Abstract
A catalyst for reforming of hydrocarbons with less reduction in activity. An improved steam-reforming catalyst for hydrocarbons, wherein the active component Ni is supported on an &agr;-Al,O,or CaO—Al,O,carrier, a part of the active component Ni is combined with the carrier to form a compound NiAl,O,, and carbon is contained in both of the Ni and NiAl,O,components, and the grating constant of Ni and the grating constant of NiAl,O,in the catalyst are increased as compared with those of the catalyst before carbon is added to in both of the said components.
