摘要
The present invention relates to a system for utilizing methane by a direct conversion catalytic reaction with improved efficiency, a raw material supply device for supplying a reaction raw material containing methane; A catalytic reaction device for generating reactants by direct conversion of methane; A membrane separation device comprising at least one separation membrane module that separates reactants from unreacted methane; And a reactant recovery device for recovering the reactants separated from the membrane separation device, circulatingly supplying the methane separated from the membrane separation device to a raw material supply device or a catalytic reaction device, and the separator included in the separator module is a porous support. And a silicon-based selective layer formed on the surface of the support. The present invention has an effect of significantly improving the utilization efficiency of methane by a direct conversion catalytic reaction by applying a separator composed of a porous support and a silicon-based selective layer. In addition, by forming the silicon-based selection layer to which the POSS group is attached to the porous support, there is an effect that the separation efficiency of methane is further improved.
