The present disclosure relates to a naphtha reforming process for obtaining reformed naphtha comprising contacting naphtha with a catalyst, the catalyst comprising a chloride free zeolite coated alumina support impregnated with 0.01 wt % to 0.5 wt % active metal and 0.01 wt % to 0.5 wt % promoter metal, wherein the thickness of the zeolite coating on the alumina support ranges from 100 m to 200 m, which results in formation of reformed products of naphtha and ethylbenzene formed in-situ.

The invention relates to the production of aromatic hydrocarbon by the conversion of a feed comprising saturated hydrocarbon. At least a portion of the saturated hydrocarbon is converted to olefinic hydrocarbon. Aromatic hydrocarbon is produced from at least a portion of the olefinic hydrocarbon using at least one dehydrocyclization catalyst comprising dehydrogenation and molecular sieve components.

The invention relates to converting non-aromatic hydrocarbon in the presence of CO.sub.2 to produce aromatic hydrocarbon. CO.sub.2 methanation using molecular hydrogen produced during the aromatization increases aromatic hydrocarbon yield. The invention also relates to equipment and materials useful in such upgrading, to processes for carrying out such upgrading, and to the use of such processes for, e.g., natural gas upgrading.

The invention relates to the production of aromatic hydrocarbon by the conversion of a feed comprising C.sub.2+ non-aromatic hydrocarbon, e.g., natural gas. The invention is particularly useful in converting natural gas to liquid-phase aromatic hydrocarbon, which can be more easily transported away from remote natural gas production facilities. The conversion is carried out in the presence of a dehydrocyclization catalyst comprising dehydrogenation and molecular sieve components. The dehydrocyclization catalyst has an average residence time of 90 seconds or less.
