原料中柴油组分对催化裂化装置产品分布的影响

Effect of Diesel Components in Raw Oil on FCC Production Distribution

为探索催化裂化柴油的深加工途径,中国石化洛阳分公司将催化裂化柴油回炼蜡油加氢装置,导致蜡油加氢装置的精制蜡油中柴油组分上升,进而提高了催化裂化装置原料中柴油组分含量。通过对比催柴进蜡油加氢装置回炼前后催化裂化装置产品分布的变化情况,说明原料中柴油组分上升不利于提高催化裂化装置的产品转化率。

In order to explore the deep processing of FCC diesel, FCC diesel was added to the wax oil hydrogenation unit, which led to the increase of diesel components in the refined wax oil, so that the content of diesel in raw oil of FCC unit was improved. By comparing the change of FCC product distribution through FCC diesel added to wax oil hydrogenation unit or not, it was indicated that the increase of diesel components in raw oil is not conductive to the conversion rate of FCC unit.
