Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a production method which enables simultaneous production of methane and hydrogen in high concentrations using, as a raw material, a gas containing carbon monoxide and/or carbon dioxide and hydrogen such as a coke oven gas.SOLUTION: The production method for simultaneous production of methane and hydrogen uses, as a raw material gas, a gas containing carbon monoxide and/or carbon dioxide and hydrogen as a raw material gas, and comprises: a methanation step of methanating the raw material gas by making a catalyst act on at least a part of the raw material gas; and a hydrogen separation step of permeating and separating hydrogen from any gas inside the system.SELECTED DRAWING: Figure 1 【課題】コークス炉ガス等、一酸化炭素及び／又は二酸化炭素と水素とを含有するガスを原料とし、メタン及び水素を高濃度で併産することが可能な製造方法を提供する。【解決手段】一酸化炭素及び／又は二酸化炭素と水素とを含有するガスを原料ガスとし、原料ガスの少なくとも一部に触媒を作用させて原料ガスをメタン化するメタン化工程と、系内の何れかのガスから水素を透過分離する水素分離工程とを有することを特徴とする、メタン及び水素を併産する製造方法。【選択図】図１
