Production of Activated Carbon from Municipal Solid Organic Wastes

城市垃圾先热解再焚烧可大大提高垃圾的焚烧效率,中孔活性炭则可有效地吸附垃圾焚烧过程中所产生的剧毒有机物-二恶英.基于此,该论文在对城市垃圾中各组分性质分析的基础上,首次提出了利用垃圾中三种典型的固体有机废弃物-木质类、纸张、塑料的热解产物为原料制备适宜于吸附二恶英的中孔发达活性炭的垃圾综合利用新工艺.该文最后考察了废弃物基活性炭对甲苯的吸附特性.结果表明,Langmuir方程和Yoon理论分别对废弃物基活性炭吸附甲苯时的等温吸附行为和吸附动力特性进行很好地描述,同时废弃物基活性炭吸附甲苯穿透时间的对数分别与入口浓度的对数及气体流量具有良好的线性相关性

factorsaffectingtheadsorbabilityofactivatedcarbonsproducedfrommunicipalsolidorganicwaste

Activated carbons were prepared by steam activation of pyrolysis products from three typical municipal solid organic wastes (MSOW), sawdust (S), paper (PA), plastics (PL) and their mixtures. Factors affecting their adsorbability were investigated. Results show that the adsorbability of MSOW based activated carbons increases with an increase of the ratio of S to PA under a constant fraction of PL, whereas the adsorbability decreases with an increase of the PL content at a constant ratio of S to PA. In addition, the adsorbability of MSOW based activated carbons exhibits a maximum with increasing pyrolysis temperature

城市固体有机废弃物制备中孔活性炭

研究了以锯木屑、纸张、塑料的热解物（分别简称木炭、纸炭、塑料热解物）为原料制备中孔活性炭时孔结构发展的影响因素。结果表明：当塑料热解物含量一定时，木炭、纸炭组成比的改变主要对活性炭的微孔产生影响，即二者的组成比越高，活性炭的微孔孔容越大；塑料热解物含量是活性炭中孔形成的主要影响因素，随着塑料热解物含量的增加，活性炭的中孔孔容先增加再减少；低的热解温度有利于活性炭顺孔结构的形成和发展；最后对中孔形成的机理进行了探讨

钙化物在废弃物基活性炭制备过程中的影响

研究了以城市垃圾中3种典型的固体有机废弃物——锯木屑、纸张和塑料的热解产物（分别简称木炭、纸炭和塑料热解物）为原料，水蒸气为活化剂制备废弃物基活性炭时钙化物含量对活化过程、活性炭吸附性能（以碘值表征）及其孔结构的影响。结果表明，钙化物可加快活化反应的速度，且钙化物含量在1.5%时活化反应速度即已不再随钙化物含量的增加而增加；活性炭的吸附性能则随钙化物含量的增加而减少，同时钙化物对活性炭的孔径分布基本无影响，但降低了活性炭的比表面积、微孔孔容及中孔孔容；钙化物的2种前驱体（即CaO和Ca（OH）2）对活化过程具有相同的催化作用

塑料热解物在城市有机废弃物制备活性炭中的作用

The role of plastic pyrolysis products (PPP) in the preparation of activated carbon from three typical municipal solid organic wastes (MSOWs: sawdust, paper and plastic) was investigated. The results show that the PPP can not only be used as a raw material for activated carbon prepared from MSOWs, but also can effectively decrease the amount of tar addition required to produce a cylindrical bar because of its adhesive property. The release of the PPP from the bar during carbonization causes the carbonized bar to have more slit pores, which increase activation rate and improve adsorbability of the activated carbon. The PPP also plays an adjusting role in the pore formation and pore development, especially in mesopore development
