一种改性活性炭脱汞吸附剂及其制备方法
摘要：
本发明涉及一种改性活性炭脱汞吸附剂及其制备方法，该改性活性炭脱汞吸附剂由利用NH4Cl、NH4Br等卤化铵盐溶液浸渍改性原始活性炭，并烘干后制得。该改性活性炭脱汞吸附剂的制备方法包括：将原始活性炭破碎至50目以下；将破碎后的活性炭浸入NH4Cl、NH4Br溶液中，并连续搅拌12~15h；滤去废液，在45-50℃下，烘烤8~10h，烘干所得的固体物质，即制得该改性活性炭脱汞吸附剂。与原始活性炭相比，该改性活性炭脱汞吸附剂具有汞吸附量大、吸附速率高等优点。
摘要（英）：

The invention relates to a modified activated carbon demercuration adsorbent and a preparation method thereof. The modified activated carbon demercuration adsorbent is prepared by impregnating and modifying original activated carbon with a salt solution of NH4Cl, NH4Br or the like and drying. The preparation method comprises the following steps: crushing original activated carbon to less than 50 meshes; immersing the crushed activated carbon in a NH4Cl or NH4Br solution, and continuously stirring for 12-15 hours; filtering out waste liquor, and drying at 45-50 DEG C for 8-10 hours to obtain a solid matter which is the modified activated carbon demercuration adsorbent. Compared with the original activated carbon, the modified activated carbon demercuration adsorbent has the advantages of big mercury adsorption capacity, high adsorption rate and the like.
