制备了吸波性良好的泡沫陶瓷担载镍的甲烷 /二氧化碳重整催化剂 ,并考察了催化剂在微波场中的升温行为 ;研究了微波加热与常规加热对甲烷 /二氧化碳重整制合成气反应的影响 ,发现微波辐照下能有效地消除反应积炭 ;同时 ,在达到相同转化率和选择性时 ,微波加热方式下催化剂床层的温度远低于常规加热方式下催化剂床层的温度 ;在微波加热方式下 ,80 0℃反应时产物中H2 /CO体积比接近于 1 .
Preparation of a good microwave absorbing ceramic supported nickel oxide / carbon dioxide reforming catalyst and investigated the catalyst in the microwave field temperature behavior; study of microwave heating and conventional heating of methane / carbon dioxide to the syngas reaction , It is found that the reaction coke can be effectively eliminated under microwave irradiation. Meanwhile, when the same conversion and selectivity are reached, the temperature of the catalyst bed under the microwave heating mode is far lower than that of the catalyst bed under the conventional heating mode; at Under the microwave heating mode, the volume ratio of H2 / CO in the product at 80 0 ℃ is close to 1.
