中文摘要:
      半纤维素含量丰富,应用前景广阔。但半纤维素结构复杂多样,实现其高值化利用是一个长期存在的挑战。采用单一物理法、化学法或生物法预处理提取半纤维素时,在能耗、成本、效果等方面均存在一定局限性。联合预处理可结合各种预处理方法的优势,降低单一预处理的局限性,已成为目前半纤维素提取的研究热点。本文综述了木质纤维中半纤维素的联合预处理提取工艺,如超声辅助、微波辅助、酸/水热处理和碱/水热处理等,并简要介绍了各种预处理方法的优缺点,以期为半纤维素的提取及应用提供理论指导。
Abstract:
      Hemicellulose is rich in content with broad application prospects. However, the structure of hemicellulose is complex and diverse, and its high-value utilization is a long-standing challenge. When a single physical, chemical or biological pretreatment was used to extract hemicellulose, there were some limitations in terms of energy consumption, cost and effect. Combined pretreatment could combine the advantages of various pretreatment methods and reduce the limitations of single pretreatment. Thus, combined strategy method had become the current research hotspot for hemicellulose extraction. This paper reviewed the combined pretreatment extraction process of hemicellulose in the wood fiber, such as ultrasound-assisted, microwave-assisted, acid-water heat treatment and alkaline-water heat treatment, etc., and briefly described the advantages and disadvantages of the various pretreatment methods, with a view to providing theoretical guidance for the extraction and application of hemicellulose.
