Analysis of Experimental Conditions, Measurement Strategies, and Model Identification Approaches on Parameter Estimation in Plug Flow Reactors

Abstract

Continuous flow reactors such as plug flow reactors (PFRs) have been used in the identification of reaction systems (Moore, J. S.; Jensen, K. F. Angew. Chem. 2014, 126, 480−483). It is important to understand the impact of operating conditions, measurement strategies, and kinetic model identification methods on the identification of reaction systems in a PFR. Typically, for kinetic model identification using the simultaneous identification approach, concentrations are measured as a function of residence time under isothermal operating conditions in a PFR. On the other hand, concentrations and temperature are required to be measured as a function of residence time under non-isothermal conditions for kinetic model identification of multiple reaction systems in a PFR. In this work, we extend the incremental method for identification of kinetic and heat transport models using measurements from non-isothermal steady-state PFRs. This work investigates the role of experimental conditions, measurement strategies ...
