摘要
木质纤维素生物质是缓解全球变暖的可行解决方案之一。然而,生物质的有限利用主要集中在纤维素和半纤维素上,限制了经济和环境的可行性。为了应对这一问题,我们提出了一种从生物质中与四氢呋喃和己二酸共同生产 1,6- 己二醇(1,6-HDO)的综合工艺,称为策略 A。为了比较木质素升级和原料的影响,我们采用了策略 B(单独与四氢呋喃共同生产)和策略 C(从化石燃料中生产 1,6-HDO 的传统路线)。通过技术经济分析确定最低销售价格,评估了战略 A 的市场竞争力;通过中点和终点生命周期评估(LCA)量化环境影响,深入研究了可持续性。结果发现,战略 A 在经济效益(3,402 美元/吨)和环境效益(-26.9 千克二氧化碳当量)方面都最为有利。这表明,木质素价值化不仅在经济上有利,在环境上也是可取的。最后,利用敏感性和不确定性分析研究了经济、工艺和环境参数对经济和环境可行性的影响。这些分析结果为生物基化学品生产提供了宝贵的见解。
Maximizing biomass utilization: An integrated strategy for coproducing multiple chemicals
Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol (1,6-HDO) with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments (LCAs). Strategy A was found to be the most favorable both economically (US$3,402/ton) and environmentally (−26.9 kg CO2 eq.). This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.
