摘　　要：通过模拟实验,对大庆石化重烃-石脑油混合原料裂解性能进行了优化研究,考察了在SC-1型裂解炉中重烃质量分数分别为30%、35%的条件下,工艺参数对目的产物收率的影响。实验结果表明,重烃(质量分数30%、35%)-石脑油原料在SC-1型裂解炉中裂解,适宜的裂解温度均为850℃,水油质量稀释比为0.5时,三烯收率分别为53.78%、54.39%,重烃-石脑油混合裂解性能与石脑油单独裂解性能相近。重烃(质量分数35%)-石脑油原料裂解的模拟实验数据已应用于工业裂解炉中,使乙烯收率提高0.48%,三烯收率提高0.15%。Through simulation experiments, the optimization on pyrolysis performance with heavy hydrocarbons and naphtha from Daqing Petrochemical Company as materials is studied. The effect of process parameters on target product yield is investigated with 30% and 35% of heavy hydrocarbons content （ all the content was expressed with mass fraction） in the SC-1 cracking furnace. The experiment results show that when the hydrocarbons content （30%, 35% ） and naphtha cracked in the SC-1 cracking furnace, the triene yields can be reached 53.78% and 54. 39% ,respectively, under the conditions as follows：850℃ of proper cracking temperature and 0. 5 （ω水/to油） of dilution ratio. The pyrolysis performance of heavy hydrocarbons and naphtha is similar to that of naphtha alone. The simulation experiment data has been used in industrial cracking furnace, so that the yield of ethylene and triene is increased by O. 48 % and 0. 15 %, respectively.
