EXAMPLE - A feed comprising 50 wt.% natural gas and 50 wt.% of a hydrofined gasoline fraction was contacted at 500 degrees C, 1 MPa and 2000 GHSV with a catalyst comprising 10% ZSM-5 zeolite, 0.4% ionic platinum, 0.1% metallic platinum, 1.5% chlorine and 0.4% tin on alumina. The methane conversion was 37.2% and the product comprised 31.4 wt.% methane, 28.3 wt.% C2-C4 hydrocarbon gases and 40.3 wt.% C5+ liquid hydrocarbons.
