Abstract: This invention discloses a high temperature stable supported non-noble metal catalyst, represented by a general formula: NiCoaCebMgcYdOx(y)/S wherein, S is a low surface area macroporous highly sintered solid support essentially comprising zirconium and hafnium oxides with less than 3 wt % silica and/or alumina and having surface area less than 1.0 m2/g and pore diameter greater than 0.1 micron, in a form of pellet, ring, monolith or granules; Ni, Co, Ce, Mg, Y and O are nickel, cobalt, cerium, magnesium, yttrium and oxygen, respectively; a is Co/Ni mole ratio in the range from 0.01 to 10; b is Ce/Ni mole ratio in the range from 0.001 to 10; c is Mg/Ni mole ratio in the range from 0.001 to 10; d is Y/Ni mole ratio in the range from 0.005 to 5; x is number of oxygen atoms required to fulfil the valance requirement of the metallic elements, NiCoaCebMgcYd; and y is weight percent loading of the active catalyst mass, NiCoaCebMgcYdOx, on the support, S, in the range from 0.
