INFLUENCE OF HYDROGEN-PERMEABLE MEMBRANES UPON THE EFFICIENCY OF THE HIGH-TEMPERATURE CHEMICAL HEAT-PUMPS BASED ON CYCLOHEXANE DEHYDROGENATION BENZENE HYDROGENATION REACTIONS

In this paper the flow diagram for a high-temperature chemical heat pu mp (HTCHP) based on the reversible cyclohexane dehydrogenation-benzene hydrogenation reactions is analyzed. The peculiarity of this diagram is a multipurpose use of hydrogen-permeable membranes. A thermodynamic analysis of the proposed flow diagram is undertaken in order to exami ne the influence of different factors on the coefficient of performanc e of the heat pump and on the pressure in the dehydrogenation reactor. It is shown that the new flow diagram with the hydrogen-permeable mem branes allows us to improve the performance of the HTCHPs and to exten d the field of their practical application.
