【摘要】：木质素主要由羟基或甲氧基取代的苯丙烷基结构组成,是自然界中唯一可大量生产芳香族化学品的可再生原料。通过选择合适的催化剂,打断其长链结构,高选择性地获得某种或某类目标产物是木质素综合利用的重要途径。金属硫化物催化剂由于具有良好的加氢及脱氧活性,几十年来被广泛应用于木质素催化转化领域。本文对金属硫化物催化剂在木质素及其模型化合物催化转化中的应用进行了综述,从活性组分、载体材料、反应条件及反应机理等方面进行了总结和分析。在此基础上,指出了金属硫化物催化剂在木质素催化降解中面临的难题,并对未来研究提出了建议与展望。
[Abstract]:Lignin is mainly composed of hydroxyl or methoxy substituted phenylpropyl alkyl. Lignin is the only renewable raw material which can produce aromatic chemicals in large quantities in nature. The long chain structure of lignin is broken by selecting suitable catalyst. It is an important way for lignin to obtain some target products with high selectivity. Metal sulphide catalysts have good hydrogenation and deoxidation activity. In recent decades, it has been widely used in the field of lignin catalytic transformation. In this paper, the application of metal sulfide catalysts in the catalytic transformation of lignin and its model compounds is reviewed, from active components to support materials. The reaction conditions and reaction mechanism were summarized and analyzed. On the basis of this, the problems of metal sulphide catalyst in lignin catalytic degradation were pointed out, and suggestions and prospects for future research were put forward.
