循环流化床内废轮胎的热解油化

介绍了以循环流化床反应器为主体的废轮胎热解油化装置，实验过程，实验结果及分析。通过评价热解条件对气体成分及油、碳和气产物产率的影响，以及热解油品的成分分析，得出如下结论：（１）较高的温度和较好的停贸时间会生成过多的不凝气（主要成分为ＣＨ４、Ｈ２，Ｃ２ＨＶ和ＣＯ等），降低油的产率，过低的温度和加热速率导致严重的碳化，同样会降低油产率。（２）热解油品的组成成分非常复杂，芳烃占了很大比例，其次是烷烃和非

PYROLYSIS OF WASTE TIRES IN CFB REACTOR

With the CFB as main reactor, an integrated facility was developed for the pyrolysis of waste tires, in which the main chemical processes can be modelled and the bed is divided into two zones corresponding to the pyrolysis and second reactions Based on the effects of pyrolysis conditions on the gas composition and the yields of char, gas and oil, analysis of the experimental data shows the important effects of temperature, heating rate and residence time The main trend is that (1) the higher temperature and longer residence time contribute to the secondary reaction; and (2) the lower heating rate favors the carbonization, both of which reduce the oil production The component analysis of pyrolysis oil indicates that most compounds in oil are aromatics, then non-hydrocarbons and alkanes, while bitumen is relatively low
