Kinetic studies on char partially gasified in the fixed-bed were carried out on the thermogravimetric analyzer.The effects of char type，temperature and the gasification conversion in the fixed-bed on the kinetic parameters and the stage characteristics of gasification are discussed in this paper.Results indicate that the reactant gas-steam could activate the char.With the increase of the gasification conversion in the fixed-bed，the activation energy and the pre-exponental factor decrease，effect of the pressure of steam to gasification rate decreases(there is sometime increase of Wangfeng char at low gasification conversion).For different char types，the effects of gasification conversion in the fixed-bed on the reaction rate constant are different.Char type and temperature are important factors affecting the gasification rate.At the same time，they can also affect seriously the stage characteristics.
