A reactor model for an oxygen blown bubbling fluidized bed gasifier has been developed to simulate the performance of a pilot plant gasifier. Input data to the model are kinetic parameters for the fixed carbon gasification, pyrolysis yields, steam/oxygen feed rates, bed temperature, and expanded bed height. The algorithm calculate mass and energy balances, e.g., carbon and steam conversions, together with partial pressure profiles for six gas components throughout the bed. The solid phase is assumed to be perfectly mixed, and the gas phase flow is assumed to be nonideal, accounted for by an eddy diffusivity parameter. Due to the particle properties of the shale, e.g., large density and coarse particles, this quite simple approach was shown to give accurate results. The model predictions are compared with experimental data from a 6 ton/day pilot gasifier.
