生物质气化技术研究进展

Research progress of biomass gasification technology

生物质气化技术是生物质洁净高效利用的重要方法,具有广阔的发展前景。本文综述了近年来国内外生物质气化技术中气化剂气化、热解气化、催化气化、等离子体气化、超临界水气化等方法的研究进展。认为目前生物质气化技术需要重点解决的主要难题是焦油脱除和净化以及高效催化剂的制备,化学法除焦和开发复合型催化剂是解决这些难题的有效方法,生物质气化技术的大规模商业化利用是未来的发展方向。

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 largescale commercial utilization in certain industries is forecasted to be the main development trend of the biomass gasification.
