城市固体生活垃圾微波裂解固体残留物制备活性炭

利用城市固体垃圾微波裂解固体残留物制备活性炭。固体残留物通过物理筛选，浮选的预分离，再用酸碱化学法将其中的杂质除去，然后用水蒸气物理活化法活化，最后制备出活性炭。对制备出的活性炭进行性能检测，结果显示：经过物理和化学分离提纯，原炭料碳含量由28．79％提高到81．50％；制备出的活性炭的吸碘值在587mg／g，比表面积591m2／g，亚甲值67mg／g。

PREPARATIONS OF ACTIVATED CARBON BY SOLID RESIDUES OF MUNICIPAL SOLID WASTE AFTER THE MICROWAVE PYROLYSIS

In this paper, solid residues of municipal solid waste（MSW）, which was disposed by the microwave pyrolysis,were used to prepare activated carbon by the predissociation of the physical screening and the flota- tion, removing the impurities in acid- base chemical methods, and activating the products in water vapor phys- ical activation. Performance testing of the activated carbon was researched. The results showed that the carbon content of the original carbon materials increased from 28.8% to 81.5% by the physical and chemical puri~ fications. The iodine absorption number of the activated carbon was 587mg/g, the specific surface area was 591m2/g and the methylene blue number was 67mg/g.
