DEHYDROCYCLODIMERIZATION PROCESS", ABSTRACT A hydrocarbon conversion process for the production of C6-C8 aromatic hydrocarbons from C3 and C4 aliphatic hydrocarbons is disclosed. This dehydrocyclodimerization process is characterized by the integrated product recovery steps employed to separate hydrogen and products from the reactor effluent. Following partial condensation of the reactor effluent stream, the resultant vapor is subjected to liquid absorption (scrubbing) followed by autorefrigeration to yield lighter gas streams. Liquids from the various steps are separated via fractionation.
