Abstract
A process and a system for reforming and upgrading a heavy naphtha feedstock may include dehydrogenating naphthenes in the heavy naphtha feedstock to form a first effluent stream comprising aromatics and then separating the aromatics via extraction from the produced first effluent stream to produce a second effluent stream containing raffinate paraffins. The process may then include subjecting the second effluent stream to cyclization reactions to produce a third effluent stream comprising aromatics and then combining the first effluent stream and the third effluent stream prior to extraction

A system for producing and separating aromatics from a heavy naphtha feedstock, the feedstock comprising at least paraffins and naphthenes, wherein the system comprises:
- one or more dehydrogenation reactors for converting naphthenes in the heavy naphtha feedstocks into aromatics in a first effluent;
- an aromatic extracting unit for extracting at least a portion of the aromatics from the first effluent to form a second effluent stream of raffinate comprising at least the paraffins;
- and
- one or more cyclization reactors for converting the paraffins in the second effluent stream into aromatics in a third effluent stream.
