- Metal containiiig ZSM-5 can produce higher hydrocarbons in metallane oxidation. Many researchers have studied the applicability of HZSM-5 and modify ZSM-5 for ruethane coriversion to liquid hydrocarbons, but their research results still lead to low conversion, low selectivity and low heat, resistancc. The modified I-IZSM-5, by loading with tungsten (W), could eriharice its heat resistant performance, arid the high reaction temperature (800 "C) did not lead to a loss of tlie W coniporicnt by sublirna,tion. The loading of HZSM-5 with tungsten and copper (Cu) resulted in an iiicrement in the methane coriversion as well as COz and Cg+ selectivities. In contrast, CO, Ca-3 and Hz0 selectivities wcre reduced. The process of converting methane to liquid hydrocarbons (C5+) was deperideiit on the metal surface area and the acidity of the zeolite. High methane conversion and Cg+ selectivity, arid low HzO selectivit,y arc obtained over W /3.OCu/HZSM .
