摘要：

The combination of pulsed corona discharges and catalyst was examined for decomposition of pure carbon dioxide in a corona reactor packed with porous gamma -A l(2)O(3) pellets. The decomposition of CO2 was greatly enhanced by packing gamma -Al2O3. In the presence of gamma -Al2O3, the conversion of CO2, yield of CO reach 23 and 15%, respectively. The CO2 conversion increases with increasing applied voltage and decreasing gas flow rate. The maximum energy efficiency for decomposition of CO2 reaches 318.7 g/k W hr. It was found that high surface area of gamma -Al2O3 and strong adsorption capacity of CO2 on gamma -Al2O3 play an important role in CO2 decomposition under corona discharges. At the same time. the presence of gamma -Al2O3 suppresses the reaction of CO and O.
