In order to study the effects of fluidizing conditions upon the overall rate coefficient of producer gas reaction in the fluidized bed, coke particles both of uniform size and of wide size distribution are gasified with the air, by which the particles are fluidized, and the overall rate coefficient of reduction are obtained.Inner diameters of reactors used are 5.2cm, 5.5cm, 8cm, 11cm, 15.5cm and 25cm respectively.Comparing the overall rate coefficient of reduction with the rate coefficient of chemical reaction, it becomes apparent that the effects of agglomeration or that of turbulent diffusion in fluidized bed are prominent when small particles are gasified at high temperature.<BR>When coke particles with wide size distribution are gasified in steady state, small particles are apt to be elutriated from the fluidized bed by the gas produced, becoming the cause of low carbon efficiency, so the theoretical and experimental studies are performed to analyse the above phenomena, grapsing the kinetics of coke particles in steady state gasification of fluidized bed.
