MODEL-BASED INVESTIGATION OF BIOMASS GASIFICATION IN A FLUIDIZED BED REACTOR

The present work concerns with Computational Fluiddynamics modelling of biomass gasification in a fluidized bed reactor, where a dispersed phase, consisting of solid particles, is fluidized by air (fluid phase) and transported upwards through a vertical riser. The main aims of the mathematical model were to optimize the reactor geometrical key parameters (diameter and length of bed, diameter and shape of the dispersed phase, etc,) by parametric analysis, investigating the impact of gasifier temperature and air supply in order to identify the best fluidized bed configuration for the conversion of a typical lignocellulosic biomass into hydrogen rich syngas.
