摘　　要：分析了延迟焦化装置加热炉结焦的原因,对其结焦机理进行了探索,在机理研究的基础上开发了CAF型焦化加热炉阻焦剂。实验室评价和工业应用试验结果表明,该剂可有效阻止和延缓焦垢在加热炉管内壁形成和沉积,延长炉管烧焦周期46％以上。Causes of coking in the heater of delayed coker have been analyzed and the mechanism of coke formation has been studied. On the basis of the analysis, CAF anti-coking agent has been developed. Laboratory evaluation and the commercial application show that CAF anti-coking agent has the excellent performance in suppressing and retarding coke formation in the heater of delayed coker. Coking-burning period of the heater tube has been prolonged by more than 46% .
