摘　　要：为实现CO2重整CH4高效转化合成气,以生物质焦为催化剂和吸波介质,开展基于微波辐射的CO2重整CH4制备合成气的实验研究,主要考察反应温度、CO2与CH4摩尔比、生物质焦添加量以及水蒸汽的引入等条件对重整反应转化合成气的影响特性。研究表明,提高反应温度,加大CO2与CH4摩尔比以及增加生物质焦添加量均可促进反应气向合成气转化,但对合成气品质影响不一,升高温度能够提升合成气中H2与CO的比值,而加大CO2与CH4摩尔比和增加生物质焦添加量均会降低H2与CO的比值。水蒸汽的引入强化重整反应的进行,促使合成气中氢碳比的提高。High-grade syngas can be produced from the reforming of CH4 with CO2. To achieve efficient conversion of reforming reaction into syngas production, the reforming of CH4 with CO2 for syngas production was conducted in this paper under microwave irradiation, with biomass char as catalyst and microwave absorbing medium. The influences of the conditions including reaction temperature, molar ratio of CO2 and CH4, addition amount of biomass char as well as the introduction of water vapor on the reforming reaction were investigated. The results reveal that an increase in the conversion of reactant gases into syngas production can be achieved through raising reaction temperature, enhancing molar ratio of COz and CH4 or increasing addition amount of biomass char. Raising reaction temperature results in a promotion in the ratio of H2 to CO, while enhancing molar ratio of CO2 to CH4 or increasing addition amount of biomass char bring about a decrease in the ratio of Hz to CO. And the introduction of water vapor is not only favorable for the reforming reaction, but also is responsible for an increase in the ratio of H2 to CO.
