This Small Business Innovation Research Phase I project will develop a one-step membrane reactor-based process to clean-up, concentrate, and condition bio-based syngas to make it suitable for downstream processing into fuel or chemicals. The biomass-based energy production pathway has been favored recently due to no/minimal net CO2 emission. The recent skyrocketing prices of imported crude have made domestically available biomass a very attractive alternative fuel and chemical source. Thermochemical conversion of biomass into fuels and chemicals has been considered one of the better developed bio-based energy production processes. However, today for thermochemical conversion of biomass to play a significant role in reducing our country's dependence on imported fossil fuels, the syngas generated during biomass gasification must be (i) meticulously cleaned to remove trace contaminants (e.g., tar, H2S, NH3, HCl, etc.), (ii) concentrated via removal of a broad range of diluents (e.g., N2, O2, CH4, etc.), and (iii) conditioned to the proper ratio to meet the feedstock requirements of such diverse products as hydrogen for fuel cells or syngas for methanol and higher alcohol synthesis and for hydrocarbon production via Fischer-Tropsch. During Phase I of this project, the gas clean-up/concentration/conditioning process based upon the proposed one-step concept will be demonstrated in a bench top unit with synthetic feeds. The experimental and simulation results thus generated will be used to validate the proposed technical concept and provide economic basis for the next phase technical and commercial development with an end user participant.The development of this process will play a pivotal role in linking the existing upstream biomass gasification technology with the downstream hydrogen or syngas use technology. The production cost using existing technology was about 2 to 4 times of the cost of fossil diesel in 2004. By implementing this technology, the projected bio-based fuel cost will be in line with current fossil fuel prices according to preliminary cost analyses. The development and commercialization of this process will play a pivotal role in linking the existing upstream biomass gasification technology with the downstream syngas to fuel/chemical conversion technologies and will boost the domestic energy supply with minimal net greenhouse gas emissions.

这个小型企业创新研究阶段I项目将开发一个基于单步膜反应堆的工艺，以清理，浓缩液和基于生物生物的合成器，以使其适合下游加工到燃料或化学物质中。由于没有/最小的净二氧化碳排放，因此基于生物质的能源生产途径最近受到青睐。最近，进口原油的价格飞涨使国内可用的生物量成为非常有吸引力的替代燃料和化学源。生物量转化为燃料和化学物质的热化学转化已被认为是基于生物的能源生产过程之一。 However, today for thermochemical conversion of biomass to play a significant role in reducing our country's dependence on imported fossil fuels, the syngas generated during biomass gasification must be (i) meticulously cleaned to remove trace contaminants (e.g., tar, H2S, NH3, HCl, etc.), (ii) concentrated via removal of a broad range of diluents (e.g., N2, O2, CH4等）和（iii）以适当的比率为条件，以满足诸如用于燃料电池的氢或甲醇和较高酒精合成的氢的原料要求，以及通过Fischer-Tropsch的碳氢化合物的生产。在该项目的第一阶段中，将在带有合成饲料的基准顶部单元中证明基于提出的一步概念的气体清理/浓度/调理过程。这样生成的实验和仿真结果将用于验证拟议的技术概念，并为下一个阶段的技术和商业开发与最终用户参与者提供经济基础。该过程的开发将在将现有上游生物质量气化技术与下游氢或Syngas使用技术联系起来，在将现有上游上游生物质量加油技术联系起来。使用现有技术的生产成本约为2004年化石柴油成本的2到4倍。通过实施这项技术，预计的基于生物的燃料成本将与当前的化石燃料价格一致，根据初步成本分析。该过程的开发和商业化将在将现有的上游生物量气化技术与下游合伙们与燃料/化学转化技术联系起来，并将以最小的净温室气体排放量提高国内能源供应。
