摘要：

Catalysts for dehydrogenative conversion of methane (DCM) to higher hydrocarbons are worthy of attention. Indium supported on silica (In/SiO2) was found for effective catalyst for the DCM reaction above 1023 K. Products were ethane, ethylene, acetylene, propylene, benzene, toluene, naphthalene and hydrogen. A highest selectivity of sum of products was 96% at 1098 K and a steady-state sum yield was 2.1% with 63% selectivity at 1173 K. Characterization studies using temperature-programed X-ray diffraction (TP-XRD) and scanning electron microscopy (SEM) indicated that the working state of indium catalyst was liquid metal. Effects of reaction temperature on the product distribution and studies of temperature-programed-reaction (TPR) indicated that liquid-metal indium activated methane and selectively converted to ethane. Higher hydrocarbons were produced from ethane in the gas phase without catalyst.
