摘　　要：本文通过选取5种不同的煤样,添加不同比例的氧化镁,经磨粉、配煤、成型、炭化、活化等制备过程,以碘吸附值、磨损值、糖蜜值、氧化镁含量等为评价指标,制备载氧化镁活性炭。结果表明,当1号煤与2号煤及氧化镁配比为9∶1∶0.3、4号煤与5号煤及氧化镁配比为4∶6∶0.3时,均可制得满足预期指标碘吸附值≥950 mg/g、糖蜜值≥210、磨损值≥65%、MgO含量5%~8%的载氧化镁活性炭样品。其中,4号煤与5号煤及氧化镁配比为4∶6∶0.3、活化得率为25.62%时,可制备出碘值1057 mg/g、糖蜜值282、磨损值77%和MgO含量6.3%的样品。In this paper,by selecting five different coal samples,adding different proportions of magnesium oxide,after grinding,coal blending,molding,carbonization,activation and other preparation processes,using iodine number,attrition value,molasses number and magnesium oxide content as evaluation indexes,magnesium oxide loaded activated carbon was prepared.The results indicated that when the ratio of No.1 coal to No.2 coal and magnesium oxide is 9∶1∶0.3,and the ratio of No.4 coal to No.5 coal and magnesium oxide is 4∶6∶0.3,the magnesium oxide loaded activated carbon samples with iodine number≥950 mg/g,molasses number≥210,attrition value≥65%and MgO content 5%~8%can be prepared,meeting the expected target.Thereinto,when the ratio of No.4 coal to No.5 coal and magnesium oxide is 4∶6∶0.3 and the activation yield is 25.62%,the sample with iodine number 1057 mg/g,molasses number 282,attrition value 77%and MgO content 6.3%can be prepared.
