PURPOSE: To obtain an aromatic hydrocarbon in high conversion and high selectivity, by contacting a low-boiling paraffin with a zeolite catalyst having a particular metal system supported on a carrier.
CONSTITUTION: An aromatic hydrocarbon is obtd. by contacting a hydrocarbon contg. a 3W6C low-boiling paraffin as a raw material with a zeolite catalyst comprising a carrier and, supported thereon, a combination of at least one metal selected from the following group A and at least one member selected from the following group B at a temp. of 300W750°C under a pressure of 120atm or less. Group A metals are copper, zinc, gallium, cadmium, silver, indium, aluminum, thallium, titanium, and zirconium. Group B metals are platinum, palladium, nickel, ruthenium, osmium, iridium, rhodium, iron, cobalt, lanthanum, and cerium.
