Based on temperature swing concept arising from forced periodic variations in feed conditions, a theoretical study of a novel catalytic reactor system is carried out, in which adsorption and reaction occur simultaneously. In order to evaluate the performance of a temperature swing adsorptive reaction(TSAR) process for various operating conditions, the rigorous dynamic model of the reactor is developed and dynamic simulation is performed. In the application of the concept suggested in this paper, the dehydrogenation process of methyl-cyclohexane(MCH) to produce toluene is employed and the conversion and energy consumption is calculated. The results are compared with the case of isothermal equilibrium reaction. For the whole range of investigation, it is examined TSAR process is superior to an isothermal equilibrium reactor in the sense of a convection and energy saving. In the consideration of the results of this study, TSAR process can provide a means for the effective utilization of a waste heat source for reaction heat and for feed gas preheat; periodic catalyst regeneration; the generation of optimal temperature for the improvement of a conversion; and reaction enhancement for theoretically limited reactions.
