A nickel catalyst, for the reforming of hydrocarbons, to produce a hydrogen-rich gas, consists of cylindrical or solid prismatic carriers, having exterior lateral walls which are grooved, in which the spacing, depth and width is such that in relation to a non-grooved cylinder or prism of identical composition, height and size, the gas-solid contact surface is increased while the crush strength is maintained.
