Summary

A chemical heat pump, based on the reversible reaction couple of the i-propanol-acetone system, was investigated experimentally. The endothermic dehydrogenation of i-propanol occurred at 80 deg C with a Raney nickel catalyst suspended in the liquid phase. The exothermic hydrogenation reaction of the acetone was performed at 200 deg C and 1 atm, in the presence of the Raney nickel catalyst. The positive value of the change of Gibbs free energy can make the dehydrogenation reaction of i-propanol rather difficult. This problem can, though, be overcome by the continuous removal of gaseous acetone and hydrogen products from the reaction medium.
