摘　　要：石膏类工业固废主要包括磷石膏、脱硫石膏、氟石膏及钛石膏等,由于其杂质成分复杂等,极大地制约了其综合利用。近年来,随着我国"碳达峰"和"碳中和"目标的提出,国内对于二氧化碳捕集、利用与封存技术的研究日益增多。介绍磷石膏氨法直接固碳技术和石膏分解渣二步法固碳技术的研究进展,利用石膏捕集二氧化碳具有良好的技术及经济效益,将其作为一种高效、经济的钙基二氧化碳吸收剂具有广泛的应用前景。Industrial solid waste gypsum is mainly including phosphogypsum,desulfurization gypsum,fluorgypsum and titanium gypsum,etc.Due to the complex composition of impurities,the comprehensive utilization is greatly restricted.In recent years,with the proposal of the goals of"carbon peak"and"carbon neutralization"in China,the domestic research on carbon dioxide capture,utilization and storage is increasing day by day.The research progress of phosphogypsum ammonia direct carbon sequestration technology and gypsum decomposition slag two-step carbon sequestration technology are introduced.Using gypsum to capture carbon dioxide has good technical and economic benefits.As an efficient and economical calcium based carbon dioxide absorber,it has a wide application prospect.
