石灰石和贝壳的煅烧及CO2吸收循环特性
Kinetic and Cyclic Absorbing CO2 Characteristics of Limestone and Shell
摘要
Abstract
In the paper, natural limestone and shell were chosen as calcium-based materials for calcination/carbonation cyclic reactions due to their low cost and rich resources. The calcinations kinetic characteristics and CO/ adsorption characteristics of both materials were studied using thermo- gravimetric analysis （TGA）. Simultaneously, product was used to investigate the particle size distribution and scanning electron microscopy （SEM） of products pre and post the cycle. The results show that the adsorption activities of both materials decreases as the cycle number increases. From the particle size distribution and SEM of samples after multiple cycles, it is obtained that the number of micro-pore decreases and the sintering degree is serious for limestone, while the particle sizes of shell distributed between medium and large. Shell also had a relatively low rate of calcium utilization and its appearance hadn＇t changed significantly. For the difference in component and structure, natural limestone has a better cyclic adsorption activity than shell. However, shell exhibites the better cyclic stability.关键词
