研究了Ni/γ- al2o3催化剂上介质阻挡放电对co2重整甲烷转化甲烷的影响。反应的主要产物为CO、H2、C2H6、C3H8和C4H10。考察了输入功率、总流量和CH4/ co2比对转化率和产物选择性的影响。二氧化碳和甲烷的转化率随着输入功率的增大和总流量的减小而增大。Ni/γ- al2o3催化剂对CO选择性和co2转化率有较大影响。当Ni/γ- al2o3催化剂应用于DBD时，CO选择性从49.17%提高到60.9%，co2转化率提高约3%。尽管Ni/γ- al2o3催化剂有助于提高co2转化率和CO选择性，但反应的基本机理和催化剂的表征仍不清楚，因此有必要进一步研究。
A study of methane conversion from CO2reforming of methane using dielectric barrier discharge over Ni/γ-Al2O3catalyst was performed. The main products of reactions were CO, H2, C2H6, C3H8, and C4H10. The effects of input power, total flow rate, and CH4/CO2ratio on conversion and product selectivity were investigated. Carbon dioxide and methane conversions were enhanced with increasing the input power and decreasing the total flow rate. Ni/γ-Al2O3catalyst had a great effect on the CO selectivity and CO2conversion. When Ni/γ-Al2O3catalyst was applied to DBD, the CO selectivity increased from 49.17 to 60.9% and CO2conversion increased by about 3%. Even though Ni/γ-Al2O3catalyst was helpful to improve the CO2conversion and CO selectivity, the fundamental mechanism of reaction and characterization of catalysts are still unknown and, therefore, further investigations are necessary.
