Abstract
The present application relates to the technical field of low carbon alkane conversion, and particularly relates to a kind of plasma reactor and the method for low carbon alkane conversion, the plasma reactor includes reactor body and at least one electrode arranged in the reactor body, it further includes the flow guide tube arranged in the reactor body, the distance from the upper end of the flow guide tube to the lower part of the reactor body is greater than the distance from the lower end of at least one electrode to the lower part of the reactor body, and the lower end of the flow guide tube extends to the downstream of reactant stream direction.The flow guide tube is additionally arranged in the reactor body, so that the raw material gas more concentratedly passes through the plasma area, and the flow guide tube reduces the flow area, improves the inlet gas flow rate, which is conducive to improving the non-equilibrium type of sliding arc;it can improve the conversion rate of low carbon alkane in low carbon alkane conversion, and is especially suitable for methane conversion.
