摘要: 以洗煤厂的废料为原料制备活性炭,结果表明,只要其灰分含量小于25%,就可以制备出性能较好的粒状活性炭.活性炭对苯的吸附容量达450mg·g-1,对水中对硝基苯酚的饱和吸附容量约为430mg·g-1,四氯化碳吸附率约54%,比表面积约1000m2·g-1,碘值700mgI2·g-1,可用于有机溶剂回收、空气与水的净化及作催化剂载体.Abstract: The paper studied the possibility of making activated carbon from coal slurry which was wasted by the process of coal washing.The research results showed that satisfactory granular activated carbon could be made from coal slurry so long as the ash content of the coal slurry was less than 25%.The activated carbon had 450mg C6H6·g-1 adsorption capacity, 430mg p-nitrophenol·g-1 adsorption capacity, 54% CCl4 activity, 1000 m2·g-1 specific surface area,700mg I2·g-1 iodine number.This activated carbon can be used for organic solvent recovery, gas/water purification and as the carries of catalysts.
