  • Catalyst for steam reforming of hydrocarbons
    Patent number: 4285837
    Abstract: A catalyst for steam reforming of hydrocarbons comprises porous aluminum oxide and nickel oxide, characterized in that the porous aluminum oxide in which the pore volume given by the pores of the pore diameter ranging from 60 to 120 A is not less than 0.35 ml./g. and the pore volume given by the pores of the pore diameter of more than 120 A is not less than 0.1 ml./g. and the purity determined upon ignition dryness is not less than 98% by weight is impregnated with nickel in an amount ranging from 10 to 30% by weight, as converted to nickel oxide basis, based on the total amount by weight of the catalyst.
