以沼气发酵为目标的木质纤维素预处理方法

摘要

随着化石燃料的日益减少，生物质能技术已成为热门研究课题，而目前厌氧发酵沼气技术也备受瞩目。木质纤维素原料的预处理作为沼气厌氧发酵的关键步骤，已受到广大学者的重视。为此，结合木质纤维素原料的特殊结构特点，从厌氧发酵制沼气这一角度出发，介绍了一些常见的预处理方法，并且对这些方法的作用机理和存在问题进行了简要论述，使其在不同的环境下更好地得以应用。%With the decreasing of fossil fuels , the technology of biomass energy has been very popular , and the technolo-gy of anaerobic fermentation for biogas is also drawed much attention .As a key step for biogas fermentation ,Lignocellulose pretreatment has also received much attention .This paper introduced some popular pretreatment methods for biogas fer-mentation connected with the special structure of lignocellulose .And in order to make these pretreatments well militating under various circumstances , the mechanism of action and some problems of them were elaborated .
