Thermochemical Dissociation of Water and Carbon Dioxide via ZnSI Cycle for Hydrogen and Carbon Monoxide Production

Thermochemical water and carbon dioxide splitting via zinc sulfur iodine (ZnSI) cycle coupling with renewable energy sources as the source of high temperature process heat, is a promising solution to produce hydrogen and carbon monoxide, which can alleviate CO2 emissions from the combustion of various fossil fuels. The synthetic liquid fuels are achieved with the combination of CO and H2. The process design of this novel approach has been carried out on the basis of six associated chemical reactions. The theoretical maximum energy conversion efficiency of the cycle has been evaluated according to basic thermodynamic laws.
