TL;DR: In this paper, the authors present a set of reaction model equations that describe the behavior of a reactor with sufficient accuracy, which are then used in a reactor model, i.e., a subset of equations that can be used to describe the behaviour of a reaction model with enough accuracy.

Abstract: The rational design, simulation and optimization of an industrial reactor has to be based on accurate, reliable data for mass, energy and momentum transport as well as chemical kinetics. For this purpose specially designed laboratory or pilot experiments are needed, as only in very rare cases is a theoretical evaluation possible. The aim of any kinetic data analysis in reaction engineering is to find adequate reaction model equations and to arrive at reliable parameter estimates dependent on the operating variables of the reactor, like pressure, temperature, flow conditions etc. These parameters then will be used in a reactor model, i.e., a set of equations that describe the behavior of a reactor with sufficient accuracy.
