Abstract
A catalytic process is provided for cracking a hydrocarbon charge stock containing aromatic nuclei components and non-aromatic nuclei components which involves contacting such chargestock with a catalyst composition having an alkali metal content less than about 1.5 weight percent and containing a mixture of faujasite and mordenite in which contacting takes place under catalytic cracking conditions of such severity that the conversion level exceeds that attributable to conversion of the non-aromatic nuclei portion of the chargestock. Under such conditions, the coke yield is substantially lower than would be obtained with the same catalyst in the absence of mordenite at the same level of conversion.
