Abstract

Excessive dependence on fossil resources to supply the increased energy demands has led to unsustainable growth. Hence, there is a necessity to shift our reliance from non-renewable to renewable resources. In this scenario, lignocellulosic biorefinery gains its importance because lignocellulosic biomass can be converted into various value-added products. However, biomass pretreatment is necessary due to the recalcitrant nature of the biomass. Various pretreatment techniques are employed to convert biomass into a more amenable structure to be utilized in the further steps of biorefinery. Hence, this review concentrates on different chemical pretreatment techniques used currently on biomass along with their modes of action on the biomass. This review will provide a detailed concept of various chemical pretreatments and the recent developments in pretreatment techniques. Despite this, the limitations of the current pretreatment strategies and the difficulties in their industrial applications are also discussed, which could provide innovative ideas to overcome these issues.

木质纤维素生物质化学预处理制备生物制品的研究进展:机理、挑战与应用

过度依赖化石资源来满足日益增长的能源需求，导致了不可持续的增长。因此，有必要将我们对不可再生资源的依赖转向可再生资源。在这种情况下，木质纤维素生物炼制获得其重要性，因为木质纤维素生物质可以转化为各种增值产品。然而，由于生物质的顽固性，预处理是必要的。采用各种预处理技术将生物质转化为更适于在生物炼制的进一步步骤中使用的结构。因此，本文综述了目前生物质化学预处理技术及其对生物质的作用方式。本文将详细介绍各种化学预处理的概念和预处理技术的最新进展。尽管如此，本文还讨论了当前预处理策略的局限性及其在工业应用中的困难，为克服这些问题提供了创新思路。
