生物质具有可再生性、原料充分和环境兼容性好等优点，生物质能已成为继三大化石能源后的第四大能源，生物质气化是生物质能应用中最有发展前景和最有价值的应用形式。介绍了近年来国内外生物质气化技术研究与应用进展，包括干燥过程、热解过程和氧化还原反应等生物质气化原理，固定床、流化床、气流床、回转窑炉和等离子体炉等气化技术，气化影响因素，气化性能评价和气化发展等。

Because of biomass's renewability,abundance in raw materials,and environmental compatibility,biomass energy has become the fourth largest energy source after three fossil fuels.Biomass gasification is the most promising and valuable application form of biomass energy.This paper introduces worldwide research and application progress in biomass gasification technologies in recent years,including biomass gasification principles about drying process,pyrolysis process and redox reaction,biomass gasification technologies such as fixed bed,fluidized bed,entrained flow bed,rotary kiln and plasma furnace,factors affecting the gasification,gasification performance evaluation and gasification development.
