摘要：

The conversion of methane to liquid fuels is still in the development process. The modified HZSM-5 by loading with Tungsten (W) enhanced its heat resistant performance, and the high reaction temperature (800 degrees C) did not lead to the loss of W component by sublimation. The loading of ZSM-5 with Tungsten and Copper (Cu) resulted in an increment in the methane conversion, CO(2), and C(5+) selectivities. The high methane conversion and C5+ selectivity, and low H(2)O selectivity are obtained by using W/3.OCu/ZSM-5. The optimization of methane conversion over 3.0 W/3.OCu/ZSM-5 under different temperature and oxygen concentration using response surface methodology (RSM) are studied. The optimum point for methane conversion is 19% when temperature is 753 degrees C, and oxygen concentration is 12%. The highest C(5+) selectivity is 27% when temperature is 751 degrees C, and oxygen concentration is 11%.
