Abstract

|
The calcination characteristics of the waste Corbicula Japonica and Ostrea virginjca shell were examined for the future use as desulfurization sorbent. The weight variation was measured according to thermal-decomposition using TGA and observed variation of the phase. The qualitative and quantitative analysis of the sample were performed using XRD and the structural analysis, SEM. The results of TGA and XRD experiments showed that the almost all of the raw samples Corbicula Japonica and Ostrea virginjca were changed from calcite to lime by firing and calcination reaction. The result of SEM experiment showed that the plate type of the raw sample was changed to circle type, so the surface area ratio was increased. Above results suggested that waste Corbicula Japonica and Ostrea virginjca were usable in the viewpoint of the reuse of resource and the decrease of environmental pollution.
