The steam gasification behavior and kinetics of coal char fines derived from fluidized bed gasifier were investigated by TGS-2 thermogravimetric analyzer. Their physical and chemical properties were also compared with the corresponding coal chars and demineralized char fines. The results show that the gasification reactivity of char fines increase with increasing temperature. Compared with the coal char from pyrolysis, the char fine has a larger surface area and leads to a higher gasification reactivity. The reactivity of different coal char fines are also affected by their carbon crystalline structure and ash content. Based on this, the gasification reactions are described by the shrinking core model and the kinetic parameters are obtained, so as to provide some theoretical guides for the gasification of coal char fines.
