摘要

Abstract

A two-dimensional non-isothermal mathematical model has been developed for the ethane dehydrogenation reaction in a fixed-bed catalytic membrane reactor. Since ethane dehydrogenation is an equilibrium reaction

removal of produced hydrogen by the membrane shifts the thermodynamic equilibriumto ethylene production. For further displacement of the dehydrogenation reaction

oxidative dehydrogenation method has been used. Since ethane dehydrogenation is an endothermic reaction

the energy produced by the oxidative dehydrogenation method is consumed by the dehydrogenation reaction. The results show that the oxidative dehydrogenation method generated a substantial improvement in the reactor performance in terms of high conversions and significant energy saving. It was also established that the sweep gas velocity in the shell side of the reactor is one of the most important factors in the effectiveness of the reactor.
