Method for producing petrochemical products by hydrotreating recycle oil

In accordance with one or more embodiments, methods of producing petrochemical products from hydrocarbon materials are currently disclosed. The process can include separating a hydrocarbon material into at least a lower boiling fraction and a higher boiling fraction, cracking at least a portion of the higher boiling fraction, cracking at least a portion of the lower boiling fraction, separating a recycle oil from one or both of a first cracking reaction product or a second cracking reaction product, and separating the recycle oil from one or both of the first cracking reaction product and the second cracking reaction product. The recycle oil is hydrotreated to form a hydrotreated recycle oil, and the hydrotreated recycle oil is recycled. 根据一个或多个实施方案，目前公开了从烃材料生产石化产品的方法。所述方法可包括将烃材料至少分离成较低沸点馏分和较高沸点馏分，裂化较高沸点馏分的至少一部分，裂化较低沸点馏分的至少一部分，从第一裂化反应产物或第二裂化反应产物中的一者或两者中分离循环油，加氢处理循环油以形成加氢处理的循环油，以及再循环加氢处理的循环油。
