摘　　要：表面活性剂广泛应用于各个领域,在制备纤维素乙醇过程中添加非离子表面活性剂,研究发现,非离子表面活性剂对木质纤维素原料的预处理和水解过程都产生积极的作用,同时总结了针对不同的木质纤维素原料可以起促进作用的非离子表面活性剂。探讨了非离子表面活性剂在水解过程中对木质纤维素原料结构以及对纤维素酶的影响,着重从纤维素酶的扩散及吸附两个方面阐述了非离子表面活性剂对纤维素酶的影响机制。Surfactant is widely used in various fields at present. In the preparation of cellulosic ethanol, the addition ofnonionic surfactant could promote the pretreatment and the hydrolysis of lignocellulosic biomass. In this paper, nonionic surfactant promoting the hydrolysis of different lignocellulosic biomass were introduced, and the effects of nonionic surfactant on the structure of lignocellulose materials and cellulase in hydrolysis process were investigated. The influencing mechanism ofnonionic surfactant on cellulase was elaborated from diffusion and absorption.
