ABSTRACT:
For shortening the starting time of an autothermal reformer, the autothermal reformer is started by a method comprising: a first preheating step of heating a reforming catalyst up to a predetermined temperature with use of heating means, the heating means being positioned upstream of the reforming catalyst to heat the reforming catalyst; a second preheating step of stopping the heating after arrival at the predetermined temperature, feeding vaporized fuel and air to the reforming catalyst at the predetermined temperature, allowing the fuel to be oxidized by the reforming catalyst and thereby heating the reforming catalyst; and a starting step of also supplying steam to the reforming catalyst heated by the second preheating step and starting autothermal reforming under the condition for a steady state.
