RS-2100和RHC-133B在1.0 Mt/a柴油加氢改质装置的工业应用

为了适应当前市场需求变化,降低柴汽比,增产石脑油,中国石油辽阳石化分公司1.0Mt/a柴油加氢精制装置改造为1.0 Mt/a柴油加氢改质装置,采用中国石化石油化工科学研究院开发并由中国石油抚顺石化分公司催化剂厂生产的预硫化态的RS-2100精制催化剂和RHC-133B改质催化剂,加工直馏柴油生产收率不低于11％的石脑油...

COMMERCIAL APPLICATION OF CATALYSTS RS-2100 AND RHC-133B IN 1.0 Mt/a DIESEL HYDROUPGRADING UNIT

In order to adapt to the change of current market demand,reduce the ratio of diesel to gasoline and increase the output of naphtha,a diesel hydrofining unit with a capacity of 1.0 Mt a of PetroChina Liaoyang Petrochemical Company was transformed into a 1.0 Mt a diesel hydroupgrading unit.The pre-sulfurized refining catalyst RS-2100 and hydroupgrading catalyst RHC-133B developed by SINOPEC Research Institute of Petroleum Process and produced by the catalyst factory of PetroChina Fushun Petrochemical Company of were used to produce naphtha with a yield not less than 11%and the ChinaⅥdiesel fuel from straight-run diesel.In the process of start-up,the drying and catalyst activation was combined for the device,which greatly shortened the start-up time and was successfully started up in July 20,2019.The device was calibrated from September 23 to 26,2019.The calibration results showed that the naphtha average yield was more than 11.5%,and the aromatic potential content of the naphtha reached 50%,which could be used as reformer feedstock.Meanwhile,the cetane number of the produced diesel fuel increased by 3.5 with the mass fraction of polycyclic aromatics less than 7%and the mass fraction of sulfur less than 5μg/g,meeting the ChinaⅥdiesel standard.
