This study is devoted to evaluating the performance and the process size of the pressurized dual fluidized bed gasification process that consists of a bubbling bed type of a steam gasifier and a riser type of a partial oxidizer. The sensitivity analysis was conducted by a process simulation to investigate the effect of process parameters of gasification and steam temperatures on the efficiency and the sand circulation flow rate. The result of calculation showed that the efficiency was higher than that of conventional gasifier. The kinetics model of coal gasification with the variables of temperature, steam partial pressure and particle size of coal was also formulated based on the labo-scale experiments. The process simulator and the kinetics model of gasification can decide the process condition and the size of the gasifier.
