| 摘 要： | 据估计 ,美国每年有大约 2亿 5千万条废轮胎[1] ,中国约有 1亿条 ,香港约有 10 0万条。如何处理这样大量的废轮胎引起了一系列的环境与经济问题。目前 ,世界各国较常用的废轮胎处理方式可分为堆置和填埋、资源回收后的原型利用及粉碎再利用、作为能源利用的燃烧、热解及气化等。国内外虽然对废轮胎热解技术进行了一些研究[2～ 5] ,但以产气为目的的研究尚未被成功应用。废轮胎具有高挥发组份与低灰份等优点 ,产生的气体燃料可以贮存、运输又可方便地应用于锅炉或其它各种形式的燃烧器 ,而无需对现有设备进行改装。所以废轮胎气化技术是有效…

| Abstract: | This paper introduces the effect of dolomite and limestone on waste tyre pyrolysis. When waste tyre was pyrolyzed in 700?℃, the derived gases was passed through the catalyst zone in which the temperature was controlled at 700?℃, 800?℃and 900 ℃, respectively. It is found that both dolomite and limestone affect the product distribution of tyre pyrolysis with erhancing gas yield and effective absorption of H2S. The effect of these catalysts on tar cracking is obvious at 900 ℃, however, the life of catalyst is short. The product yields are about 40% for gas, 30% for liquid and 30% for char in the presence of dolomite and limestone. The result indicates that multi-use of the pyrolysed product is highly recommended. |
