摘　　要：以太西煤和大同煤为原料,在配煤的基础上,通过添加镁盐M与硝酸盐N制得了微孔与中孔均较发达的活性炭。试验结果表明,大同烟煤配比较高时,有利于在低烧失率下制备高碘值、高亚甲蓝值的活性炭;添加剂M和N促进了3～4nm的中孔发育。Activated carbons were prepared from blended - coals made from Taixi coal and Datong coal in the presence of additives such as magnesium salts. The results show that at lower burn - off, the high content of Datong bituminous coal is favorable for preparing activated carbons with high iodine value and methylene blue value. It is also found that the additives can help to improve the development of porosity of activated carbons, especially good for the mesopores of 3～4 nm.
