摘　　要：用 1 L反应器在煤油比为 1∶ 1 ,在 40 0℃～ 45 0℃的温度范围内 ,研究了温度对共处理反应及沥青性质的影响 .在实验条件下 ,沥青产率最高 .保持同一蒸油温度时 ,所得共处理沥青随反应温度的增加沥青性质发生了有规律的变化 .随温度的增加 ,沥青分子量逐渐下降 ,软化点逐渐下降 .这归结为沥青分子中分子量 >1 0 0 0的分子含量下降 .共处理沥青具有一定的延度 .流变性规律显示 40 0℃时共处理沥青与 Shell 90 #The coprocessing reaction of coal and catalytic residue(CCR),especially the asphalt produced were studied in 1 L autoclave when the ratio of coal to CCR is 1/1.The yield of asphalt is the highest among the other products.The properties of the asphalt changes regularly with the variation of reaction temperature.Average molecular weight and softening point decreased with the increasing of reaction temperature.It was due to the decrease of the amount of molecular with a average molecular weight greater than 1 000.Furthermore it was also found that the asphalt produced from coprocessing shows the similar rheology property as commercial paving asphalt Shell 90 #.Coprocessing asphalt present a good ductility which is necessary for further utilization.It may be used as high grade paving asphalt for highway and a pitch precursor of carbon artifacts
