    摘要： A process for preparing supported nickel catalyst consisting of supporting nickel or metal salt of nickel, alkali metal, alkaline earth metal having low melting point on silicon and aluminum-containing support having high surface area such as zeolite, silica and alumina as an oxide by melting effectively nickel or metal salt of nickel, alkali metal and alkaline earth metal having low melting point is disclosed. This process is characterized in that the supported nickel catalyst prepared by the present invention can be used in reforming reaction of hydrocarbons by using carbon dioxide, steam and oxygen as an oxidant. Metal salts used in the preparation of supported nickel catalyst is generally nitrate, chloride, acetate and carbonate having low melting point of 500° C. or less. The contents of nickel, alkali metal and alkaline earth metal of the catalyst are 1 to 20% by weight, 10% by weight or less and 20% by weight or less, respectively. The calcination temperature of the catalyst is in a range of 300° C. to 1200° C.
