摘要
研究了冷等离子体与BaO/γ-Al2O3催化剂协同作用下CO2氧化CH4制C2烃反应.结果表明:等离子体与催化剂协同作用效果优于单纯等离子体活化或单纯催化活化;CH4和CO2转化率及C2烃选择性和收率与催化剂负载量、体系能量密度有关;BaO/γ-Al2O3催化剂焙烧温度在500～800℃对催化剂活性影响不大;当体系能量密度为1300kJ/mol时,CH4转化率26.4%,C2烃选择性63.3%,C2烃收率达16.7%.
The synergism of BaO/γ-Al2O3 catalyst and cold plasma used in the reaction of oxidative coupling of CH4 with CO2 to C2 hydrocarbons was studied. The experimental results show that the synergism of catalysts and plasma is better than that of plasma or catalysts alone. The conversion of CH4 and CO2, the selectivity and the yield of C2 hydrocarbons are influenced by the load of catalysts and the energy density of plasma. On the contrary, the calcination temperature of catalyst has little influence on the activity of catalyst at the range of 500-800°C. The yield and selectivity of C2 hydrocarbons were 16.7% and 63.3% respectively with 26.4% CH4 conversion rate over BaO/γ-Al2O3 when the energy density was 1300 kJ/mol.
