摘　　要：介绍了阻焦剂的阻聚分散机理 ,测定了含有不同组分的高温阻焦剂对胜炼催化原料的的阻焦效果 ,并考察了不同加入浓度对阻焦率以及催化裂化产品分布的影响。试验结果表明 :加入 ( 5 0～ 15 0 )× 10 - 6 的阻焦剂 ,可使催化裂化阻焦率达到 5 3 .7%～ 75 .8% ,同时对产品分布及产品性质无不良影响 ,具有技术经济可行性。Polymerization retarding and dispersing mechanism of anti-coking agent is presented together with the effect of high temperature anti-coking agent with different compositions on different property feedstock in Shengli Refinery. Influence of different concentration anti-coking agent on the anti-coking rate and catalytic cracking product slate has been investigated. The test result shows that anti-coking rate of FCC unit has reached 53.7%～75.8% by adding (50～150)×10 -6 anti-coking agent, without negative effect on product slate and product property. It is feasible both technically and economically.
