ABSTRACT:
A process is disclosed for the catalytic conversion of an olefin-containing C.sub.3 and/or C.sub.4 feed (1) into aromatic hydrocarbons (22) and C.sub.3 and/or C.sub.4 paraffins (25,26). The process may result in a net consumption of hydrogen and operates at relatively mild temperature conditions, with preferred temperatures in the reaction zone (4) being less than 425 degrees Celsius. The severity of the operating conditions and the length of time the catalyst is used are controlled to hold down total carbon deposition and to increase aromatics selectivity. A catalyst comprising gallium supported on a zeolite containing base is preferred. The feed stream contains a mixture of paraffins and olefins, with aromatics production being directly related to feed olefin content.
