1336386 (Realff)。该项目旨在创建一个集成系统，利用低温热波动的吸收过程从空气中捕获二氧化碳，该过程将与使用糠醛的酶羧化和空气氧化相结合，以制造2,5呋喃二羧酸（FDCA）。FDCA是聚苯二甲酸乙酯（PET）中使用的对苯二甲酸酯的潜在替代品，因此是生物基聚合物的关键原料。二氧化碳捕获将使用胺功能化的金属有机框架（MOFs）进行。接触器设计是该过程的关键要素，将通过实验和建模来探索气相捕获的单体。解吸将使用蒸汽进行，这将需要MOF？对高浓度的水是稳定的。所使用的酶将由脱羧酶改造而成，这些脱羧酶已被证明具有显著的羧化潜力。过程工程研究将用于确定最有效的过程配置，并建立生命周期能源和大量投入清单。新的耐水胺功能化mof将被合成和表征，这将推动二氧化碳捕获技术的发展。空气捕获循环将用这种材料进行实验演示，这将推动空气捕获系统的艺术状态。新的生物催化剂将被设计成稳定且具有羧基化功能，这将推动生物催化技术的发展。研究小组将设计并优化一个综合系统，利用二氧化碳来制造一种潜在的重要原材料，这将推动绿色化学和材料的发展。PET占聚合物市场份额的18%，是第三大聚合物，因此找到一种可以替代它的可再生材料将对全球产生重大影响。通过C6糖生产乙二醇成分已经是可行的，因此进一步发展的最大障碍是寻找对苯二甲酸盐替代品的途径。基于FDCA的聚合物在饮料容器中具有优越的性能，可口可乐公司已经在探索它们的用途。研究结果将通过公开讲座和科学广播节目广泛传播。参与这项研究的研究生将接受生物催化和材料合成方面的培训，以及集成过程建模和设计元素的概念，这些概念是可持续化学过程发展的基础。

1336386 (Realff). This project seeks to create an integrated system to capture carbon dioxide from air using a sorbent process using low temperature heat swings that will be combined with an enzymatic carboxylation using furfural and air oxidation to make 2,5 furandicarboxylic acid (FDCA). FDCA is a potential replacement for the terephthalates used in poly(ethylene terephthalate) (PET) and hence a key raw material for bio-based polymers. CO2 capture will be carried out using Metal-Organic Frameworks (MOFs) functionalized with amines. Contactor design is a critical element of the process, and monoliths for gas phase capture will be explored both experimentally and through modeling. Desorption will be carried out using steam, which will require MOF?s that are stable to high water concentrations. The enzyme to be used will be engineered from decarboxylases that have been shown to have significant potential for carboxylation. Process engineering studies will be used to identify the most effective process configuration and to establish the life cycle energy and mass input inventories. New water resistant amine functionalized MOFs will be synthesized and characterized that will advance the state of the art in CO2 capture. An air capture cycle will be demonstrated experimentally with this material that will advance the state of the art in air capture systems. New biocatalysts will be engineered that are stable and have carboxylation functionality, which will advance the state of the art in biocatalysis. The research team will design and optimize a combined system for utilizing CO2 to make a potentially important raw material that will advance the state of the art in green chemistry and materials. PET has about 18% of the market share for polymers, the third largest, so finding a renewable source of materials that could replace it would have a substantial global impact. The production of the ethylene glycol component is already feasible through C6 sugars, thus the biggest barrier to further advances is finding routes to the terephthalate replacement. Polymers based on FDCA have superior properties for applications in beverage containers and Coca-Cola is already exploring their use. Results of the research will be widely disseminated through public lectures and a science radio program. Graduate students involved in this research will be trained in the specifics of biocatalysis and materials synthesis, as well as to concepts in integrated process modeling and design elements that underpin development of sustainable chemical processes.
