Document Type and Number:

Japanese Patent JPH0683787

Kind Code:

B2

Abstract:

PURPOSE:To obtain a high-efficiency catalyst capable of performing steam reforming without the addition of alkali metal elements, etc., by allowing a porous body of aluminum oxide having specific pore characteristics to hold noble metals. CONSTITUTION:As a carrier for steam reforming catalyst, a porous body of aluminum oxide in which the volume of pores with 0.1-0.5mum pore diameter and the volume of pores with >=0.5mum pore diameter are regulated to >=0.2ml/g and >=0.05ml/g, respectively, and also impurity in ignition drying is regulated to >=98wt.% is used. Then, noble metals, such as ruthenium and rhodium, are incorporated into the above porous body by 0.3-5wt.% based on the weight of the whole catalyst. The resulting catalyst is highly active without the addition of alkali metal elements, etc., and reduced in the deterioration in activity due to carbon deposition.
