摘要： Disclosed is a reforming-catalyst composition, which comprises nickel oxide and lanthanum oxide as a catalytic material for inducing a reaction between stream and either one of methane, natural gas and town gas to produce a hydrogen-containing gas. The nickel oxide and lanthanum oxide are formed as a perovskite-structured compound partly or in their entirety. The reforming-catalyst composition may include an oxide consisting of either one of alumina, silica and zirconia, on which the perovskite-structured compound is formed to serve as a catalyst carrier. Further, the reforming-catalyst composition may include nickel or ruthenium supported by aforesaid catalyst carrier consisting of the perovskite-structured compound. The reforming-catalyst composition of the present invention allows highly concentrated hydrogen to be produced at a low S/C ratio in steam reforming of methane, natural gas or town gas, while maintaining catalytic activity over a long time-period.
