Hemicellulose-rich lignocellulosic biomass is an ideal source of carbohydrates to produce furfural commercially. Furfural is recognized as a versatile platform chemical with a bright future in many industries, which can be obtained from the hemicellulose fraction via acid hydrolysis followed by recovery and, lastly purification through a distillation system. This review provides a critical analysis of the recent progress of industrial furfural production from lignocellulosic biomass worldwide. Although old-fashioned process technologies are well established and adopted widely, many novel technologies have emerged to overcome several drawbacks that induce sustainability challenges as well as fully utilize other lignocellulosic components, including cellulose and lignin. Furfural forms the natural precursor for many furan-based derivatives that are vital in the biochemicals and biofuels manufacturing sector, with furfuryl alcohol being the most prominent downstream product. Corn cobs and sugarcane bagasse are the most commonly used raw materials by furfural manufacturing companies on a commercial scale. Furfural market analysis is also performed to study the ongoing economic trends. Techno-economic analyses of furfural production are reviewed to provide insights and strategies on improving furfural production. These topics are reviewed, as well as the future technology development opportunities, including extraction techniques using supercritical fluid, the application of green solvent, and the use of heterogeneous acid catalyst to enhance furfural production.

富含半纤维素的木质纤维素生物质是商业化生产糠醛的理想碳水化合物来源。糠醛被认为是一种多功能平台化学品，在许多行业中具有光明的前景，它可以通过酸水解从半纤维素馏分中获得，然后进行回收，最后通过蒸馏系统进行纯化。本综述对全球木质纤维素生物质工业糠醛生产的最新进展进行了批判性分析。尽管老式工艺技术已经成熟并被广泛采用，但已经出现了许多新技术来克服导致可持续性挑战的几个缺点，并充分利用其他木质纤维素成分，包括纤维素和木质素。糠醛是许多呋喃衍生物的天然前体，这些衍生物在生化和生物燃料制造领域至关重要，糠醇是最突出的下游产品。玉米芯和甘蔗渣是糠醛制造公司在商业规模上最常用的原材料。还进行糠醛市场分析以研究当前的经济趋势。回顾了糠醛生产的技术经济分析，以提供改善糠醛生产的见解和策略。回顾了这些主题以及未来的技术发展机会，包括使用超临界流体的萃取技术、绿色溶剂的应用以及使用非均相酸催化剂来提高糠醛生产。
