Abstract
Abstract Hydrocarbons are converted with a catalyst comprising a Group VIII metal component combined with a support containing alumina and finely divided crystalline mordenite particles. Key feature of the process involves the critical quantity of mordenite present in the composition, thereby effecting and maximizing some basic enhancement of the ability of the resultant catalyst to accelerate hydrocarbon conversion reactions that depend on carbonium ion intermediates: that is, the activity level of the resultant composite is markedly increased.

Claim 1
Independent Claim
128 words
A HYDROGEN-CONSUMING PROCESS FOR SELECTIVELY PRODUCING LPG FROM A HYDROCARBON CHARGE STOCK BOILING BELOW ABOUT 600*F., WHICH COMPRISES CONTACTING SAID CHARGE STOCK AND HYDROGEN WITH A CATALYST COMPRISING A GROUP VIII METAL COMPONENT COMBINED WITH AN ALUMINA CARRIER MATERIAL CONTAINING A UNIFORM DISTRIBUTION OF ABOUT 20 TO ABOUT 30 WEIGHT PERCENT A FINELY DIVIDED MORDENITE PARTICLES AT HYDROCRACKING CONDITIONS INCLUDING A PRESSURE OF ABOUT 300 TO ABOUT 1800 PSIG., A TEMPERATURE OF ABOUT 600*F. TO ABOUT 950*F., A LHSV OF ABOUT 1 TO ABOUT 10 HR.-1 AND A HYDROGEN CIRCULATION RATE OF ABOUT 5000 SCFB TO ABOUT 15,000 SCFB BASED ON FRESH CHARGE STOCK, SAID CATALYST HAVING BEEN PREPARED BY COMMINGLING SAID MORDENITE WITH AN ALUMINUM HALIDE SLO, GELLING THE RESULTANT MIXTURE AND THEN CALCINING THE GELLED MIXTURE.
