Abstract

Abstract

In order to improve the mechanical strength and reactivity of CaSO₄ oxygen carrier, the addition of glycerinum, silica sol and pseudo-boehmitewere to CaSO₄ oxygen carriers was applied by mechanical mixing, and the effect on the mechanical strength and the characteristics of reaction was experimentally investigated. The results show that the addition of glycerinum and silica sol significantly improves the mechanical strength of CaSO₄ oxygen carrier, while the pseudo-boehmite has little effect. TGA results indicate that the addition of glycerinum and silica sol can accelerate the reaction rate and decrease the reaction time. The XRD analysis demonstrates that the addition of binders doesn't affect the conversion from CaSO₄ to CaS and the conversion is nearly complete.
