	%X The adsorption properties of CO and H2 on iron-based
catalyst with addition of Zr and Ni were investigated using
temperature programmed desorption process. It was found that on the
carburized iron-based catalysts, molecular state and dissociative state
CO existed together. The addition of Zr was preferential for the
molecular state adsorption of CO on iron-based catalyst and the
presence of Ni was beneficial to the dissociative adsorption of CO. On
H2 reduced catalysts, hydrogen mainly adsorbs on the surface iron
sites and surface oxide sites. On CO reduced catalysts, hydrogen
probably existed as the most stable CH and OH species. The addition
of Zr was not benefit to the dissociative adsorption of hydrogen on
iron-based catalyst and the presence of Ni was preferential for the
dissociative adsorption of hydrogen.
