KINETIC MEASUREMENT ON THE ISOBUTENE WATER/TERT-BUTANOL CHEMICAL HEAT-PUMP - DEHYDRATION OF TERT-BUTANOL/

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 k inetic study was examined in a batchwise operation by using both the e ndothermic reaction rate equation and a previously proposed rate equat ion for the exothermic reaction. Although the endothermic reaction rat e was suitable for a heat pump, an improvement of the endothermic reac tion rate was desired since it was found to be too slow. The endotherm ic reaction was about 5 to 20 times slower than the exothermic reactio n. The absorbed and released heat rates per batch cycle were almost th e same as for conventional heat pumps.
