摘　　要：利用由结构导向集总新方法构建的延迟焦化动力学模型计算了渣油掺炼废道路沥青的共焦化效果。结果表明,废道路沥青能够作为延迟焦化掺炼原料。小试试验结果表明,在470℃、0.15 MPa、零循环比条件下.80%渣油和20%废道路沥青共焦化比全渣油焦化产物收率的80%高,其中气体收率高出2.3百分点,液体收率高出2.91百分点,焦炭收率高出14.79百分点。通过焦化产物性质对比和经济性估算证实,废道路沥青作为延迟焦化掺炼原料是其再利用的一条新途径。The coking of a mixture containing residue oil and waste road asphalt was calculated by a delayed coking kinetic model built by structure oriented lumping method, and the results showed that waste road asphalt could be used as a blending material for delayed coking. Experimental results indica ted that under the operating conditions of 470 ℃, 0.15 MPa and without recycle, as compared with the 80%yields of total residue oil coking, for coking of this residue oil mixed with 20% waste road asphalt, the yield increase of gas, liquid and coke was 2.30, 2.91 and 14.79 percentage point, respectively. By comparing products properties and economic estimation, it was confirmed that waste road asphalt as delayed coking blending material could be a new approach for its recycling.
