Abstract: ALKYL BENZENES AND/OR ALKYL NAPHTHALENES ARE DEALKYLATED BY CONTACTING A FEED STOCK RICH IN THESE COMPOUNDS AT ELEVATED TEMPERATURES AND UNDER HYDROGEN PRESSURE WITH A CATALYST COMPRISING A SILICA-ALUMINA CRACKING BASE IMPREDMATED WITH A HYDROGENATION COMPONENT, A SECOND METAL FROM GROUP V-A OF THE PERIODIC TABLE, AND A HALOGEN. THE PREFERRED HYDROGENATION COMPONENT IS NICKEL, THE PREFERRED GROUP V-A METAL IS ARSENIC, AND THE PREFERRED HALOGEN IS FLUORINE. IN THE RECOVERED PRODUCT, AT LEAST A PORTION OF THE COMPOUNDS HAVE A REDUCED NUMBER OF ALKYL GROUPS
