Processing method of diesel raw oil

The invention discloses a method for simultaneously producing a low-carbon olefin cracking raw material and a hydrocracking/catalytic cracking raw material by taking diesel raw oil as a raw material. Compared with a method of firstly performing hydrogenation and then performing extraction, the method of firstly performing extraction and then performing hydrogenation can avoid excessive saturation of aromatic hydrocarbon in the process of firstly performing hydrogenation and can avoid excessive saturation of aromatic hydrocarbon in the process of firstly performing hydrogenation, and by adopting the method of firstly performing extraction, the extracted raw materials respectively enter a hydrogenation reactor, so that the hydrogenation depth can be controlled according to the requirements of products. 本发明公开了一种以柴油原料油为原料，同时生产低碳烯烃裂解原料以及加氢裂化/催化裂化原料的方法。采用先抽提后加氢的方法，与先加氢后抽提的方法相比，可以避免芳烃在先加氢过程中的过度饱和，可以避免芳烃在先加氢过程中的过度饱和，采用先抽提的方法，抽提后的原料分别进入加氢反应器中，可根据产品的需要控制加氢的深度。
