Abstract
A high-activity nickel type catalyst, which comprises a carrier compound of high-purity ultra-fine single-crystal magnesia having an average particle size of 100 to 2000 .ANG. or a BET specific surface area of 6 to 170 m.sup.2 /g and metallic nickel or nickel oxide uniformly and thoroughly dispersed on the surface of the carrier in a supported amount of 0.1 to 50% by weight as metallic nickel. The catalyst exhibits a high activity in the steam reforming of hydrocarbons, methanation of synthesis gases, and hydrogenation of cyclic and alicyclic unsaturated hydrocarbons.
