摘要：以石油焦为原料 ,添加质量分数 3%～ 5 %的酸性活化剂 ,通过水蒸气法在实验室制得碘吸附值 5 2 1mg/g、CCl4吸附率 2 2 %的不定型颗粒炭 ,以及碘吸附值 80 0～ 90 0mg/g、亚甲基蓝吸附值 12 0mg/g、CCl4吸附率 38%～ 4 6 %、苯酚吸附值 180～ 2 6 0mg/g、灰分 3%～ 5 %、强度 91%～ 95 %的定型柱状颗粒炭。研究结果表明 ,酸性活化剂的添加有利于活性炭造孔 ,提高了活性炭的品质。在此基础上进行了定型颗粒炭的工厂放大实验 ,取得与实验室结果相当的产品 ,性能均达到或超过国家木质和煤质净水炭标准。
Activated carbon from petroleum coke was prepared by the method of water-steam activation with the addition of 3%-5%(mass part) acid activating agent.Broken granular activated carbon has the specifications of iodine value 521 mg/g,carbon tetrachloride(CCl_4) adsorption 22%,and shaped cylindrical activated carbon has the specifications of iodine value 800-900 mg/g,methylene blue adsorption 120 mg/g,CCl_4 adsorption 38%-46%,phenol (adsorption) 180-260 mg/g,ash 3%-5%,hardness 91%-95%.Results showed that acid activating agent is beneficial to create the micropore of activated carbon and improves the quality of activated carbon.Based on laboratory (results),enlarged experiment in factory was carried out and the obtained products were similar to the sample acquired in the laboratory.Their performances both reached or exceeded national standards of wood-based and coal-based (activated) carbon for refining water.
