The reaction of thermal decomposition of CaCO3 to produce CaO and CO2 is an important reaction during the Ca-looping process. The Ca-looping process has great potential in environmental and energy application

such as flue gas decarbonization

H2 production from a reactive sorption enhanced reforming process and sun heat energy storage. One essential criterion to evaluate the properties of CaCO3 thermal decomposition is the decomposition temperature and the decomposition rate. From the decomposition mechanism

thermodynamics and kinetics

this paper analyses the effect of the selected factors on the decomposition temperature and rate

including particle size

microstructure and composition

heating rate

decomposition atmosphere and pressure. The summarization of the research above is to provide reference methods for accelerating the thermal decomposition and reducing the energy consumption in decomposition during the industrial applications.
