EFFECT OF CATALYSTS ON METHANECONVERSION TO C2 HYDROCARBONS IN EFEP REACTION
摘要
Abstract
In this investigation, a clean and direct conversion of methane to C2 hydrocarbons (ethane, ethylene and acetylene) in low-power EFEP(Electric Field Enhanced Plasma) reaction was developed under room temperature and atmospheric pressure. Methane can be converted into ethane, ethylene and acetylene in different selectivity and conversion depending on the discharge voltage, power of plasma, flow rate of methane and nature of catalyst. The effect of catalyst on methane conversion to C2 hydrocarbons was studied under different discharge voltage, power of plasma, flow rate of methane and catalyst. The function of catalyst was tested and compared. The mechanisms of reaction were discussed. The selectivity of C2 hydrocarbons was above 95%. The appropriate condition was voltage of 20?kV～40?kV, power of 20?W～40?W. The appropriate inlet flow rate of methane was 30?mL/min～70?mL/min. The sequence of the conversion of methane was MnO2/Al2O3>Ni/Al2O3>MoO3/Al2O3>Ni/NaY>Pd/ZSM-5>Ni/H4Mg2Si3O4>Ni/ZSM-5>Co/ZSM-5>without catalyst in EFEP reaction.关键词
