THERMODYNAMIC ANALYSIS OF CYCLOHEXANE DEHYDROGENATION IN MEMBRANE REACTOR

Abstract

Abstract: The cyclohexane dehydrogenation is a model reaction of membrane reactor. The thermodynamic analysis was used to calculate the change of Gibbs free energy, equilibrium constant at different temperatures, and the cyclohexane equilibrium conversion with different removal rates of hydrogen of the reaction system. And the influence of different removal rates of hydrogen on cyclohexane equilibrium conversion was investigated. Further the severity of the reaction and the increasing percentages of equilibrium conversion of cyclohexane with different removal rate of hydrogen were investigated and compared with that of the conventional fixed bed reactor. The potential use of membrane reactor in improving cyclohexane equilibrium conversion of the reversible dehydrogenation reaction was described. It is found that the cyclohexane equilibrium conversion achieved in membrane reactor is higher than that in conventional fixed bed reactor. The results show that membrane reactor can effectively improve the equilibrium conversion of cyclohexane, and reduce the severity of the reaction, indicating its good prospect for industrial applications.

Key words: thermodynamic analysis, cyclohexane dehydrogenation, membrane reactor, conversion
