摘要
介绍了生物质中纤维素、半纤维素及木质素的结构及各组分分离方法,重点对组分分离方法的优点及缺点进行了综述。指出为实现生物质资源替代日益紧缺的化石资源,首先要解决的是生物质各组分的高效、绿色、经济分离;其次需将生物质组分分离与后续高值化应用工艺进行耦合,以实现生物质精炼。
The structure of cellulose,hemicellulose and lignin in biomass and their separation methods were introduced,and advantages and disadvantages of the mentioned components′separation methods were summarized.It was pointed out that in order to achieve the replacement of biomass for the increasingly scarce fossil resources,the first thing that needed to be solved was the efficient,green and economical separation of biomass components.Secondly,it was necessary to couple the separation of biomass components with the subsequent high-value application process,so as to realize the refining of biomass.
