Abstract

Compared with inorganic chemical heat pumps (CHPs), organic liquid-gas CHPs are more amenable to be run as a continuous process because the reactants and products can be fed or removed continuously. Therefore, increasing attention has been paid to investigations of CHPs using the organic liquid-gas reaction system. Relevant research topics involved reaction catalyst, chemical reaction kinetics, reactive distillation, energy efficiency evaluation, economic analysis, etc. Nevertheless, the research on an organic liquid-gas CHP system is still in the elementary stage. A detailed review on the current research status of catalyst-assisted CHPs employing an organic liquid-gas reaction system has been performed. Existing problems are identified and future research directions are proposed. A detailed overview on the current research status of catalyst-assisted chemical heat pumps (CHPs) using an organic liquid-gas reaction system is presented and the existing problems are addressed. Aiming at resolving these problems, the future research directions for the system and component levels are pointed out. The organic liquid-gas CHP system is believed to be the main trend for future development.
