Kim (1546647)This is an exploratory, proof-of-concept study aimed primarily at reacting furfuryl alcohol (a major intermediate product of biomass refining) directly to hydrocarbon molecules containing nine to twenty carbon atoms suitable for use as transportation fuels, specifically diesel and jet fuel. Traditional processing is based on catalysis by sulfuric acid. This proposal seeks to demonstrate better performance and product selectivity utilizing supported catalysts while also providing opportunities for improved process efficiency, reduced waste, and a greener environmental footprint. Biomass conversion to useful products is challenged by the broad range of intermediate products produced from the intial pyrolysis of the biomass feedstock together with downstream conversion of the intermediates selectively to high-value fuel and chemical products. Catalysis offers opportunities for facilitating the downstream reactions, but reaction selectivity to desired products is still a challenge and catalyst deactivation is common. This project will provide a direct route for reacting a major intermediate product of biomass refining - furfuryl alcohol - directly to C9-C20 alkanes suitable for transportation fuels, while also providing insight into the mechanism of both the oligomerization reaction and the monomer reaction to cyclopentanone, another commercially important product. The proposal is based on the hypothesis that selectivity toward the targeted alkanes can be markedly improved with respect to the homogeneous acid-catalyzed reaction by using supported heterogeneous catalysts with tunable acidic and basic sites combined with optimized reaction conditions. To this end, the study will screen a broad space of catalyst formulations, reactor design, and operating conditions to enhance C9-C20 product efficiency. The proposed work addresses an important area of research related to energy independence and renewable resources in the form of cellulosic biomass, with potential to produce economic routes to diesel and jet fuel. In parallel, the investigator will also explore conversion of furfuryl alcohol directly to cyclopentanone, a versatile chemical feedstock. Both studies will be conducted in collaboration with Brookhaven National Laboratory to obtain fundamental scientific understanding of relevance to a broad range of catalytic reactions. From an educational standpoint, the project will provide broad catalyst training to one graduate student and an undergraduate researcher, as well as expanding educational outreach programs the investigator has previously established with high school students.

Kim（1546647）这是一项探索性的概念验证研究，主要旨在直接反应富富醇（一种主要的生物质中间产品）与含有九至二十个碳原子的碳氢化合物分子，适合于运输燃料，具体是柴油和喷气燃料。传统加工是基于硫酸催化的。 该提案旨在利用支持的催化剂来表现出更好的性能和产品选择性，同时还提供了提高过程效率，减少废物和更绿色的环境足迹的机会。 生物量转化为有用产品的挑战是由生物质原料的Intial热解产生的广泛的中间产品，以及中间体的下游转化为高价值燃料和化学产品的下游转换。 催化提供了促进下游反应的机会，但是对所需产品的反应选择性仍然是一个挑战，催化剂失活很常见。 该项目将提供直接途径，以直接反应生物质精炼的主要中间产物 - 富叶醇 - 直接与适合运输燃料的C9 -C20烷烃反应，同时还可以深入了解寡聚反应和对环戊酮的单体反应的机制，这是另一个非常重要的产品。该提案基于以下假设：通过使用具有可调的酸性和碱性位点的支持的异质催化剂与优化的反应条件相结合，可以通过使用支持的异质催化剂来显着改善靶向烷烃的选择性。为此，该研究将筛选催化剂配方，反应堆设计和操作条件的广泛空间，以提高C9-C20产品效率。 拟议的工作涉及与能源独立性和可再生资源相关的重要领域，其形式是纤维素生物质的形式，有可能生产柴油和喷气燃料的经济路线。同时，研究者还将探索直接将呋喃醇转化为多功能化学原料环戊酮的转化。这两项研究将与布鲁克黑文国家实验室合作进行，以获得对与广泛催化反应相关性的基本科学理解。 从教育的角度来看，该项目将为一名研究生和一名本科研究人员提供广泛的催化剂培训，并扩大调查人员以前与高中生建立的教育外展计划。
