Nanometer layered porous calcium hydroxide as well as preparation method and application thereof
The invention provides nano layered porous calcium hydroxide as well as a preparation method and application thereof. The preparation method of the nanometer layered porous calcium hydroxide is based on an alcoholic solution method, the technological method is simple, efficient, economical and feasible, the requirements for used equipment and instruments are simple, a high-price polymerization inhibitor and alkali liquor do not need to be added, and the digestion reaction can be rapidly completed under the room temperature condition. The prepared nano calcium hydroxide is of a layered porous structure, the particle size reaches the nanoscale, the size is uniform, the dispersity is good, and the specific surface area can reach 40 m < 2 >/g or above. The prepared calcium hydroxide material can efficiently remove low-concentration SO2, is generally suitable for dry desulfurization processes of small and medium-sized enterprises, and can effectively reduce investment and operation cost compared with other flue gas purification modes.
本发明提供了一种纳米层状多孔氢氧化钙及其制备方法和应用。本发明的纳米层状多孔氢氧化钙的制备方法，基于醇溶液法，工艺方法简单高效、经济可行，所使用的设备及仪器要求简单，无需添加高价阻聚剂和碱液，在室温条件下及可快速完成消化反应。本发明制备的纳米氢氧化钙呈层状多孔结构，颗粒粒径达到纳米尺度，大小均匀，分散性良好，比表面积可达40m2/g以上。所制备氢氧化钙材料可高效去除低浓度SO2，普遍适用于中小型企业的干法脱硫工艺，与其它烟气净化方式相比，可有效降低投资和运营成本。
