Fluidised bed gasification is being evaluated by the CSIR as a potential fine coal gasification process for incorporation into future IGCC plants. A suite of four South African coals has been identified as being possible fuels for power stations which would operate for three or four decades, towards the middle of this century.

Despite the increasing need for chemicals and energy, the scenario in which fossil feedstocks can be completely replaced by renewables is currently unrealistic. Thus, the combination of biomass and nonrenewable matrixbased (, coal) technologies could provide a greener way toward the partial substitution of traditional fuels. The hydrogasification of carbonaceous feedstocks (coal and ...

Gasification of biomass for power generation has only been proven in small scales. Most biomass gasification applications demonstrated to date for electric power have power output less than 10 MW (Heschel and Klose 1995). Biomass is also being investigated for cogasification with coal to reduce fossilbased CO 2 emissions.

Conclusion. Fuel gas from gasification may be utilized for power generation after it is properly cleaned in downstream process. The clean fuel gas with high CO and H 2 content has the potential for production of liquid petroleum fuels through FischerTropsch process. However, achieving such clean fuel gas is nowadays a major concern in research.
