摘要
通过在催化剂制备过程中和在原料气中分别引入氯化物,研究了氯对CH_4在Li/MgO催化剂上氧化偶合反应的影响。在常压、T=750℃、P_(CH_4)=23kPa、P_(CH_4)/P_(O_2)=2、W/F=600g·s·1^(-1)等条件下,C_2烃选择性可达56％,C_2烃收率可达27.7％,且在两种情况下C_2烃中的乙烯含量都在90％以上。
The effect of chlorine on oxidative coupling of methane over Li/MgO catalysts was studied by introducing chlorine into Li/MgO catalysts during preparation and by introducing CH_3Cl into feed gives. The effect of reaction temperatures was also examined. An active catalyst gives a C_2 yield of 27.7％ and a C_2H_4/C_2H_6 ratio of 93.8％ under the following conditions, T=750℃, P_(CH_4)=23kPa, CH_4/O_2=2, W/F=600g·s·l^(-1).
