摘　　要：载体是催化剂活性组分的分散剂、粘合剂和支持物,其作用是多方面的,它是催化剂的重要组成部分。我们选择了γ Al2O3、SiO2、MgO和ZnO等几种具有代表意义的催化剂载体,考察了它们对等离子体活化CH4/H2转化反应的影响。实验结果表明:在脉冲电晕等离子体条件下,催化剂载体对CH4/H2活化与转化存在一定的影响,不同的载体对CH4/H2转化显示出不同的活性,其中SiO2对C2烃选择性作用明显高于无载体参与时和其它载体,C2烃收率也明显高于其它载体。Carrier has much functions,it is an important parts of dispersant,bond and supporter of catalyst.The paper studied for the catalytic activation of γ-Al_2O_3,SiO_2,MgO and ZnO,by the conversion of CH_4/H_2 under plasma at atmospheric pressure and ambient temperature. The experiment results showed those carriers have obvious catalytic performance on the conversion of CH_4/H_2 under pulse corona plasma,and it is different to every carrier.The selectivity of C_2 hydrocarbons for SiO_2 was evidently more than that of the others and no carrier,and the yield of C_2 hydrocarbons of SiO_2 was evidently more than that of the others.
