摘要
研究了以锯木屑、纸张和塑料的热解物为原料制备中孔活性炭过程中塑料热解物所起的作用。结果表明:在料条制备过程中,塑料热解物具有润滑、粘结作用,可有效地减少焦油粘结剂的用量;在料条炭化阶段,由于塑料热解物的热解、析出,使炭化料条具有发达的孔隙(闭合)结构,最终使在随后的活化过程中加快活化反应速度,提高活性炭的吸附性能;塑料热解物在活性炭孔结构的形成和发展过程中,具有一定的调节作用。
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.
