A Novel Application of FT-IR Spectroscopy for the Kinetics of High-Temperature Reaction of SO 2 with CaO

Abstract

FT-IR spectroscopy has been used to investigate the kinetics of SO₂/CaO reaction at high temperatures, 700 to 1000°C. The estimated kinetic parameters, namely the activation energy (34.7 kcal/mole) and the order with respect to SO₂ partial pressure (∼0.60 ± 0.02) are in excellent agreement with the earlier reports where thermogravimetric and chemical analysis methods were used, thus supporting FT-IR spectroscopy as a viable tool for the kinetics of gas/solid reaction at high temperatures.
