78. Studies on Oxidation of Calcium Sulfide under an Advanced PFBC Cycle

抄録

Calcium sulfide oxidation reaction had been investigated at temperatures between 900 and 980℃ with 1-21%O_2 in N_2 by using TG apparatus. The kinetics analysis and reaction scheme deduction were performed, and effects of particle size, oxygen concentration and temperature were also discussed. A mathematical model (grain model) had been applied to describe the reaction process.
