Fluidized Bed Gasification of Coal/biomass Slurries

The paper deals with the setup of a fluidized bed facility for gasification of valuable fuel slurries. A wet biomass residue, Indonesian coal and rape seed oil were used for the preparation of a stable slurry having a water content of around 45% by mass. A preliminary test of gasification was successfully carried out at 800 °C with generation of a gas having a moderate content of H2, CO and CH4. The comparison with computed data of a thermodynamic equilibrium model shows that the conversion of the slurry can be improved by optimization of operating conditions and reduction of the water content in the slurry.
