Abstract: Methods and systems for producing diesel arc provided. The method for producing diesel can include cracking a first hydrocarbon Iced in a first riser under first cracking conditions to provide a first effluent containing a first light cycle oil, a heavy cycle oil, and a first bottoms and fractionating at least a portion of the first effluent to separate the first bottoms and the heavy cycle oil from the first light cycle oil. The method can include cracking the separated first bottoms in a second riser under second cracking conditions to produce a second effluent containing a second light cycle oil and a second bottoms. The method can also include cracking the separated heavy cycle oil in the first riser under third cracking conditions to provide a third effluent and mixing the third effluent with the first hydrocarbon feed to provide the first cracking conditions.

Abstract translation: 提供生产柴油电弧的方法和系统。 生产柴油的方法可以包括在第一裂解条件下在第一提升管中裂解第一烃离子，以提供含有第一轻循环油，重循环油和第一塔底馏分的第一流出物，并分馏至少一部分第一 流出物从第一个轻循环油分离第一个底部和重的循环油。 该方法可以包括在第二裂解条件下在第二提升管中裂解分离的第一塔底物，以产生含有第二轻循环油和第二塔底物的第二流出物。 该方法还可以包括在第三裂解条件下在第一提升管中裂解分离的重质循环油以提供第三流出物并将第三流出物与第一烃进料混合以提供第一裂解条件。
