Summary

Chemical heat pumps represent a new technology with great potential to reduce energy consumption in very different sectors. They can provide the ability to capture the rejected low-grade heat and to reuse it at higher temperature levels in various industrial processes. Heat can be removed from a heat source at low temperature by an endothermic reaction and can be boosted to a heat sink at high temperature by an exothermic reaction. Since chemical heat pumps can operate without compression, with less electrical power and at higher temperature levels compared with conventional heat pumps, they can afford high performance advantages. As an additional advantage, energy storage can also be accomplished so that intermittent energy sources can be utilized in a chemical heat pump system. The objective of this work was to study methanol-formaldehyde-hydrogen, ethanol-acetaldehyde-hydrogen, i-propanol-acetone-hydrogen and n-butanol-butyraldehyde-hydrogen chemical heat pumps.
