The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase II project is to help lessen the environmental burden of climate change by reducing greenhouse gas emissions and dependence on fossil fuels. Climate change is an urgent environmental challenge and to address it, it is essential to provide alternatives to the use of fossil fuels that generate greenhouse gases. Nearly all the jet fuel or aviation fuel in use today is made from crude oil, which is a fossil fuel. This project provides an alternative technology that makes sustainable aviation fuel (SAF) using only carbon dioxide (CO2) captured from waste sources, relatively small volumes of water, and renewable (e.g., solar and wind) electricity. Catalysts are one of the key components of the process that is used to produce this SAF, helping the chemical reactions that produce the fuel occur more efficiently. This project will optimize the catalysts for improved production of SAF. This STTR Phase II project seeks to significantly improve SAF production by developing and characterizing catalysts that convert carbon dioxide (CO2) into the hydrocarbon constituents in sustainable aviation fuels using advanced characterization techniques such as x-ray diffraction, x-ray photoelectron spectroscopy, and electron microscopy. The process will use catalysts as mimics for photosynthesis, taking air (as a CO2 source), water (as a hydrogen source) and sunlight (as an energy source) and converting them into sustainable chemicals and transportation fuels. The only by-products are oxygen and water. Many other related processes often rely on multiple reaction steps to target the same products. This project develops a novel family of proprietary catalysts to convert CO2 to fuels and chemicals in a single step via a direct CO2 hydrogenation process, enabling yields even greater than the theoretical maximum of legacy processes, such as Fischer-Tropsch. This new process eliminates the need for extra intermediate steps that negatively affect process energy demands, emissions, capital and operational cost, and product selling price. The successful outcome of the project will allow significant improvements in production and economics of sustainable aviation fuels.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.

该小企业技术转让 (STTR) 第二阶段项目的更广泛影响/商业潜力是通过减少温室气体排放和对化石燃料的依赖来帮助减轻气候变化的环境负担。气候变化是一项紧迫的环境挑战，为了应对这一挑战，必须提供替代品来替代产生温室气体的化石燃料。当今使用的几乎所有喷气燃料或航空燃料都是由原油制成的，原油是一种化石燃料。该项目提供了一种替代技术，仅使用从废物源捕获的二氧化碳（CO2）、相对少量的水和可再生（例如太阳能和风能）电力来制造可持续航空燃料（SAF）。催化剂是用于生产这种 SAF 的过程的关键组成部分之一，有助于更有效地发生生产燃料的化学反应。该项目将优化催化剂以提高 SAF 的产量。 该 STTR 第二阶段项目旨在通过开发和表征催化剂，使用 X 射线衍射、X 射线光电子能谱和电子等先进表征技术，将二氧化碳 (CO2) 转化为可持续航空燃料中的碳氢化合物成分，从而显着提高 SAF 产量。显微镜。该过程将使用催化剂作为光合作用的模拟物，获取空气（作为二氧化碳源）、水（作为氢源）和阳光（作为能源），并将它们转化为可持续化学品和运输燃料。 唯一的副产品是氧气和水。许多其他相关过程通常依赖于多个反应步骤来靶向相同的产物。该项目开发了一系列新型专有催化剂，通过直接二氧化碳加氢工艺一步将二氧化碳转化为燃料和化学品，其产量甚至高于费托等传统工艺的理论最大值。这种新工艺消除了额外的中间步骤，这些步骤会对工艺能源需求、排放、资本和运营成本以及产品销售价格产生负面影响。该项目的成功成果将显着提高可持续航空燃料的生产和经济性。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和更广泛的影响审查标准进行评估，被认为值得支持。
