Catalyst for steam reforming of hydrocarbons and process for producing hydrogen from hydrocarbons

摘要

A catalyst for reacting hydrocarbon with steam comprising: (a) a porous composite oxide carrier containing magnesium and aluminum; and (b) nickel metal in the form of fine particles carried on the porous composite oxide carrier; wherein the catalyst has a magnesium content of from 5 to 55% by weight, calculated as Mg, based on the weight of the catalyst, an aluminum content of from 5 to 35% by weight, calculated as Al, based on the weight of the catalyst, a nickel content of from 1.2 to 60% by weight, calculated as Ni, based on the weight of the catalyst, a total amount of magnesium, aluminum and nickel of from 50 to 85% by weight, calculated as a sum of Mg, Al and Ni, based on the weight of the catalyst, and a specific surface area of from 40 to 300 m<2>/g, and wherein the fine nickel metal particles have an average particle diameter of not more than 10 nm.
