摘　　要：以蜡下油/加氢裂化尾油混合物作为蒸汽裂解制乙烯装置原料,利用蒸汽裂解模拟试验装置研究其裂解性能,考察了蜡下油的掺入量、裂解温度和水油质量比对目标烯烃产物收率的影响。蜡下油/加氢裂化尾油混合原料的最佳蒸汽裂解工艺条件为:蜡下油掺入质量分数20%,裂解温度820℃,水油质量比0.75,此条件下产物乙烯、丙烯的收率分别为34.3%和14.65%。The steam cracking performance of the mixture was studied by using the mixture of foots oil and hydrocracking tail oil as feedstock of steam cracking unit for producing ethylene on a steam cracking simulation test device.The effects of foots oil amount,cracking temperature and water/oil mass ratio on the yield of target olefins were investigated.The results show that the optimum steam cracking conditions are as follows:the mass fraction of foots oil is 20%,the cracking temperature is 820℃,and the water/oil mass ratio is 0.75.Under these conditions,the yields of ethylene and propylene were 34.3%and 14.65%,respectively.
