Thermal transport phenomena in particulate-based carbonate systems undergoing chemical looping.
Lindsey Yue will present research on thermal transport in the heterogeneous solid–gas reacting system of calcium carbonate/calcium oxide for the applications of solar carbon dioxide capture and thermochemical energy storage.
Abstract: Thermochemical processes, and specifically those processes which involve heterogeneous solid–gas thermochemical looping of metal oxides, are important technologies with applicability to many research fields and industries. One such emerging field is concentrated solar thermochemistry. Metal-based thermochemical looping systems are being considered for use with concentrated solar thermal energy for the applications of carbon dioxide capture, thermochemical energy storage, and the production of synthetic transportation fuels. In this seminar, Lindsey will present research on thermal transport in calcium oxide-based particles undergoing chemical looping.
It will cover (1) thermodynamics and chemical kinetics of the calcium carbonate calcination and calcium oxide carbonation reactions, (2) the development of a numerical model of intra-particle heat and mass transfer applied to calcium carbonate/calcium oxide chemical looping, and (3) application specific investigations of the effect of process heat source and reacting material on thermochemical conversion.
