项目摘要

AbstractPI: Jesse Q BondProposal #: 1454346Institution: Syracuse UniversityThis project aims to develop a strategy for producing succinic acid and maleic acid from biomass. Traditionally, these commodity chemicals are made by oxidizing components of crude oil or natural gas, which is challenging. Instead, it may be possible to produce them more efficiently and inexpensively from sugar molecules, which can be extracted from biomass. This approach would require that we understand the reasons why certain catalysts and precursors deliver the desired products, while others do not. We anticipate that a technology that converts biomass and biomass derivatives to valuable products could help with commercial development of biomass processing industries. An educational component of the project will build a connection between Syracuse University students and communities in the city of Syracuse through service projects. The education program includes public workshops designed to improve public scientific literacy by educating participants on topics in energy and resource sustainability. Workshops will also outline effective methods for reducing society?s dependence on fossil resources and technology?s role in sustainability. The workshops will be facilitated by Syracuse University students as part of their undergraduate curriculum. These students will also work on design projects that incorporate new, energy- and resource-efficient technologies into ongoing urban development initiatives. This will allow them to use their training to improve their community and demonstrate the beneficial societal impacts of a STEM education.This award supports the study of gas-phase, aerobic oxidative cleavage of bifunctional levulinic acid (4-oxopentanoic acid) over supported vanadium oxides to yield C4 diacids. Diacid formation occurs through cleavage of the terminal C-C bond in levulinic acid, which is not generally observed in monofunctional ketone analogs, such as 2-pentanone. The central hypothesis is that the structure and bifunctionality of levulinic acid underlie unique interactions with VOx sites that shift selectivity toward terminal C-C cleavage. The project seeks to identify descriptors that govern C-C cleavage selectivity during ketone oxidation.This project will consider the influence of VOx speciation by measuring rates and selectivities of oxidative ketone cleavage over VOx/Al2O3 catalysts in which VOx phase and degree of polymerization are controlled by varying vanadium loading. The roles of Brønsted and Lewis acidity will be examined by studying oxidative cleavage over monolayer VOx/Al2O3 catalysts in which both acid site density and distribution are varied using acidic and basic modifiers. The influence of V-O-X bond character will be probed by comparing VOx sites on oxides that differ in reducibility. Isotopic tracing using 18O will identify the roles of lattice and chemisorbed oxygen during levulinic acid oxidation. Influences of ketone structure, steric interactions, and secondary functionality will be probed through a combination of kinetic and spectroscopic studies that contrast levulinic acid oxidation with that of various mono- and bifunctional ketone analogs. Electronic structure calculations will be used to build and parameterize a microkinetic model, which will reconcile first-principles expectations with experimental outcomes. Raman, UV-Vis, FTIR, and Temperature-Programmed spectroscopies (e.g., TPD, TPSR) will provide comprehensive characterization of site structure and chemical functionality.
摘要PI:Jesse Q BondProposal编号:1454346机构:锡拉丘兹大学该项目旨在开发一种从生物质生产琥珀酸和马来酸的策略。 传统上,这些商品化学品是通过氧化原油或天然气的成分制成的,这是具有挑战性的。 相反,有可能更有效和更便宜地从糖分子中生产它们,糖分子可以从生物质中提取。 这种方法需要我们理解为什么某些催化剂和前体提供所需的产品,而其他人没有。 我们预计,将生物质和生物质衍生物转化为有价值产品的技术可能有助于生物质加工行业的商业发展。该项目的一个教育部分将通过服务项目在锡拉丘兹大学学生和锡拉丘兹市社区之间建立联系。教育计划包括公共研讨会,旨在通过教育参与者关于能源和资源可持续性的主题来提高公众的科学素养。讲习班还将概述减少社会?中国对化石资源和技术的依赖?在可持续发展中的作用。这些讲习班将由锡拉丘兹大学的学生作为本科课程的一部分提供便利。 这些学生还将从事设计项目,将新的能源和资源效率技术纳入正在进行的城市发展计划。 这将使他们能够利用他们的培训来改善他们的社区,并展示STEM教育的有益社会影响。该奖项支持双功能乙酰丙酸(4-氧代戊酸)在负载钒氧化物上气相有氧氧化裂解产生C4二酸的研究。通过乙酰丙酸中末端C-C键的裂解发生二酸形成,这通常在单官能酮类似物如2-戊酮中观察不到。核心假设是乙酰丙酸的结构和双功能性是与VOx位点的独特相互作用的基础,VOx位点将选择性转向末端C-C裂解。该项目旨在确定控制酮氧化过程中C-C裂解选择性的描述符。该项目将通过测量VOx/Al 2 O3催化剂上氧化酮裂解的速率和选择性来考虑VOx形态的影响,其中VOx相和聚合度通过不同的钒负载来控制。通过研究单层VOx/Al 2 O3催化剂上的氧化裂解,将检查布朗斯台德和刘易斯酸性的作用,其中酸性位点密度和分布使用酸性和碱性改性剂。通过比较不同还原性氧化物上的VOx位置,探讨了V-O-X键特征的影响。同位素示踪使用18 O将确定在乙酰丙酸氧化过程中的晶格和化学吸附氧的作用。酮的结构,空间相互作用和二级功能的影响将通过动力学和光谱研究相结合,对比乙酰丙酸氧化与各种单和双功能酮类似物的探索。电子结构计算将被用来建立和参数化的微观动力学模型,这将调和第一原理的期望与实验结果。 拉曼、UV-Vis、FTIR和程序升温光谱(例如,TPD、TPSR)将提供位点结构和化学功能的全面表征。
