电石渣制备高附加值碳酸钙的研究进展
Research progress on preparation of calcium carbonate with carbide slag
摘要
Abstract
Preparation of calcium carbonate can achieve high value-added utilization of carbide slag, which is important to the sustainable development of chemical engineering of carbide. Preparation method,especially the process of leaching and carbonation were introduced. The progress in producing calcium carbonate with carbide slag as well as its surface modification and crystal controlling were reviewed. In leaching-carbonization method,ammonium chloride acting as leaching agent is recyclable,CO2 from waste gas can be used as carbonation agent,which is considered to have great potential and prospects. In preparation of calcium carbonate,surface modification of nano-calcium carbonate can be made as well. Calcium carbonate with different crystals and amorphous can be achieved through crystal control. Utilization of carbide slag in preparation of calcium carbonate shows the trend of elevation of added value. Study in the future should focus on the improving of circulative technic and deepen the study on ultra-fining,surface modification and crystal controlling of calcium carbonate in the utilization of carbide slag.关键词
