Research progress of biomass gasification technology

As one of the important methods of clean and efficient exploitation of biomass, the biomass gasification technology has a broad development prospects. The domestic and abroad advances of biomass gasification technologies in recent years, such as gasifying agent gasification，pyrolysis gasification, catalytic gasification, plasma gasification, ultra supercritical water gasification, etc. were reviewed in the paper. Tar removal and purification, and the preparation of efficient catalysts are regarded as the two biggest obstacles to the biomass gasification, and the removal of tar by chemical method and the development of compound catalysts are suitable solutions to these problems. Finally, the large scale commercial utilization in certain industries is forecasted to be the main development trend of the biomass gasification.
