从微波加热对煤的除湿干燥,微波辐照对煤可磨性的影响,微波在煤炭脱硫领域的应用和煤的微波热解等方面对微波技术在煤炭加工利用过程中的应用情况进行了综述,指出微波技术具有选择性加热材料、穿透性强、升温速率快、加热效率高、易于控制和安全卫生无污染等特点,使其在煤炭领域中的应用具有广阔前景.%The Ni/Al2O3 catalyst coated in the inner wall of micro-channel prepared by precipitation method was employed to conduct experiments of methane-wet air catalytic refor ming. The influence of catalytic temperature, air/CH) mole rate of the raw gases and the CH4 volume flow rate on CH4 conversion were investigated and compared by the simulation results. The ex periment results show that CH4 conversion was increasing by the catalytic temperature increased, and also increased by increasing the air/CH4 mole rate; but with the increase of CH4 volume flow rate of the reaction gases, CH4 conversion increased first and then decreased. When the tempera ture was 1 023 K, CH4 volume flow rate was 20 mL/min, CH4 conversion got a maximum value 61.3%.
