Electrochemical fluidized bed reactors for electro-enzymatic syntheses including gaseous phases: Part II. Modelling, Scale-up and in-line process monitoring

拟议项目的总体目标是进一步开发三相流化床电化学反应器，作为非常有前途的电-酶-以及从长远来看-增值产品的电-微生物合成系统。第二个供资期的一揽子工作重点特别是：（i）开发一种设计，该设计允许有效地将反应器按比例放大到工业相关的尺寸，并允许舒适地处理和交换酶载体以实现长期操作，（ii）通过将反应器耦合到质谱仪（MS）来实现合成反应物的灵活且灵敏的实时分析。MS对各种目标分子的快速适应将允许研究不同的电-酶反应系统，而分析的实时特性将允许对电和化学性能指标之间的相关性的动力学解析的见解，（iii）扩展和概括建模活动，以便获得关于过程限制的全面知识，特别是在以提高的电流密度运行的规模化反应器中。学习到的相关性将转化为通用设计规则，灵活的模型应用程序将在COMSOL服务器上实现，以供通用，而无需COMSOL许可证或详细的建模知识。

The overall objective of the proposed project is the further development of three-phase fluidized bed electrochemical reactors as highly promising systems for electro-enzymatic – and in perspective – also electro-microbial synthesis of value-added products. The foci of the work packages in the second funding period are in particular: (i) the development of a design which allows to effectively scale the reactor into industrially relevant dimensions and to allow the comfortable handling and exchange of enzyme carriers to enable long-term operation, (ii) to implement a flexible and sensitive real-time analysis of the reactants of the synthesis by coupling the reactor to a mass spectrometer (MS). The fast adaption of MS to various target molecules will allow the investigation of different electro-enzymatic reaction systems, while the real-time character of the analysis will allow kinetically resolved insights into correlations between electrical and chemical performance indicators, (iii) to extend and generalize the modelling activities in order to gain a comprehensive knowledge about process limitations, especially in scaled reactors running at elevated current densities. The correlations learned, will be transferred into general design rules and flexible model apps will be implemented on a COMSOL server for general use without the need for a COMSOL license or detailed modelling knowledge.
