摘要

采用负载Rh的泡沫独石整体型催化剂研究了甲烷催化部分氧化过程，考察了外界温度、空速和甲烷与氧气进料比例对反应转化率和选择性的影响，并对过程控制条件和调控参数进行了分析。研究结果表明该过程为毫秒级超短接触过程，反应可以在自热条件下进行，高空速条件下（8×105 h-1），甲烷与氧气进料比（体积比）为1.8，甲烷转过率超过90%，CO选择性接近95%，H2选择性超过90%。外界加热对过程有利，可获得更高的转化率和选择性。

Abstract

The catalytic partial oxidation of methane (CPOM) to syngas was studied on a rhodium coated foam monolith catalyst.The influences of reactor temperature

space velocity and methane/oxygen ratio were investigated and discussed.The reaction could be maintained auto-thermally after ignition.Under the conditions of high space velocity (8.0×105 h-1) and methane/oxygen ratio of 1.8

the methane conversion

hydrogen selectivity and carbon monoxide selectivity exceeded 90%

90% and 95%

respectively.Heat supply to the reactor increased methane conversion and selectivity to hydrogen and carbon monoxide.
