Method for preparing gelling material from multi-element solid waste mineralized carbon dioxide and residues of multi-element solid waste mineralized carbon dioxide
The invention discloses a method for preparing a cementing material from multi-element solid waste mineralized carbon dioxide and residues thereof, and belongs to the technical field of industrial solid waste and fixed carbon utilization. The method comprises the following steps: mechanically and finely grinding and activating steel slag and magnesium slag in advance, and pre-sorting coal gasification fine slag to obtain decarburized coal gasification fine slag; then Ca < 2 + > in the three raw materials is leached out by utilizing an alcohol amine solution and is used for mineralizing CO2 to prepare high-purity nano calcium carbonate; and finally, preparing the binding material from the residual residues. According to the method, the comprehensive utilization value of the multi-element solid waste is effectively improved, and meanwhile, the high-purity nano calcium carbonate product is produced. The method has potential economic, social and environmental benefits.
本发明公开了一种多元固废矿化二氧化碳及其残渣制备胶凝材料的方法，属于工业固废、固碳利用技术领域。该方法将钢渣、镁渣预先机械细磨活化，将煤气化细渣预先分选得到脱炭煤气化细渣；然后利用醇胺溶液将三种原料中的Ca2+浸出，用于矿化CO2制备高纯度纳米碳酸钙；最后将剩余残渣制备胶凝材料。本发明有效提高多元固废的综合利用价值，同时生产了高纯度纳米碳酸钙产品。本发明具有潜在的经济、社会和环境效益。
