摘要
纤维素是自然界储量最为丰富的生物质原料,工业上以高纯度溶解浆为纤维素原料可以制备不同的再生纤维素材料(纤维和薄膜)和纤维素衍生物(酯、醚),在现代工业和人们生活中具有广泛的应用。需要指出的是目前工业上使用的都是高纯度的纤维素原料,成本较高。另一方面,自然界存在大量低成本的纤维素原料,如农业秸秆。而开发高效、绿色的加工方法将这些低成本的纤维素原料转化为高附加值的制品是至关重要的。本报告将介绍我们在此领域的相关研究进展。
Cellulose is the most abundant renewable organic material with a host of current and potential uses. Starting with dissolving pulp as a purified raw material, cellulose is converted industrially into regenerated materials(fibers, films, food casings, membranes, sponges, etc.) and cellulose derivatives(ethers and esters). However, until now, the main source for commercial cellulose production are concentrates on the highly pure cellulose sources such as cotton linters and dissolving wood pulp. This fact makes the raw materials expensive to obtain. In contrast, the low-grade lignocellulosic biomass has become attractive as a renewable resource because it is available in large quantities and routinely widely cultivated in the world. At present, development of new and effective methods to convert low-grade cellulose into high value products is critical. In this talk, I would like introduce our research progress in this field.
