白云石和石灰石對廢輪胎熱解產物的影響

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. 作 者： 陰秀麗    趙增立    徐冰燕    吳創之    陳勇    D.Y.C.Leung   作者單位： 陰秀麗,趙增立,徐冰燕,吳創之,陳勇(中國科學院廣州能源研究所,)
