CORP. 28 Sept., 1967 [28 Sept., 1966], No. 44231/67. Heading C5E. A process for cracking a hydrocarbon oil to produce hydrocarbons of lower molecular weight comprises contacting said oil with a crystalline aluminosilicate cracking catalyst at a temperature of 1100-1350‹ F. and at a space velocity such that no more than 10% thermal cracking would occur if the catalyst were not present and at a catalyst to oil ratio no higher than 0.1. In examples, Zeolite X (in rare-earth form) and Zeolite Y (in ammonium form) were used to crack gas oils to gasoline. |
