生物基正丁醇具有替代化石基产品的巨大潜力，这一方面是由于原油的下降，另一方面是因为丁醇具有作为燃料的高潜力。为了使其生产达到工业规模，需要开发设计工艺的工具。在我们的工作中，我们专注于使用木材作为原料的第二代生物炼制。生物炼制由预处理、水解、发酵、丁醇回收和纯化组成。所提出的方法是一个多尺度的决策支持工具，选择的最佳工艺设计的生物炼制生产生物丁醇。最佳的生物精炼厂是从上层建筑中选出的，在工艺建模和模拟、经济和环境评估以及能源整合之后，重新描述了所有可行的方案。因此，最佳工艺是有利可图的，高效的和可持续的。此外，为了确定生物丁醇回收对发酵性能的影响，过程建模包括生物丁醇回收的反作用。在这项研究中，三个生物丁醇回收和四个纯化方案相结合，然后比较，以选择最佳的生物精炼生物丁醇生产。(C)2016爱思唯尔B.V.保留所有权利。
The bio-based n-butanol has major potential to replace fossil-based products due to, on the first hand, the decline of crude oil and, on the other hand, since the butanol has high potential as fuel. To set its production in industrial scale the development of tools designing the process is needed. In our work, we focus on second generation biorefinery using wood as feedstock. The biorefinery was composed by the pretreatment, the hydrolysis, the fermentation, the butanol recovery and the purification. The proposed methodology is a multiscale decision support tool for the selection of the optimal process design of the biorefinery producing biobutanol. The optimal biorefinery is selected from the superstructure recapping all feasible scenarios after process modelling and simulation, economic and environmental evaluations and energy integration. Thus, the optimal process is profitable, efficient and sustainable. Moreover, to identify the influence of the biobutanol recovery on the fermentation's performances, the process modelling includes the retroaction of biobutanol recovery. In this study, three biobutanol recovery and four purification scenarios are combined and then processes are compared to select the optimal biorefinery for the bio based butanol production.
