NaA type zeolite material as well as preparation method and application thereof
The invention relates to a preparation method of a NaA type zeolite material, which comprises the following steps of: drying titanium-containing blast furnace slag, mechanically ball-milling, and sieving to obtain powder of the titanium-containing blast furnace slag; mixing the powder and a hydrochloric acid solution in a beaker, stirring at room temperature, and then washing, filtering and drying the mixed solution to obtain acid treatment slag; uniformly mixing the acid treatment slag with NaOH powder in proportion, pouring into a crucible for roasting, cooling to room temperature, and grinding into powder to obtain a roasted material; putting the roasted material, an aluminum source and deionized water into a beaker, fully mixing, stirring at room temperature, transferring into a hydrothermal reaction kettle, crystallizing in a drying oven, cooling to room temperature after the reaction is finished, and filtering, washing and drying a reactant to obtain the NaA type zeolite material. In addition, the invention also relates to the zeolite material prepared by the method and application thereof. According to the invention, the NaA type porous zeolite with regular morphology and structure and excellent adsorption performance can be prepared, and the zeolite material can well capture CO2 gas.
本发明涉及一种NaA型沸石材料的制备方法，步骤为：将含钛高炉渣干燥并进行机械球磨后过筛，得到其粉末；将粉末与盐酸溶液置于烧杯中混合并在室温下搅拌，然后将混合液洗涤、过滤，并干燥得到酸处理渣；将酸处理渣与NaOH粉末按比例均匀混合，倒入坩埚中焙烧，冷却至室温，磨成粉，得到焙烧物料；将焙烧物料、铝源和去离子水置于烧杯中充分混合并在室温下搅拌，转移到水热反应釜在烘箱中进行晶化，待反应结束后冷却至室温，并将反应物经过滤、洗涤后干燥，得到NaA型沸石材料。此外，本发明还涉及上述方法制备得到的沸石材料及其应用。本发明可制备出形貌结构规整，吸附性能优异的NaA型多孔沸石，该沸石材料可以良好捕集CO2气体。
