项目摘要
A future, environmentally sustainable chemical industry will likely utilize woody biomass as a renewable carbon source. In many biomass conversion processes, chemical reactions in the fluid phase interact with reactions on the surfaces of catalytic materials during forcing conditions of high pressure and elevated temperature. In a recently proposed wood biorefinery, the lignin component of wood is preferentially dissolved and depolymerized to monomers in the fluid phase. Subsequently, the generated monomers need to be stabilized on a catalytic material to avoid formation of undesirable compounds that cannot be further processed. To improve the environmental sustainability and profitability of such a wood biorefinery, this project will accelerate both the lignin depolymerization and the product stabilization by tuning the solvent fluid properties and designing catalysts that are optimized for the reaction environment. Given the complexity of the lignin reductive catalytic fractionation reaction system, it is hardly possible to directly design the catalyst and fluid properties for woody biomass. Because lignin structure varies for different biomass sources, this project will study the coupled homogeneous and heterogeneous processes under realistic reaction conditions for lignin model compounds instead of actual solid biomass. By working with model reactants that contain the critical bond linkages and whose conversion products are representative of the conversion products of woody biomass, the system complexity is dramatically reduced without fundamentally changing the depolymerization and reductive product stabilization chemistry, enabling the concurrent design of fluid properties and catalyst. Overall, this project constitutes a case study of how to use modern data science tools for tightly integrating fundamental computational and experimental research with life cycle assessment, techno-economic analysis, and regular validation of design principles for the conversion of poplar to expedite the development of an environmentally and economically sustainable biorefinery. The education plan includes postgraduate, graduate, undergraduate, and K-12 students. They will be trained in broad research areas while emphasizing the ability to work collaboratively in addressing difficult environmental problems. To engage all team members in unfamiliar fields, students will give tutorial presentations that are aimed at a diverse audience and that can later be adapted into short interactive web-based lectures and web modules on topics such as life cycle assessment and machine learning. Project participants will broaden the participation of underrepresented groups, women, and those with non-traditional backgrounds in science and engineering by engaging in outreach and training programs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
未来,环境可持续的化学工业将可能利用木质生物质作为可再生碳源。在许多生物质转化过程中,在高压和高温的强制条件下,流体相中的化学反应与催化材料表面上的反应相互作用。在最近提出的木材生物炼制中,木材的木质素组分优先溶解并解聚成流体相中的单体。随后,所产生的单体需要在催化材料上稳定,以避免形成不能进一步加工的不期望的化合物。为了提高这种木材生物炼制的环境可持续性和盈利能力,该项目将通过调整溶剂流体性质和设计针对反应环境优化的催化剂来加速木质素解聚和产品稳定化。由于木质素还原催化分馏反应体系的复杂性,很难直接设计木质生物质的催化剂和流体性质。由于木质素结构因生物质来源不同而异,本项目将以木质素模型化合物代替实际固体生物质,在现实反应条件下研究耦合的均相和非均相过程。通过使用包含关键键连接并且其转化产物代表木质生物质的转化产物的模型反应物,系统复杂性显著降低,而不从根本上改变解聚和还原产物稳定化化学,使得能够同时设计流体性质和催化剂。总的来说,该项目是一个案例研究,研究如何使用现代数据科学工具将基础计算和实验研究与生命周期评估、技术经济分析以及白杨转化设计原则的定期验证紧密结合起来,以加快环境和经济可持续生物精炼厂的发展。教育计划包括研究生,研究生,本科生和K-12学生。他们将在广泛的研究领域接受培训,同时强调在解决困难的环境问题方面进行合作的能力。为了让所有团队成员都参与到不熟悉的领域,学生们将提供针对不同受众的教程演示,这些演示后来可以改编成关于生命周期评估和机器学习等主题的简短互动式网络讲座和网络模块。项目参与者将通过参与外展和培训计划来扩大代表性不足的群体、妇女和那些具有非传统背景的科学和工程领域的参与。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
