For the automation of the evaluation of kinetic data, we have built up a modular laboratory unit with three difl'erent continuously working gradientless reactors (CSTR, double-mixed-contactor, betty-reactor). The experimental plan and the laboratory unit are controlled by a process-control-system In the CSTR we have determined kinetic data for a three-phase enzymatic reaction The NO-absorption was part of our resarch in the double-mixed-contactor. The results of our investigation and the problem of automation are the content of this paper.
AUTOMATION OF DETERMINING KINETIC DATA
A major problem in research of reaction kinetics is the evaluation of experimental data, which lead to useful micro-, macro-or formal kinetic models. In the past, different types of reactors have been developed to increase accuracy of experimental data. The idea of working with gradientless reactors, which simplify the calculation of reaction kinetics, has been established for almost all reaction systems. Three different types of reactors, which are the CSTR for gas-liquid-solid reactions, the berty-Reactor for heterogenous gas-solid reactions and the double-mixed-contactor for gas-liquid reactions enable to determine kinetic data in industrially relevant systems.
