摘要:

为了去除木质纤维素固有复杂抗性结构,实现木质纤维素原料的高效利用,研究人员不断开发新的木质纤维素预处理技术。低共熔溶剂(Deep Eutectic Solvents, DESs)作为一种绿色溶剂,具有成本低、制备简单、热稳定性好、可设计性等优势,在促进木质纤维素原料预处理、原料酶解转化方面有着较好的应用潜力,得到了研究者们的广泛关注和认可。本研究在查阅国内外研究现状和研究成果的相关报道基础上,综述了氯化胆碱DESs的合成及性质,预处理木质纤维素的作用机理,对木质纤维素酶解效果及转化为生物乙醇的相关研究,指出不同氢键供体、不同的预处理条件对原料的木质素去除率及葡萄糖产量有很大影响,认为DESs预处理木质纤维素极大提高了后续纤维素酶解过程的糖化率,并对DESs预处理机理、循环使用、工艺参数优化方面提出了展望。

Abstract:

In order to remove the inherent complex resistance structure of lignocellulose and achieve efficient utilization of lignocellulose, new lignocellulosic pretreatment technologies have been improved continuously. As green solvents, Deep Eutectic Solvents (DESs) have the advantages of low cost, simple preparation, thermal stability, and designability. They have great application potential in promoting the pretreatment of lignocellulose and enzymatic hydrolysis, and have received widespread attention. Based on the analysis and summary of the research status and achievements at home and abroad, the research progress of synthesis and properties of DESs, pretreatment mechanism, enzymatic hydrolysis, and bioethanol conversion were discussed. It was pointed out that different hydrogen bond donors and different pre-treatment conditions had a significant impact on the lignin removal rate and glucose yield. It was believed that pretreatment of lignocellulose with DESs could greatly improve the saccharification rate. Prospects for DESs pretreatment mechanism, recycling, and process parameter optimization were proposed.
