The processes of methane decomposition and formation of C_2 hydrocarbons were studied. The experiment shows that methane decomposition can be divided into three periods as the reaction proceeds. In the first period, a large number of free radicals were formed. While in the last period, the formation of C_2 hydrocarbons and the decrease of free radicals were observed. The time and conditions of methane decomposition and formation of C_2 hydrocarbons are different.展开更多
