摘　　要：针对釜式空气氧化改质系统,分析了烟气析出排放过程的内部机理,提出了煤沥青空气氧化过程中烟气挥发速率模型,通过积分法对模型进行变换,并用作图法检验模型.在空气用量为1.0 L/min,氧化温度分别为340,360和380℃的条件下制取了氧化沥青,并得到这3种条件下的模型参数分别为0.085 8,0.124 1和0.140 4.试验结果表明该模型是合理可靠的.The modification mechanism was studied based on the system of air blowing modification of coal tar pitch. A rate model of distilled gas from air blowed coal tar pitch was proposed, which was transformed with an integral method and rearranged with a linear dependence. The oxidized tar pitch was prepared at the air blowing rate of 1.0 L/min and the temperatures of 340, 360 and 380 ℃. The related model parameters of 0. 085 8, 0. 124 1 and 0. 140 4 were obtained from the ratio of slope. The experimental results show that the model was reasonable and reliable.
