The world is currently witnessing a significant shift in the production of chemicals using new "biorefinery" technologies. Indeed, biorefinery will contribute to the integration of food into industrial processing. For instance, cereals can be used to produce food, whereas crop residues, fibrous byproducts, and other cellulosic materials can serve for industrial power, biochemicals, and fuels. It is only through these integrated processing plants that the biobased industrial sector will expand without increasing the cost of food and diverting agricultural production from its primary goal. Such products are bioethanol and biobutanol, which are renewable and sustainable energy sources, may significantly reduce pollution. It is proposed to investigate various ways of significantly reducing the production cost of biofuel produced mainly from cellulosic materials. A major portion of the cost to produce bioethanol is due to the high energy requirement for separating ethanol from the fermentation broth. This problem is compounded by the fact that the final ethanol concentration is commonly very low. For biobutanol, the concentration is even lower. In this research program, it is proposed to investigate various fermentation and hybrid separation (adsorption, membrane, dephlegmator) strategies to address the difficulties of low bioalcohol concentrations. State-of-the-art process synthesis, integration, and optimization will be used to devise the best possible ethanol production flow sheets. Numerous scenarios will be assessed completely from both a technological and economic point of view. A good number of graduate and undergraduate students will take part in this program and will be exposed to the various facets of bioethanol and biobutanol production plants.

目前，世界正在见证利用新的“生物精炼”技术生产化学品的重大转变。事实上，生物精炼将有助于食品融入工业加工。例如，谷物可用于生产食物，而农作物残留物、纤维副产品和其他纤维素材料可用于工业动力、生物化学品和燃料。只有通过这些综合加工厂，生物基工业部门才能在不增加食品成本和使农业生产偏离其主要目标的情况下扩大规模。此类产品是生物乙醇和生物丁醇，它们是可再生和可持续能源，可以显着减少污染。建议研究显着降低主要由纤维素材料生产的生物燃料的生产成本的各种方法。 生产生物乙醇的成本的主要部分是由于从发酵液中分离乙醇需要高能量。由于最终乙醇浓度通常非常低，这一问题变得更加复杂。对于生物丁醇，浓度甚至更低。在该研究计划中，建议研究各种发酵和混合分离（吸附、膜、分凝器）策略，以解决低生物酒精浓度的困难。最先进的工艺合成、集成和优化将用于设计最佳的乙醇生产流程图。许多情景将从技术和经济角度进行全面评估。 许多研究生和本科生将参加该计划，并将接触到生物乙醇和生物丁醇生产工厂的各个方面。
