N2 - A general multiple-zone model of the gasification reactor of a dual fluidised bed (DFB) gasifier was developed in MATLAB, with the 3D geometry of the reactor considered. The impact of reactor geometry on the product gas composition, pressure profile, and solid distribution was investigated. The model includes both char and tar conversion processes according to a semi-empirical approach from literature. The major homogeneous and heterogeneous gasification reactions were kinetically modelled. A subroutine was developed to implement the kinetics of the reactions and reactor hydrodynamics. An accurate trend of the variation in the product gas composition with gasification temperature was recorded and validated against recent data from literature. The simulation predictions are in very good agreement with the experimental results from three pilot plants with distinct configurations. As a result, the present model can serve as a general tool to analyse common DFB gasifiers, regardless of the configuration.
