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.
