考察了催化剂中吸波材料SiC的添加对微波辐照下甲烷部分氧化制合成气反应的影响。实验结果表明 ,吸波材料SiC的添加改善了催化剂的吸波性能 ,提高了微波辐照下催化剂的甲烷部分氧化制合成气的催化活性。微波辐照与常规电炉加热下催化剂催化反应的结果比较说明 ,取得相同的甲烷转化率时 ,微波辐照下催化剂的床层温度远低于常规电炉加热下的 ,这归因于微波的“热点”效应。 The effects of microwave absorbing SiC material on the reaction of partial oxidation of methane to syngas under microwave irradiation were investigated. The experimental results show that the addition of microwave absorbing material SiC improves the microwave absorbing performance of the catalyst and enhances the catalytic activity of partial oxidation of methane to syngas under microwave irradiation. Microwave irradiation and conventional electric furnace catalyst catalytic reaction results show that to achieve the same methane conversion, the microwave irradiation under the catalyst bed temperature is much lower than the conventional electric furnace heating, which is attributed to the microwave “hot spots ”effect.
