Abstract

A packed-bed reactor heated with an IR furnace is designed and fabricated for high-temperature thermochemical energy storage (TCES) studies using 0.5–1.0 mm particles composed of iron–manganese oxide with a molar ratio of Fe/Mn 2:1 (Fe67) as the storage material. An axisymmetric, two-dimensional, transient model accounting for heat transfer (conduction, convection, and radiation), mass transfer, and thermochemical reaction kinetics is developed to describe the reduction reaction of Fe67 in the packed-bed reactor. The model and experiments are in good agreement, indicating that the model is useful for providing a fundamental understanding of the process.
