Even though hydrogen possesses the highest energy content per unit weight compared to any of the knownfuels, and burns cleanly, it does not exist in the free form. An economically viable way to obtain hydrogen fromrenewable sources will provide a good alternative to the present world-wide reliance on fossil fuels. There is ahuge opportunity to develop the capacity to use components derived from non-purified, non-food biomassderived feed materials for hydrogen production because this would ease the pressure in using food basedbiomass, eliminate the huge amount of energy required for purification, and provide added benefit forconverting wastes to value added products. These components could be derived from non-intensive processesfor conversion of cellulosic materials to oxygenated hydrocarbons (i.e. not specific to ethanol alone) easily at alow cost. Also, the oxygenated hydrocarbons could be obtained as wastes from biodiesel production. Thesemultiple sources of oxygenated hydrocarbons ensures that the hydrogen production process can managefeedstock supply and volatility. Furthermore, in order to derive an additional advantage from the use ofbiomass materials to achieve huge environmental benefits, CO2 capture must be incorporated in the process.This will ensure that we not merely achieve a net zero emissions, but actually use the process to extract CO2that already exists in the atmosphere. Our objectives are to: (i) develop a high performance catalyst for thereforming of any non-food or waste biomass derived crude mixtures of liquid oxygenated hydrocarbonsincluding higher alcohols, organic acids, glycerol, etc., (ii) develop the process conditions as well as integrationand optimization strategies for the process, and (iii) develop and incorporate a CO2 capture strategy for theproduction of the cleanest fuel, hydrogen.

尽管与任何已知的燃料相比，氢具有最高的单位重量能量含量，并且燃烧清洁，但它并不以自由形式存在。从可再生能源中获得氢气的经济可行的方法将为目前世界范围内对化石燃料的依赖提供一个很好的替代方案。有一个巨大的机会来发展使用来自非纯化的、非食品生物质来源的原料的组件来生产氢的能力，因为这将缓解使用基于食品的生物质的压力，消除纯化所需的大量能量，并为将废物转化为增值产品提供额外的好处。这些成分可以从非密集的过程中获得，用于以低成本将纤维素材料容易地转化为含氧烃（即不特定于单独的乙醇）。此外，含氧烃可以作为生物柴油生产的废物获得。氧化烃的多种来源确保了氢气生产过程可以管理原料供应和挥发性。此外，为了从生物质材料的使用中获得额外的优势，以实现巨大的环境效益，二氧化碳捕获必须纳入这一过程。这将确保我们不仅实现净零排放，而且实际上使用这一过程来提取已经存在于大气中的二氧化碳。我们的目标是：（i）开发用于重整任何非食品或废弃生物质衍生的液体含氧烃的粗混合物的高性能催化剂，所述含氧烃包括高级醇、有机酸、甘油等，(ii)开发工艺条件以及工艺的集成和优化策略，以及（iii）开发并纳入CO2捕获策略，以生产最清洁的燃料氢气。
