A process for the upgrading of a hydrocarbon feedstock which includes providing a feedstock including C4 and higher hydrocarbons which include paraffins and cycloparaffinic hydrocarbons; contacting the feedstock with a conventional naphtha reforming catalyst at an elevated temperature and at a liquid hourly space velocity (LHSV) of greater than approximately 5, when the cycloparaffin content is approximately 10% by weight or greater; and contacting the feedstock with a metal-containing ZSM-5 type zeolite catalyst at an elevated temperature at approximately 0.5 to 2 LHSV when the initial cycloparaffin content is reduced to less than approximately 10% by weight, and solely with a metal-containing ZSM-5 type zeolite catalyst at an elevated temperature at approximately 0.2 to 2 LHSV when the initial cycloparaffin content is less than approximately 10% by weight.

A process for the upgrading of a hydrocarbon feedstock which comprises: providing a full naphtha hydrocarbon feedstock having an initial cycloparaffin content of less than approximately 10% by weight and contacting the provided feedstock with a metal-containing Z SM-5 type zeolite catalyst at an elevated temperature at approximately 0.2 to 2 LHSV so as to convert said full naphtha feedstock into an upgraded hydrocarbon product. A process for the upgrading of a hydrocarbon feedstock which comprises: providing a full naphtha hydrocarbon feedstock having a cycloparaffin content of approximately 10% by weight or greater, contacting the provided feedstock with a naphtha reforming catalyst which comprises a platinum group metal at an elevated temperature and at a LHSV of greater than approximately 5 so as to reduce the cycloparaffin content of the provided feedstock to less than approximately 10% by weight and contacting the provided feedstock having the reduced cycloparaffin content with a metal-containing Z SM-5 type zeolite catalyst at an elevated temperature at approximately 0.5 to 2 LHSV so as to convert said full naphtha feedstock into an upgraded hydrocarbon product, wherein the reduction of the naphtha reforming catalyst and the conversion with the zeolite catalyst is conducted in a tubular reactor.
