项目摘要

The development of catalytic routes for converting lower alkanes to olefins is a challenging problem with high potential payoff due to the vast shale gas resources that have recently become available. The overarching goal of this project is to revolutionize propylene production from alkanes through an innovative tandem catalytic reaction scheme that improves overall conversion and selectivity. The project is based on a potentially transformative approach where new paradigms in reaction mechanisms guide catalyst synthesis. A hierarchical framework will be developed for rational design and characterization of catalysts with significant potential broader impact in the energy, petrochemical and chemical sectors of the US industry.The main objective of this project is to develop a new class of bifunctional catalysts based on sub-stoichiometric nanophase metal oxides that will work in a tandem reaction scheme, where oxidative dehydrogenation of alkanes and carbon dioxide reduction, via dissociative adsorption, will occur simultaneously without producing syngas. The proposed novel tandem reaction scheme has the potential to intensify on-purpose propylene production by preventing side reactions, such as coke formation, and further aromatization of propylene. A new facile synthesis method for producing oxygen-deficient anatase nanosheet catalysts is proposed by utilizing highly amorphous solubilized cellulose as a sacrificial template. The proposed experimental framework is based on optical reactor prototyping and Operando spectroscopy, where the molecular structure and reactivity of the metal oxide catalysts are studied simultaneously in a single optical cell by time- and spatially-resolved Raman spectroscopy under real working conditions. Integration of research and education is focused towards modernizing the chemical reaction engineering curriculum with teaching modules on Operando spectroscopy. Outreach efforts are aimed at engaging K-12 students, including underrepresented minorities, by developing a freeware computer game that teaches principles of molecular symmetry and spectroscopy.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.
由于最近出现了大量的页岩气资源,开发将低级烷烃转化为烯烃的催化路线是一个具有挑战性的问题,具有很高的潜在回报。该项目的总体目标是通过创新的串联催化反应方案,提高整体转化率和选择性,彻底改变烷烃生产丙烯的方法。该项目基于一种潜在的变革性方法,其中反应机制的新范例指导催化剂合成。将开发一个分层框架,用于合理设计和表征催化剂,这些催化剂对美国工业的能源、石化和化学领域具有重大潜在更广泛的影响。该项目的主要目标是开发基于子功能的新型双功能催化剂。化学计量的纳米相金属氧化物将在串联反应方案中发挥作用,其中烷烃的氧化脱氢和二氧化碳的还原通过解离吸附同时发生,而不产生合成气。所提出的新型串联反应方案有可能通过防止副反应(例如焦炭形成和丙烯的进一步芳构化)来强化丙烯的生产。提出了一种利用高度非晶态可溶纤维素作为牺牲模板来生产缺氧锐钛矿纳米片催化剂的新简便合成方法。所提出的实验框架基于光学反应器原型和操作光谱,其中金属氧化物催化剂的分子结构和反应性在单个光学单元中通过实际工作条件下的时间和空间分辨拉曼光谱同时研究。研究和教育的整合重点是通过操作光谱学教学模块实现化学反应工程课程的现代化。外展工作旨在通过开发一款教授分子对称性和光谱学原理的免费软件计算机游戏,吸引 K-12 学生,包括代表性不足的少数族裔。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力优势进行评估,被认为值得支持以及更广泛的影响审查标准。
