摘　　要：秸秆是一种重要的生物质能源,由于其复杂的晶体结构和理化性能,不易直接被生物降解气化,在秸秆沼气生产中要对秸秆进行预处理。通过预处理技术,破坏秸秆的物理质构形式使木质纤维素降解分离,为随后的厌氧消化产气过程提供支撑保障。为此,略述了国内外制备秸秆沼气预处理的基本方法以及相关研究成果概况,探讨了现阶段秸秆生物气化预处理的发展趋势。The straws are important biomass energy resources.It can hardly be biodegraded to produce biogas due to its complicated crystal structure and property of physicochemical.Therefore,the straw should be pretreated in producing biogas.Lignocellulose can be degraded as a simple component by means of the pretreatment technology destructing its physics structure so as to be good for subsequent anaerobic digestion course.This paper summarized relative research progress about different pretreatment methods including physical,chemical and biological method at home and abroad,which discussed the present development trend on pretreatment of straw biogas.
