The utilization of renewable lignocellulosic biomasses for bioenergy synthesis is believed to facilitate competitive commercialization and realize affordable clean energy sources in the future. Among the pathways for biomass pretreatment methods that enhance the efficiency of the whole biofuel production process, the combined microwave irradiation and physicochemical approach is found to provide many economic and environmental benefits. Several studies on microwave-based pretreatment technologies for biomass conversion have been conducted in recent years. Although some reviews are available, most did not comprehensively analyze microwave-physicochemical pretreatment techniques for biomass conversion. The study of these techniques is crucial for sustainable biofuel generation. Therefore, the biomass pretreatment process that combines the physicochemical method with microwave-assisted irradiation is reviewed in this paper. The effects of this pretreatment process on lignocellulosic structure and the ratio of achieved components were also discussed in detail. Pretreatment processes for biomass conversion were substantially affected by temperature, irradiation time, initial feedstock components, catalyst loading, and microwave power. Consequently, neoteric technologies utilizing high efficiency-based green and sustainable solutions should receive further focus. In addition, methodologies for quantifying and evaluating effects and relevant trade-offs should be develop to facilitate the take-off of the biofuel industry with clean and sustainable goals.
利用可再生的木质纤维素生物质来合成生物能源被认为可以促进具有竞争力的商业化，并在未来实现负担得起的清洁能源。在提高整个生物燃料生产过程效率的生物质预处理方法中，发现联合微波辐射和物理化学方法具有许多经济和环境效益。近年来，已经对基于微波的生物质转化预处理技术进行了一些研究。尽管已经有一些综述，但大多数都没有全面分析用于生物质转化的微波-物理化学预处理技术。因此，本文综述了微波辅助辐射与物理化学方法相结合的生物质预处理工艺。还详细讨论了该预处理工艺对木质纤维素结构和获得成分比例的影响。生物质转化的预处理过程受温度、辐照时间、初始原料成分、催化剂负载和微波功率的显著影响。因此，应该进一步关注利用高效、绿色和可持续解决方案的新技术。此外，应该开发用于量化和评估效果及相关权衡的方法，以促进具有清洁和可持续目标的生物燃料产业的腾飞。
