Workshop: Developing New Paradigms for Biofuel Separations to Enable an Alternative Fuels Future

1104933 Shantz美国转向替代燃料有许多重要的驱动因素。这些措施包括减少我们对外国进口石油的依赖，减少化石燃料利用造成的气候变化的有害影响，创造一个新的工业部门（绿色能源），为未来的劳动力提供高质量的就业机会。有许多路线正在探索和吹捧作为化石燃料的替代品，包括风能，太阳能，氢能和核能。一个更有希望的可能性是从非食用作物中开发生物燃料。生物燃料的关键优势之一似乎是生物质的转化可以使用已知的技术，如热解，水解，发酵等，然而，该领域的关键挑战之一是，这些过程总体上是非选择性的。因此，虽然用于将生生物质加工成基础产品原料的反应器技术是可用的，但是对于开发用于升级基础产品原料的方法将存在相当大的需求。从通过热解/水解产生的流中选择性地去除所需组分（例如糖、糠醛）的能力将代表将可再生原料掺合到现有燃料生产方案中或导致用于燃料生产的全新路线的简单路线。前者是一个合乎逻辑的中间目标，将有利于燃料行业实现政府规定的将可再生化合物纳入燃料池的目标。后者代表了使该国远离化石燃料的最终目标。基于这些观点，人们认为，将需要新的分离方案，以充分发挥生物燃料的潜力。本次研讨会将有三个主题：1。讨论了原料加工的最新技术，重点是所得生物混合物的性质，特别是与潜在分离相关的性质。2.讨论应用于生物燃料加工的液体分离的现状。3.总结会议概述了该领域面临的关键和独特的挑战，将为该领域的未来工作和目标制定路线图。

1104933ShantzThere are many significant drivers for the United States to shift to alternative fuels. These range from reducing our dependency on foreign imports of oils, to the deleterious effects of climate change that are driven by fossil fuels utilization, to creating a new industrial sector (green energy) that will provide high quality jobs for the future work force. There are many routes being explored and touted as alternatives to fossil fuel, including wind, solar, hydrogen, and nuclear energy. One of the more promising possibilities is the development of biofuels from non-edible crops. It would appear that one of the key advantages of biofuels is that conversion of biomass is possible using known technologies such as pyrolysis, hydrolysis, fermentation etc. However, one of the key challenges in this area is that these processes on whole are nonselective. Thus, while the reactor technology for processing raw biomass into a base product feedstock is available, there will be considerable needs for the development of methods for upgrading the base product feedstock. The ability to selectively remove desirable components (e.g. sugars, furfurals) from streams produced by pyrolysis / hydrolysis would represent a simple route to either blending renewable feedstocks into existing fuel production schemes or lead to whole new routes for fuel production. The former represents a logical intermediate target that would be beneficial to the fuels industry meeting government-mandated targets for integration of renewable compounds into the fuel pool. The latter represents the ultimate goal of moving the country away from fossil fuels. Based on these points, it is believed that new separation schemes will be needed for biofuel utilization to reach its full potential. This workshop will have three major themes: 1. A discussion of the state of the art in feedstock processing, with an emphasis on the nature of the resulting bio-mixtures, particularly focused on properties of relevance for potential separations. 2. A discussion of the current state of liquid separations applied to biofuels processing. 3. A summary session outlining the key and unique challenges facing this area that will lay out a roadmap for future work and goals in the field.
