The double-effect Ni-based catalysts, modified with Ce, Mg, and Fe synthesized by the coprecipitation method, were applied into enhanced steam reforming process of real tar. effects catalysts different doping mass proportions (3, 6, 9, 12%) on H 2 yield, CO concentrations studied. results revealed that tar efficiency was improved appropriate additives added. Ce- or Mg-doped catalyst could change distribution morphology active component Ni. 6% Ce 3% Mg showed best catalytic activity in experiment, yield reaching 86.84% 85.22%, respectively. Fe-doped form an Ni–Fe alloy improve stability catalyst, better can be obtained at 9 12% doping, 85.54 85.80%,
