摘要：

利用分析仪器和裂解炉模拟实验装置对4种原料[原料1(国内石化企业的加氢尾油)、原料2（合资石化企业含有柴油的加氢尾油）、原料3（国内石化企业含有柴油的加氢尾油）、原料4（国内石化企业的柴油）]的组成以及裂解性能进行了研究。裂解反应的实验条件:裂解炉出口温度为780～820 ℃，裂解炉出口压力为0.08 MPa，裂解炉停留时间为0.24 s ，水油比为0.8。裂解反应的实验结果表明，裂解产物的三烯（乙烯、丙烯和丁二烯）收率排序：原料1 >原料2>原料3>原料4。4种原料的经济效益：原料1 >原料2>原料3>原料4。综合评价可知，在现有工业装置条件下，将加氢尾油和柴油的混合原料（原料2和原料3）用作裂解原料是一种切实可行的方法。

Abstract:

The composition and pyrolysis performance of four kinds of feedstock were studied by using analytical instruments and pyrolysis furnace simulation experimental apparatus. Feedstock 1 is hydrocracking tail oil from domestic petrochemical enterprises, feedstock 2 is hydrocracking tail oil containing diesel oil from joint-venture petrochemical enterprises, feedstock 3 is hydrocracking tail oil containing diesel oil from domestic petrochemical enterprises, and feedstock 4 is diesel oil from domestic petrochemical enterprises. The experimental conditions of pyrolysis reaction are as follows: the outlet temperature of pyrolysis furnace is 780～820 ℃, the outlet pressure of pyrolysis furnace is 0.08 MPa, the residence time of pyrolysis furnace is 0.24 s, and the water oil ratio is 0.8. The results showed that the order of the yield of ethylene, propylene and butadiene was as follows: feedstock 1 > feedstock 2 > feedstock 3 > feedstock 4. The order of the economic benefit of the four kinds of feedstock are as follows: feedstock 1 > feedstock 2 > feedstock 3 > feedstock 4. Comprehensive evaluation shows that it is a feasible method to use the mixed feedstock (feedstock 2 and feedstock 3) of hydrocracking tail oil and diesel oil as the cracking feedstock under the conditions of existing industrial plants.
