| 摘 要： | 采用真空热裂解的方法处理含油污泥,研究热解终温、体系压力、保温时间和冷凝温度对热解产物产率的影响。实验结果表明:在热解终温为500℃,体系压力为10 kPa,保温时间为30 min,冷凝温度为-20℃的条件下,可得到热解固体渣、热解液和热解气的产率分别为9.4%,85.8%和4.8%;分离热解液的水分后得到油产率为原含油污泥的31.25%;采用真空热裂解的方法,能实现含油污泥全组分清洁循环利用。

| Abstract: | The vacuum pyrolysis of oil sludge was investigated.The effects of technical conditions such as final pyrolysis temperature,system pressure,holding time and condensation temperature were discussed in details.The experimental results show that when vacuum pyrolysis is carried out at pyrolysis temperature of 500 ℃,system pressure of 10 kPa,holding time of 30 min,condensation temperature of ?20 ℃,the yields of pyrolysis solid,pyrolysis liquid and pyrolysis gas are 9.4%,85.8% and 4.8%,respectively.After separation of water from pyrolysis liquid,pyrolysis oil with the content of 31.25% of oil sludge can be obtained.All the materials from oil sludge can be satisfactorily recycled by vacuum pyrolysis. |
