In this work, we show that the continuous flow stirred tank reactor (CFSTR) equivalence principle, developed by Feinberg and Ellison, can be used to obtain practical upper bounds on reaction selectivity for any chemistry of interest. The CFSTR equivalence principle allows one to explore the attainable reaction region by decomposing any arbitrary, steady-state reactor-mixer-separator system with total reaction volume V > 0 into a new system comprising inline image CFSTRs (where inline image is the number of linearly independent chemical reactions) with the same total reaction volume and a perfect separator system. This work further refines the allowable selectivities by incorporating capacity constraints into the CFSTR equivalence principle to prevent arbitrarily large recycle streams between the CFSTRs and the separators and infinitesimally small CFSTR conversions. These constraints provide practical upper bounds on reaction selectivities of chemistries completely independent of reactor design. We present the methodology and the results for a selection of realistic chemistries. © 2017 American Institute of Chemical Engineers AIChE J, 2017

通过Feinberg的CFSTR等价原理确定反应选择性的目标范围

在这项工作中,我们证明了由Feinberg和Ellison开发的连续流搅拌釜反应器(CFSTR)等效原理可用于获得任何目标化学反应的反应选择性的实用上限。CFSTR等价原理允许人们通过将总反应体积V> 0的任意稳态稳态反应器-混合器-分离器系统分解为一个包含内嵌图片CFSTR的新系统来探索可达到的反应区域 (其中 内嵌图片是线性独立的化学反应的数量),总反应体积相同,分离器系统完善。通过将容量约束纳入CFSTR等价原理中,这项工作进一步完善了可允许的选择性,以防止CFSTR和分离器之间任意大的循环料流以及无限小的CFSTR转化。这些限制为化学反应的选择性提供了实用的上限,而完全不依赖于反应器的设计。我们介绍了选择实际化学方法的方法和结果。©2017美国化学工程师学会AIChE J,2017
