(Summary description)Catalytic activities of different types of catalysts under the action of plasma atmospheric plasma: Atmospheric pressure plasma and catalyst co-activate CO2 to oxidize ethane. The main products are ethylene, acetylene and a small amount of methane. Of course, the by-products of ethane deradon reaction with CO2 as oxidant (CO+H2) and a small amount of water are also detectable. The catalytic activity of different kinds of catalysts under the action of atmospheric plasma is shown. , under pure plasma conditions, the conversion rates of C2H6 and CO2 are 33.8% and 22.7%, respectively, and the sum of the yields of C2H4 and C2H2 is 12.7%. When the supported rare earth oxide catalysts (La2O3/Y-Al2O3 and CeO2/Y-Al2O3) were introduced into the reaction system, the conversion of C2H6, the selectivity and yield of C2H4, the selectivity and yield of C2H2 were improved, but the CO2 Conversion rates are slightly lower. When La2O3/Y-Al2O3 and CeO2/Y-Al2O3 were used as catalysts, the yields of C2H4 and C2H2 were 19.8% and 21.8%, respectively. When the Pd/Y-Al2O3; catalyst was introduced into the plasma, the ethylene selectivity was significantly improved, and the C2H4/C2H2 ratio was as high as 7.4, but the C2H6 conversion rate decreased. This is because Pd reduces C2H2 to C2H4 and also reduces C2H4 Caused by C2H6. The above experimental results show that the rare earth oxide catalyst is beneficial to improve the conversion rate of C2H6 and the yields of C2H4 and C2H2, while Pd/Y-Al2O3 is beneficial to the generation of C2H2. Note: The reaction conditions are catalyst dosage of 0.7ml, discharge power of 20W (peak voltage 28kV: frequency 44Hz), flow rate of 25 ml/min, and feeds of C2H6 (50vol.%) and CO2 (50vol.%).
