Catalyst for producing hydrogen from hydrocarbon, method for producing the catalyst, and method for producing hydrogen using the catalyst

摘要

PPROBLEM TO BE SOLVED: To provide a catalyst outstandingly suppressing precipitation of carbon and maintaining a high activity even when a hydrogen production reaction using heavy hydrocarbon such as kerosene as a material is performed, and a production method for the catalyst and a production method for hydrogen using the catalyst. PSOLUTION: In the catalyst for producing hydrogen from the hydrocarbon, on an inorganic oxide carrier, ruthenium is contained in 0.5-10 mass% based on the catalyst in terms of metal and an alkali metal is contained in 0.5-10 mass% based on the catalyst in terms of metal, a dispersion degree of ruthenium is 50% or more and when, by EPMA, a line analysis measurement is performed regarding the alkali metal and ruthenium from an outer surface of the catalyst to the other outer surface in one direction so as to pass through a center of a cross section of the catalyst, the large amount of alkali metal also exists at an area where ruthenium exists. The production method for the catalyst and the production method for hydrogen using the catalyst are provided. PCOPYRIGHT: (C)2007,JPO&INPIT
