ABSTRACT:
A naphtha feed is contacted in a reaction vessel with a dehydrocyclization catalyst comprising a large-pore zeolite containing at least one Group VIII metal to produce an aromatics product and a gaseous stream, the aromatics product is separated from the gaseous stream and is passed through a molecular sieve which adsorbs paraffins present in the aromatics product, then the gaseous stream is used to strip the paraffins from the molecular sieve, and the gaseous stream and the paraffins are recycled to the reaction vessel.
