Abstract
A process for converting hydrocarbons to aromatic compounds comprising contacting a paraffinic or olefinic hydrocarbon feedstream, without added hydrogen, with a catalyst comprising from about 0.05 to about 5% of palladium metal and from about 0.1 up to 2% chromium oxides composited with a high surface area support. A preferred process is one for aromatization of such feeds by contact with a catalyst comprised of from about 0.05 to about 5% of palladium metal, from about 0.1 to less than 2% chromium oxide and up to about 4.5% by weight of an alkali metal oxide incorporated therewith to increase the aromatization activity of the catalyst. Catalysts used in accordance with the present invention comprise compositions which include from about 0.05 to about 5% palladium, from about 0.01 to less than 2% chromium oxides and up to about 4.5% of an alkali metal oxide.
