摘　　要：为解决炼油厂延迟焦化装置加热炉炉管结焦的问题 ,根据结焦机理 ,研制了以表面活性剂为主 ,添加复合分散剂和有机络合物组分 ,与原料相适应的CAF 1延迟焦化加热炉阻焦剂 ,它无毒无味、不污染环境。工业应用的结果表明 :阻焦剂通过原料泵连续加注 ,在加注量为新鲜原料的10 0 μg/ g时 ,加热炉运行周期可由原来的 10 1d延长至 171d ;每年可获经济效益近 2 0 0万元。CAF-1 decoking agent was prepared with surface active agent added with complex dispersant and organic complex according to the coking mechanism for solving the problem of furnace tube coking in the refinery delayed coker. The said decoking agent was no toxity, odourless, non polluting and was compatible to the feedstock. The application result showed that by continuously adding 100μg/g (fresh feedstock basis), the running cycle was prolonged from original 101d to 171d. The economic profit was near 2 million yuan per year.
