Fe-Ce/dolomite catalyst was prepared by the impregnation method, and the catalyst was characterized by SEM and XRD. The hightemperature water vapor catalytic gasification test was carried out on a selfbuilt fixedbed gasification furnace test station, and the content of the auxiliary agent was studied. The effect of the gasification temperature and other factors on the gasification characteristics of the water vapor of pine rod and effect of number of times of catalyst on deposition of gas component and catalyst were researched. The experimental results showed that the auxiliary Fe and Ce can be well supported on the dolomite, and the catalyst gasification effect of the assistant content of 8% Fe-2% Ce was good. Fixed the catalytic temperature, and the catalyst was used for making the pine wood rod at different temperatures. In the steam gasification test, when the temperature was increased from 750℃ to 950℃, the gas production rate and hydrogen production rate were increased from 1.05m3/kg and 31.67g/kg at 750℃ to 1.56m3/kg and 65.39g/kg at 900℃, respectively. Compared with the gasification test without catalyst, the hydrogen production rate was increased by 0.15m3/kg and 16.27g/kg, and the hydrogen volume fraction was increased from 39.02% to 46.95%, respectively. The third gasification test of the catalyst was carried out at 800℃. The volume fraction of hydrogen was decreased from 40.34% in the first time to 38.97% in the second time and 34.95% in the third time. The amount of carbon deposition was increased from the first time of 21.55mg/g to the third time of 31.61mg/g.
