The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is in removing sulfur compounds from various fuels such as diesel, gasoline and mixture of refined fuels known as transmix. It is critically important to reduce sulfur levels below 10 ppm as the emissions from transportation vehicles can cause acid rain and associated undesired effects. Sulfur removal from fuels is even more critical for implementation of fuel cell technologies due to fuel reformer catalyst poisoning at sulfur levels as low as 1 ppm or below. Finally, there is a need for sulfur-tolerant catalysts and sulfur removal processes in value added chemical production using bio-derived and fossil derived fuels. The global market for hydro-desulfurization catalysts in the transportation fuel segment is estimated at over $1B and growing fast. The company's proposed catalyst could address a market size of $150-200M/yr or more. It may find additional applications in commercial markets in ultra-low sulfur diesel, fuel reformer technology and sulfur tolerant catalysts. The development of a scalable manufacturing method for advanced materials undertaken in this project will contribute to U.S. competitiveness and strengthen Cleantech and energy sectors in the state of KY. This project addresses the development of high performance catalysts needed for the removal of sulfur from hydrocarbon fuels. However, sulfur removal at concentrations below 50 ppm is difficult due to the presence of hetero-cyclic thiophenic species. During Phase I, the company developed a catalyst product and demonstrated its performance in terms of ultra-deep hydrodesulfurization activity, reducing sulfur levels from 200 ppm to much lower than 1 ppm in a variety of fuels. Phase II studies will allow optimization of the catalysts for hydrodesulfurization activity and mechanical properties. Catalysts with bi-functional activity toward aromatics hydrogenation and hydrodesulfurization will reduce several process steps, thereby reducing the costs involved in hydroprocessing of fuels. Phase II studies will enable development of a process for scalable production of nanowires. The fundamental insight from the performance can be extended toward designing various high performance catalysts using nanowire supports. Some beneficial effects using nanowire supports include unique active metal/support interactions; single crystal surfaces for uniform morphologies for active metals and their alloys and management of active sites. Specifically, in the case of hydrodesulfurization, nanowire supports provided an easier diffusion pathway for sulfur transfer to maintain active metal sites for desulfurization activity.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力在于去除各种燃料的硫化合物，例如柴油，汽油和精制燃料的混合物，称为Transmix。将硫水平降低到10 ppm至关重要，因为运输车辆的排放会导致酸雨和相关的不良影响。从燃料中去除硫对于在低至1 ppm或以下的硫水平上的燃料改革催化剂中毒而导致的燃料电池技术更为重要。最后，需要使用生物衍生和化石衍生的燃料在增值化学产生中耐硫化催化剂和硫的去除过程。运输燃料领域的全球水力硫化催化剂市场估计超过1B美元，并且增长迅速。该公司拟议的催化剂可以解决每年150-2亿美元或更长时间的市场规模。它可能会在超低硫柴油，燃料改革仪技术和硫耐催化剂中找到其他应用。该项目中采用的高级材料的可扩展制造方法的开发将有助于美国的竞争力，并加强肯塔基州的清洁技术和能源部门。该项目解决了从碳氢化合物燃料中去除硫所需的高性能催化剂的发展。然而，由于存在异偶然硫代苯基物种，很难以低于50 ppm的浓度去除硫。在第一阶段，该公司开发了一种催化剂产品，并在超深氢硫化活性方面展示了其性能，在各种燃料中，硫水平从200 ppm降低到低于1 ppm。第二阶段的研究将允许优化催化剂用于氢化硫化活性和机械性能。具有对芳香族化氢化和氢化化的双功能活性的催化剂将减少几个过程步骤，从而降低燃料的水合处理成本。第二阶段的研究将使纳米线的可扩展生产过程开发。性能的基本见解可以扩展到使用纳米线支持设计各种高性能催化剂。使用纳米线支持的一些有益效果包括独特的活性金属/支撑相互作用；活性金属及其合金和活性位点的合金的均匀形态的单晶表面。具体而言，在氢化硫化的情况下，纳米线的支撑物为硫转移的扩散途径更容易，以维持活性金属位点以进行脱硫活性。
