The applications of green chemistry and industrial bioprocessing are becoming more popular to address concerns of pollution, climate change, global warming, circular bioeconomy, sustainable development goals and energy security. Both biological and thermochemical routes can play vital roles in transforming waste lignocellulosic biomass to high-value bioproducts. Lignocellulosic biomass contains essential building blocks that could be tapped to generate biofuels, biochemicals and biomaterials to replace petroleum-derived fuels and chemicals. Besides containing extractives and ash, lignocellulosic feedstocks are made up of cellulose, hemicellulose and lignin typically in the ranges of 35–55 wt%, 20–40 wt% and 10–25 wt%, respectively. Catalytic thermochemical approaches are effective for biomass conversion with a significant yield of various platform chemicals, such as furfural, 5-hydroxymethylfurfural, levulinic acid and other furan or non-furan-based chemicals. These chemicals play a crucial part in the synthesis of different fuel-based materials, which can successfully replace petroleum-based chemicals or fuels. Lignocellulosic biomass and their derived monomeric sugars can be catalytically converted into various platform chemicals using different homogeneous and heterogeneous catalysts. In this review paper, we have highlighted some promising catalysts such as mineral acids, mesoporous silica materials, zeolites, metal–organic frameworks, metal oxides and ionic liquids used in biorefining to generate biochemicals. We have also reviewed a few pieces of notable literature presenting the catalytic conversion of cellulose, hemicellulose, cellobiose, glucose, fructose and xylose into various high-value chemicals.

木质纤维素多糖催化转化为商品生化产品:综述
绿色化学和工业生物加工的应用越来越受欢迎,以解决污染、气候变化、全球变暖、循环生物经济、可持续发展目标和能源安全等问题。生物和热化学途径都可以在将废弃的木质纤维素生物质转化为高价值生物产品方面发挥重要作用。木质纤维素生物质包含基本的构建模块,可以利用这些构建模块来生产生物燃料、生物化学品和生物材料,以替代石油衍生的燃料和化学品。除了含有提取物和灰分外,木质纤维素原料还由纤维素、半纤维素和木质素组成,通常分别占 35-55 重量%、20-40 重量%和 10-25 重量%。催化热化学方法对生物质转化有效,各种平台化学品的产量显着,例如糠醛、5-羟甲基糠醛、乙酰丙酸和其他呋喃或非呋喃类化学品。这些化学品在不同燃料基材料的合成中起着至关重要的作用,可以成功替代石油基化学品或燃料。木质纤维素生物质及其衍生的单糖可以使用不同的均相和非均相催化剂催化转化为各种平台化学品。在这篇综述论文中,我们重点介绍了一些有前景的催化剂,如无机酸、介孔二氧化硅材料、沸石、金属有机骨架、金属氧化物和用于生物精炼以产生生化产品的离子液体。
