STTR Phase I: Microwave-Enhanced Modular Ammonia Synthesis

这个小型企业技术转让(STTR)第一阶段项目的更广泛的影响/商业潜力在于它对微波强化氨合成的探索。微波研究具有颠覆性创新的前景，并通过减少能源需求、最大限度地减少直接排放和增加工艺选择性，实现大幅减少碳排放的机会。将微波能应用于化学过程可能会改变化学反应的发生方式。该项目的目标是氨的生产，氨是世界上产量第二大的化学品。氨既是一种肥料，也是一种碳中性液体燃料；它可以在没有二氧化碳(CO2)排放的情况下发电，这使得它对可持续能源至关重要。作为氢的载体，氨在氢动力系统中的作用预计将随着脱碳努力的增加而增加。微波强化氨合成可以满足日益增长的氨需求，打开新的市场机会，并潜在地提高盈利能力，从而改变商业格局。这个STTR第一阶段项目将解决Haber-Bosch工艺，该工艺一个多世纪以来一直是批量生产氨的标准方法。然而，这一过程在高压和高温下运行，需要持续的能源供应，这相当于更高的运营成本和更多的二氧化碳排放。微波通过与以活性中心为目标的电磁辐射相互作用，在多相催化剂表面诱导电子转移，从而提供瞬时、选择性和体积加热。这导致了与传统的热加热、传导加热或对流加热完全不同的反应机理。第一阶段项目的目标将是直接测试特定微波频率的可行性，设计、建模和测试实现高流速、电场均匀、催化剂温度均匀和高电效率的氨特定微波增强型应用器腔的优化。这项研究将包括电磁数值分析、实验室催化活性实验、确定频率效应，以及继续开发微波敏感催化剂和催化剂载体材料。预期的技术成果包括开发一种更高效、可再生能源、成本效益高的氨合成方法，为能源部门的脱碳努力做出贡献。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。

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase I project lies in its exploration of Microwave Enhanced Ammonia Synthesis. Microwave research holds the promise of disruptive innovation and enables opportunities for substantial carbon emission reductions through reduced energy requirements, minimal direct emissions, and increased process selectivity. Applying microwave energy to chemical processes may transform how chemical reactions occur. This project targets the production of ammonia, which is the second most-produced chemical in the world. Ammonia is used as a fertilizer but also as a carbon-neutral liquid fuel; it allows power generation without carbon dioxide (CO2) emissions, making it crucial for sustainable energy. As a hydrogen carrier, ammonia’s role in hydrogen-powered systems is expected to increase with decarbonization efforts. Microwave-enhanced ammonia synthesis can transform the commercial landscape by meeting the increasing demand for ammonia, opening new market opportunities, and potentially increasing profitability.This STTR Phase I project will address the Haber-Bosch process, which has been the standard method to produce ammonia in bulk for over a century. However, this process functions at high pressures and temperatures and requires a constant supply of energy, which equates to higher operational costs and increased emissions of CO2. Microwaves offer instantaneous, selective, and volumetric heating via interaction with electromagnetic radiation that targets the active sites, inducing electron transfer on the surface of a heterogeneous catalyst. This results in a fundamentally different reaction mechanism than conventional thermal heating, conductive, or convective heating. The goal of the Phase-1 project will be to directly test the feasibility of a specific microwave frequency, design, model, and test the optimization of an ammonia-specific microwave-enhanced applicator cavity that implements high flow rates, electric-field uniformity, catalyst temperature uniformity with high electrical efficiency. The research will involve electromagnetic numerical analysis, laboratory catalytic activity experiments, determining frequency effects, and the continued development of microwave-sensitive catalyst and catalyst support material. The anticipated technical results include the development of a more efficient, renewably powered, cost-effective method for ammonia synthesis, contributing to the decarbonization efforts of the energy sector.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.
