Acid mist composite adsorbent as well as preparation method and application thereof

The invention discloses an acid mist composite adsorbent as well as a preparation method and application thereof, and relates to the technical field of adsorption materials. According to the preparation method, amination treatment is carried out through the MOFs material, aluminum oxide, activated carbon and kaolin are modified, and the two modified materials are utilized to prepare the composite adsorbent, so that the composite adsorbent has relatively high porosity and specific surface area. When the composite adsorbent is in an acid mist environment, the composite adsorbent disclosed by the invention can be in full contact with acid mist, so that the removal of the acid mist is facilitated. The specific surface area of the composite adsorbent is increased, and meanwhile the adsorption capacity and stability of the composite adsorbent are further improved. 本发明公开了一种酸雾复合吸附剂及其制备方法和应用，涉及吸附材料技术领域。本发明通过MOFs材料对胺基化处理以及对氧化铝、活性碳、高岭土进行改性，并利用上述两种改性材料制成一种复合吸附剂，使得其具有较高的孔隙度和比表面积。当复合吸附剂处于酸雾环境中时，本发明复合吸附剂可以和酸雾充分接触，从而有利于酸雾的脱除
