ABSTRACT:
A process is disclosed for the conversion of at least a portion of the light hydrocarbons, such as propane, present in a natural gas feed stream into C.sub.6 -plus hydrocarbons including benzene. Noncondensibles such as hydrogen and nitrogen are separated from both the natural gas feed stream and from a reaction zone effluent stream in a common vapor-liquid separation vessel. The liquid stream produced in this initial separation is subjected to fractional distillation which recovers the C.sub.6 -plus product hydrocarbons and a stream of lighter hydrocarbons, which is passed into a dehydrocyclodimerization reaction zone.
