摘要
研究了废轮胎热解的规律和热解油作为捕收剂的煤泥浮选效果。试验结果表明：热解最终温度影响比较显著，而起始温度和保温时间对废轮胎热解油回收率影响不显著。FT—IR分析表明：东庞煤中含有大量的长链烃、芳香结构，还有-C=C-、-C=O、-OH、-SO2、-NH和-NH2。热解油中富含芳烃、烯烃、烷烃和一定量极性物。煤泥浮选表明：热解油作为煤泥捕收剂具有较强的捕收性能，同时还具有一定的起泡性能，可明显减少起泡剂用量。
Study the pyrolytic rule of waste tyre and the flotation effect of the pyrolytic oil. The pyrolysis results show that：the final pyrolysis temperature has remarkably ＇affection, while the initial temperature and holding time on recovery of pyrolytic oil are less influential. FT-IR analysis show that： Dongpang coal contains large amounts of long-chain hydrocarbons, aromatic structure, as well as -C=C-,-C=O,-OH ,-SO2 ,-NH and -NH2. Pyrolytic oil is rich in aromatics, olefins, alkanes, and a certain amount of polar material. The results of coal flotation show that：pyrolytic oil as collector has strong collecting performance, but also has some blistering performance, it can significantly reduce the amount of foaming agent.
