Abstract

A process is disclosed for the dehydrocyclodimerization of light aliphatic hydrocarbons into aromatic hydrocarbons. The process provides improved per pass conversion and an improved yield structure by increasing the relative percentage of xylene which is produced as compared to benzene. This improvement is achieved by recycling benzene recovered from the reaction zone effluent to the reaction zone.
