Abstract:
1. A process for reforming a hydrocarbon with carbon dioxide using a selectively permeable membrane reactor including a catalyst for accelerating a chemical reaction and a selectively permeable membrane exhibiting selective permeability, wherein a carbon dioxide reforming reaction of the hydrocarbon is accelerated by the catalyst to produce reaction products including hydrogen, and the hydrogen is allowed to pass through the selectively permeable membrane so that the hydrogen is selectively separated from the reaction products, the process comprising the steps of: adding steam to a raw material gas containing the hydrocarbon and the carbon dioxide to form a raw material gas mixture; and supplying the raw material gas mixture to the selectively permeable membrane reactor; wherein the hydrocarbon is methane, a molar composition ratio of the carbon dioxide to the methane (CO
