Process for cracking hydrocarbons with a crystalline zeolite
First Claim
19. IN A PROCESS FOR THE CRACKING OF A HYDROCARBON CHARGE WITH A SOLID POROUS CATALYST WHEREIN THE PRODUCTS OBTAINED COMPRISES BOTH ECONOMICALLY VALUABLE LIQUID HYDROCARBONS BOILING IN THE MOTOR FUEL RANGE AND UNDESIRABLE BY-PRODUCTS OF LESSER ECONOMIC SIGNIFICANCE, THE IMPROVEMENT IN SELECTIVELY EVIDENCED BY THE PRODUCTION OF A SUBSTANTIALLY GREATER AMOUNT OF SAID VALUABLE LIQUID HYDROCARBONS TOGETHER WITH CONCOMITANT REDUCTION IN THE YIELD OF UNDESIRED BY-PRODUCTS FROM A GIVEN HYDROCARBON CHARGE, WHICH COMPRISES CONTACTING SAID CHARGE UNDER CRACKING CONDITIONS WITH A CATALYST COMPOSITION COMPRISING AN INORGANIC OXIDE MATRIX HAVING DISPERSED THEREIN AN ALUMINOSILICATE HAVING AN ORDERED CRYSTALLINE STRUCTURE AND CONTAINING FROM 0.5 TO 1.0 EQUIVALENT PER GRAM ATOM OF ALUMINUM OF IONS OF POSITIVE VALENCE WHEREIN THE ENHANCED SELECTIVITY OF SAID CATALYST COMPOSITION ARISES FROM THE FACT THAT THE ALUMINOSILICATE HAS ASSOCIATED THEREWITH BOTH HYDROGEN IONS AND CATIONS OF METALS SELECTED FROM GROUP IB THROUGH GROUP VIII OF THE PERIODIC TABLE.
