Abstract


The growing shortage of oil resources so that people more and more attention to the development and utilization of abundant natural gas resources . Become the key to the conversion of natural gas as the main component of natural gas methane conversion and utilization . Plasma is a very effective means of molecular activation , non-equilibrium plasma has a unique advantage to use its special non-equilibrium in the methane conversion . The nonequilibrium plasma strengthen the conversion of methane to C2 hydrocarbons . Add gas reactor parameters and power parameters of the reaction in the blade - like rotating electrode reactor were investigated . The study showed that : H2 , N2 and Ar added are conducive to the increase in the rate of methane conversion , while H2 can effectively inhibit carbon deposition ; smaller discharge gap and stainless steel electrodes conducive to the conversion of methane ; final power parameters of the reaction can be attributed to the impact of the current pulse parameters of the reaction is not obvious . Comparative blade - shaped rotating electrode reactor with medium barrier by the experimental results of the reactor , the reaction mechanism of the methane conversion speculated . Results : rotate the blade - like electrode reactor , most of the methane molecules are dissociated into CH and C radical , the main product of the reaction is a small amount of acetylene and ethylene , carbon deposition more ; in the dielectric barrier discharge reactor , methane most dissociation of the CH3 , the main product of the reaction of ethane and propane , almost no carbon deposition ; same species discharge type of reactor , the product distribution of the overall trend is consistent ; blade - shaped rotating electrode the methane conversion rate in the reactor is much larger than in the methane conversion rate of the dielectric barrier reactor . In addition , the sliding arc discharge plasma preliminary exploration for methane conversion . The experimental results show that the lower energy consumption sliding arc reactor suitable for the reaction of the large flow of gas plasma conversion of methane industrialized enlarge promising .
