Selective Conversion of Carbohydrate/Derived Chemicals Over Supported Metal Catalyst

提案标题：碳水化合物衍生化学品在负载型金属催化剂上的选择性转化提案编号：CTS-0102307主要调查者：James Dumesic研究所：威斯康星大学这项提案的目的是将碳水化合物衍生化学品转化为生产商品化学品。碳水化合物发酵产生的乳酸可以进一步加工，用于生产可生物降解的聚合物、1，2-丙二醇、乳酸乙酯、丙烯酸和丙烯酸酯等商品化学品。发酵过程和选择性催化过程的结合为从可再生碳水化合物原料而不是从不可再生石油来源生产这些商品化学品提供了一条清洁的路线。在以前的工作中，铜基催化剂体系表现出100%的乳酸转化率，高选择性地合成所需的1，2丙二醇。将对含氧碳氢化合物(羟基酸、有机酸、醇和醛)在铜基材料和过渡金属基材料上的相互作用进行基础研究。该计划将结合微量热测量、反应动力学研究、光谱研究和密度泛函理论计算来阐明轻氧化化合物在负载型金属催化剂上的反应路径。总体而言，这项工作有可能加强可再生生物来源生产的化学品的商业化。

Proposal Title: Selective Conversin of Carbohydrate-derived Chemicals over Supported Metal CatalystsProposal Number: CTS-0102307Principal Investigator: James DumesicInstitution: University of WisconsinThe objective of this proposal is to convert carbohydrate-derived chemicals for the production of commodity chemicals. Lactic acid produced from the fermentation of carbohydrates may be further processed for the production of commodity chemicals such as biodegradable polymers, 1,2-propanediol, ethyl lactate, acrylic acid, and acrylates. The combination of fermentation processes and selective catalytic processes provides a clean route for the production of these commodity chemicals from renewable carbohydrate feedstocks instead of from non-renewable petroleum sources. In previous work copper-based catalyst systems exhibited 100% conversion of lactic acid with high selectivity to the desired 1,2 propanediol. Fundamental studies of the interactions of oxygenated hydrocarbons (hydroxy acids, organic acids, alcohols, and aldehydes) over copper-based materials and over transition-metal-based materials will be conducted. The plan is to combine microcalorimetric measurements, reaction kinetics studies, spectroscopic investigations, and density functional theory calculations to elucidate pathways for reactions of light oxygenated compounds over supported metal catalysts. Overall, this work has the potential to enhance the commercialization of chemicals produced from renewable biological sources.
