Abstract: GASEOUS HYDROCARBONS SUITABLE FOR USE IN LIQUIFIED PRETROLEUM GAS, LPG, ARE PRODUCED BY CONTACTING A HYDROCARBON FEEDSTOCK UNDER CONVERSION CONDITIONS IN THE PRESENCE OF A CATALYST COMPRISING A MORDENITE ALUMINOSILICATE, PREFERABLY CONTAINING A GROUP VII METAL HAVING AN ATOMIC WEIGHT GREATER THAN ABOUT 100. IN A PREFERRED EMBODIMENT THE MORDENITE HAS AN INCREASED SILICA TO ALUMINA MOLE RATIO.
