摘　　要：本文在自行搭建的催化燃烧实验台上,用贵金属催化剂进行了低浓度甲烷燃烧实验,研究了催化剂活性组分、催化剂载体、甲烷浓度、混合气流速和温度对甲烷转化率的影响。结果表明,钯-铑催化剂起燃温度最低为280℃,铂催化剂均在300℃以上。钯-铑催化剂的甲烷转化率最高可达90%,而铂催化剂最高仅为75%。因此,钯-铑催化剂更适合于甲烷催化燃烧。A low concentration methane catalytic combustion experiment has been made with noble metal catalysts. The influences of reaction conditions,including active constituent of catalysts,carriers,reacting gas methane concentration,velocity and temperature,on methane conversion rate have been investigated. The results show that the minimum ignition reaction temperature of palladium-rhodium catalyst is 280℃,while this temperature of platinum catalyst is above 300℃. The maximum methane conversion rate of palladium rhodium catalysts can reach 90%,but this rate of platinum catalyst is about 75%. Therefore,palladium-rhodium catalysis is more suitable for catalytic combustion of low concentration methane.
