This Small Business Technology Transfer (STTR) Phase I project will develop a commercially viable ethanol process via a multi-functional membrane-based reactor using the best available catalyst. The proposed reactor incorporates the advantages of existing reactors which result from the in-situ product removal, without being hampered by some of the associated disadvantages, such as inefficient removal of the exothermic reaction heat. A nearly 100% carbon monoxide (CO) conversion with a high selectivity to ethanol is theoretically and practically feasible in this single stage reactor. Process intensification, as a result of the application of the proposed multi-functional reactor, will result in high efficiencies, low capital costs, and a small overall footprint, all required for the process to be a commercially viable. The broader impact/commercial potential of coal-derived ethanol is an affordable, efficient hydrogen carrier that can be distributed and stored using the nation?s existing fuel infrastructure. In addition, as is also the case with bio-ethanol (albeit at a smaller scale), coal-derived ethanol can provide an interim solution as a liquid automobile fuel/additive before the hydrogen-based economy is fully implemented. Ethanol derived from the abundant domestic supply of coal can reduce dependence on imported energy, and more importantly, offers an attractive alternative to bio-ethanol. An efficient coal-to-ethanol production process offers an economically driven ethanol supply (as opposed to subsidized bio-ethanol) to the growing market demand in the near-term, while providing a high energy density feedstock from domestically available coal for distributed hydrogen production in the long-term when the hydrogen-based economy will be fully implemented.

这个小型企业技术转移（STTR）I期项目将使用最佳可用催化剂通过基于多功能的膜反应堆开发商业上可行的乙醇工艺。所提出的反应器包含了由原位产品去除产生的现有反应器的优势，而不会受到某些相关的缺点的阻碍，例如对放热反应热的效率低下。在这个单阶段反应堆中，对乙醇具有高选择性的近100％碳（CO）转化是对乙醇的高选择性。由于提出的多功能反应器的应用，过程强化将导致高效率，低资本成本和较小的整体足迹，这是该过程成为商业上可行的所有这些所必需的。煤炭衍生的乙醇的更广泛的影响/商业潜力是一种负担得起的，有效的氢载体，可以使用该国现有的燃料基础设施进行分发和存储。此外，与生物乙醇（尽管规模较小）也是如此，煤源性乙醇可以在完全实施基于氢的经济之前作为液体汽车燃料/添加剂提供临时溶液。源自大量的煤炭供应的乙醇可以减少对进口能源的依赖，更重要的是，它为生物乙醇提供了一种有吸引力的替代品。有效的煤炭到乙醇生产过程提供了经济驱动的乙醇供应（与补贴的生物乙醇相反）在近期的市场需求中，同时提供了从国内可用的煤炭提供的高能量密度的原料，用于长期在氢经济中实施的长期分布式氢生产。
