Steam reforming catalyst.

摘要

A steam reforming process is improved by the use of a catalyst comprising a porous aluminum oxide having a pore volume of pores having a pore diameter ranging from 0.1 to 0.5 micron of not less than 0.2 ml/g and a pore volume of pores having a pore diameter of more than 0.5 micron but not more than 10 microns of not less than 0.05 ml/g and a purity determined upon ignition dryness of not less than 98% by weight, and nickel in an amount of 3 to 20% by weight in terms of nickel oxide based on the total weight of the catalyst, said catalyst being formed by impregnating said porous aluminum oxide with a solution containing nickel, drying the impregnated aluminum oxide and then calcining the dried aluminum oxide.
