Kinetics of the high temperature desulfurization with mixed iron-calcium oxides in temperature programmed processes
程序升温过程铁钙氧化物高温脱硫动力学行为表征

Based on the thermogravimetric kinetics experiments, the equivalent grain model was applied to describe kinetics behavior of reduction and sulfidation of mixed iron-calcium oxides desulfurizer. In the temperature programmed reduction and sulfidation processes, activation energies and frequency factors changed as the solid conversion increased. Compensation effect of reduction was different from sulfidation. The former was positive compensation, while the latter was negative.
