热等离子体与催化剂协同重整ch4-co2
, PP. 328-334
Keywords: 甲烷,二氧化碳,协同作用,催化剂,等离子体
Abstract:
？考察了热等离子体与催化剂协同作用于重整反应过程。实验采用三种不同的模式进行:等离子体单独作用、等离子体与催化剂协同作用、等离子体与催化剂协同作用且部分原料气引入等离子体放电区。结果表明,在模式三下,当原料气的总流量为5m3/h、ch4/co2物质的量比为4/6、等离子体的输入功率为14.4kw时,ch4-co2重整过程可获得最佳结果,ch4转化率为77.00%、co2转化率为62.40%、h2选择性为96.70%、co选择性为88.60%、反应比能为193kj/mol、过程的能量转化率为66.4%,该结果已十分接近ch4-h2o(g)重整的技术指标。最佳结果主要得益于模式三下的三种不同的反应路径,放电反应、热化学反应与催化反应。
