Abstract

Alternative polymer feedstocks are highly desirable to address environmental, social, and security concerns associated with petrochemical-based materials. Lignocellulosic biomass (LCB) has emerged as one critical feedstock in this regard because it is an abundant and ubiquitous renewable resource. LCB can be deconstructed to generate valuable fuels, chemicals, and small molecules/oligomers that are amenable to modification and polymerization. However, the diversity of LCB complicates the evaluation of biorefinery concepts in areas including process scale-up, production outputs, plant economics, and life-cycle management. We discuss aspects of current LCB biorefinery research with a focus on the major process stages, including feedstock selection, fractionation/deconstruction, and characterization, along with product purification, functionalization, and polymerization to manufacture valuable macromolecular materials. We highlight opportunities to valorize underutilized and complex feedstocks, leverage advanced characterization techniques to predict and manage biorefinery outputs, and increase the fraction of biomass converted into valuable products.

木质纤维素生物炼油厂的工程创新、挑战和机遇:利用生物基聚合物生产。
要解决与石化材料相关的环境、社会和安全问题,替代聚合物原料是非常理想的选择。在这方面,木质纤维素生物质(LCB)已成为一种重要的原料,因为它是一种丰富且无处不在的可再生资源。木质纤维素生物质可通过分解产生有价值的燃料、化学品以及易于改性和聚合的小分子/低聚物。然而,枸杞多糖的多样性使生物精炼概念的评估变得复杂,包括工艺放大、产量、工厂经济性和生命周期管理。我们讨论了当前低浓生物炼制研究的各个方面,重点是主要工艺阶段,包括原料选择、分馏/解构和表征,以及产品纯化、功能化和聚合,以生产有价值的大分子材料。我们强调利用未充分利用的复杂原料的机会,利用先进的表征技术来预测和管理生物炼制的产出,并提高生物质转化为有价值产品的比例。
