Abstract
A process is disclosed for the conversion of a light aliphatic hydrocarbon, such as propane, into benzene and optionally also naphthalene. The feed hydrocarbon is converted to aromatic hydrocarbons in a dehydrocyclodimerization zone. The aromatics, and other cyclic hydrocarbons, are passed into a hydrodealkylation zone which is preferably supplied with hydrogen produced in the dehydrocyclodimerization zone. Benzene may be separated from the effluent of the dehydrocyclodimerization zone prior to passage of the aromatics into the hydrodealkylation zone.
