摘　　要：某石化企业生产的催化裂化柴油(LCO)、C_(10)+重芳烃(HAB)产量大,性质差。为解决重芳烃油加工难问题,将部分LCO和HAB改至焦化汽柴油加氢装置进行加工,并开展了不同比例下掺炼重芳烃油工业试验,对比分析不同工况下原料性质、主要操作参数、产品性质、物料平衡等方面数据的变化。结果表明,在入口氢分压7.0 MPa、入口氢油体积比530~580条件下,掺炼约8%HAB后,可以得到硫质量分数7.3μg g、十六烷值49.2、多环芳烃质量分数6%的优质柴油调合组分。在低压、低氢油比条件下,较低反应温度即可使得芳烃饱和反应达到平衡,并可根据平衡转化率调整重芳烃掺入量。The catalytic diesel and C 10+heavy aromatics produced by a petrochemical enterprise have a large output and poor properties.In order to solve the problem of difficult processing of heavy aromatics oil,some FCC diesel and C 10+heavy aromatics were modified to the coker gasoline diesel hydrogenation unit for processing.Industrial experiments were conducted on blending heavy aromatics oil at different ratios,and the changes of raw material propertyies,main operating parameters,product properties,material balance and other data under different operating conditions were compared and analyzed.The results showed that when the inlet hydrogen partial pressure was 7.0 MPa and inlet hydrogen oil volume ratio was 530-580,after blending about 8%heavy aromatic oil,the diesel blending component with a sulfur mass fraction of 7.3μg g,a cetane number of 49.2 and a polycyclic aromatic hydrocarbon content of 6%was obtained.Under the conditions of low pressure and low hydrogen oil ratio,the saturation of aromatics can reach equilibrium at low reaction temperature,and the amount of heavy aromatics can be adjusted according to the equilibrium conversion rate.
