SBIR Phase I: Hydrogen from Hydrogen Sulfide

这个小企业创新研究（SBIR）项目的更广泛的影响/商业潜力正在推进一项技术，该技术允许在能源部门的许多不同领域中经济有利地减少碳排放。酸性富硫气体通常是生物精炼厂、气体处理设施、石化和燃料精炼厂、垃圾填埋场、纸浆和造纸厂以及废物处理设施等环境中的副产品。所提出的技术具有提供低成本和低碳氢产品的潜力。这种氢可以在当地使用，以取代目前基于化石燃料的氢原料，或作为额外的替代氢产品出售。 该技术有潜力使市场参与者能够实现其积极的碳减排目标，并促进需要氢气作为化学原料或能源的新技术。该SBIR第一阶段项目提出优化基于新型硫碘循环的热化学制氢技术。降低氢制造的碳强度，同时保持生产成本的商业相关性，尽管有很大的兴趣，但仍然难以实现。拟议的项目推进了一种新工艺，与以前的技术相比，该工艺显著降低了能源需求，改善了热集成，并更容易进行工艺流分离。它还利用低价值废物流作为主要原料。技术任务包括通过改变喷嘴配置、填充材料和反应器几何形状来优化气-液接触器的传质质量，准备演示和商业规模的高度详细的工艺和技术经济模型，以及用于含硫伴生气井的中试示范装置的设计-该奖项反映了NSF的法定使命，并被认为是值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估的支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is advancing a technology that allows the economically advantageous reduction of carbon emissions in many different fields of the energy sector. Sour sulfur-rich gases are often a byproduct in settings including biorefineries, gas processing facilities, petrochemical and fuel refineries, landfills, pulp and paper manufacturing, and waste processing facilities. The proposed technology has potential to provide a low cost and low carbon hydrogen product. This hydrogen can be used locally to displace current fossil fuel-based hydrogen feedstocks or sold as an additional alternative hydrogen product. The technology has potential to both enable market incumbents to meet their aggressive carbon emission reduction goals and facilitate new technologies that require hydrogen as either a chemical feedstock or as an energy source. This SBIR Phase I project proposes to optimize a thermochemical hydrogen production technology based on a novel sulfur-iodine cycle. Reducing the carbon intensity of hydrogen manufacturing while keeping production costs commercially relevant has remained elusive despite significant interest. The proposed project advances a new process with significant reductions in energy requirements, improvements in heat integration, and more facile process stream separations compared to predecessor technologies. It also utilizes a low value waste stream as the principal feedstock. Technical tasks include optimizing the mass transfer qualities of the gas-liquid contactor by varying nozzle configuration, packing material, and reactor geometry, preparing a highly detailed process and techno-economic model at both the demonstration and commercial scale, and the design of a pilot demonstration unit for use at a sour associated gas well-site.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.
