| 摘 要： | 以新疆克拉玛依油田采油污泥为对象，分别采用热重分析仪和小型流化床热解反应器研究了含油污泥的热解过程及其热解效果。结果表明，油泥热解主要经历了失水、轻质组分挥发、重组分快速热解失重和缓慢失重4个阶段，热解过程基本符合一级动力学方程，提高热解的升温速率，可使油泥的最大失重速率Dmax、失重速率峰值温度θmax、升温终点的最大失重率都随之增加，表现在动力学上，反映出表观活化能和碰撞频率因子的同时升高，即提高油泥热解转化率的同时也影响了热解效率。失水油泥用流化床热解，在热解温度600℃、反应时间3 min时，油泥回收率可达到87%。 |

| Abstract: | The pyrolysis process and efficiency of oil exploitation sludge in the Karamay Oilfield were studied with thermogravimetric analysis apparatus and a small fluidized bed pyrolysis reactor.The thermogravimetric results show that the oil sludge by pyrolysis has undergone four stages:water loss,the volatile of the lightweight components,rapid weight loss and slow weight loss.The study on the thermal dynamics shows that the pyrolysis of oil sludge accords generally with one reaction model.The characteristic para... |
