For this heat pump kinetic study, the dehydration rate of tert-butanol (an endothermic reaction) was measured under conditions suitable for operating a chemical heat pump. The proposed Langmuir-Hinshelwood rate equation agreed well with the experimental rate data. The heat pump kinetic study was examined in a batchwise operation by using both the endothermic reaction rate equation and a previously proposed rate equation for the exothermic reaction. Although the endothermic reaction rate was suitable for a heat pump, an improvement of the endothermic reaction rate was desired since it was found to be too slow. The endothermic reaction was about 5 to 20 times slower than the exothermic reaction. The absorbed and released heat rates per batch cycle were almost the same as for conventional heat pumps.
