综述了木质纤维素类生物质废弃物的物理、化学和组合物理化学预处理方法，并对木质纤维素类生物质废弃物的处理方法进行了综述。对木质纤维素废物在用于能源或液体燃料的高级热化学处理中的适用性的相关文献进行了仔细审查。通过改变木质纤维素生物质废物的整体天然存在的生物聚合物基质，单个组分如纤维素、半纤维素和木质素可以用于许多下游工艺，如热解、气化和催化升级为增值产品如低碳能源。评估合适的木质纤维素预处理技术对于适应小型和大型操作的下游工艺至关重要。必须考虑到操作工艺的成本（温度、压力或能源限制）、预处理后原料的物理和化学结构（分解/降解、去除无机成分或有机物溶解）或扩大预处理工艺的能力，以便揭示生物可再生废物的真正价值。
Various methods of physical, chemical and combined physicochemical pre-treatments for lignocellulosic biomass waste valorisation to value-added feedstock/solid fuels for downstream processes in chemical industries have been reviewed. The relevant literature was scrutinized for lignocellulosic waste applicability in advanced thermochemical treatments for either energy or liquid fuels. By altering the overall naturally occurring bio-polymeric matrix of lignocellulosic biomass waste, individual components such as cellulose, hemicellulose and lignin can be accessed for numerous downstream processes such as pyrolysis, gasification and catalytic upgrading to value-added products such as low carbon energy. Assessing the appropriate lignocellulosic pre-treatment technology is critical to suit the downstream process of both small- and large-scale operations. The cost to operate the process (temperature, pressure or energy constraints), the physical and chemical structure of the feedstock after pre-treatment (decomposition/degradation, removal of inorganic components or organic solubilization) or the ability to scale up the pre-treating process must be considered so that the true value in the use of bio-renewable waste can be revealed.
