摘要

选用泡沫金属(Fe-Ni)作为催化剂载体

通过浸渍法制备了整体式催化剂(Pd/Al2O3/Fe-Ni)。然后使用该泡沫金属载体整体式催化剂在微小燃烧器中对低浓度甲烷进行催化燃烧实验

分析了燃烧器温度、甲烷浓度以及流量对甲烷转化率的影响。结果表明

随着燃烧反应器内温度的升高

混合气体总流量的降低和甲烷浓度的增大

甲烷的转化率增大;进一步分析表明温度是影响转化率最关键的因素

当燃烧反应器内温度为550℃

甲烷浓度为5%

总流量为50 ml·min-1时

甲烷的转化率可以达到98.7%。

Abstract

The Fe-Ni alloy metal (70%Fe-30%Ni) foams were used as a base material for the catalyst support

and the metal foam based monolithic catalysts (Pd/Al2O3/Fe-Ni) were prepared by wet impregnation. Then experimental study the catalytic combustion of low concentration methane in micro-combustor over metal foam monolithic catalyst. It analyzed the influences of reactor temperature

CH4 concentration and flow rate on methane conversion rate. The results showed that conversion rate increased with the increase of reactor temperature and the decrease of mixture flow rate and the increase of CH4 concentration. Further analysis showed that the temperature is the key factors for CH4 conversion. When the reactor temperature is 550℃

CH4 concentration is 5%

mixture flow rate is 950 K

the conversion rate of CH4 can achieve to 98.7%.
