Patent number: 10683459Abstract: Provided are a liquid-phase hydroisomerization system and a process therefor and use thereof. The system comprises a gas-liquid mixer (3), a hydroisomerization reactor (4) and a fractionating column (6). An oil product and hydrogen are mixed as a liquid hydrogen-oil mixture, and are introduced into the hydroisomerization reactor for a hydroisomerization reaction, and after being fractionated, a target product is led out. A supplemental hydrogen-dissolving inner member is provided at least between a group of two adjacent catalyst bed layers in order to supplement hydrogen to the reactants. The process cancels a circulating hydrogen compressor, has a simple process flow, and can be applied to the production of a lubricant base oil by the hydroisomerization of a lubricant raw material or the production of a low freezing point diesel by the hydroisomerization of and the reduction in the freezing point of a diesel raw material.Type: GrantFiled: June 8, 2016Date of Patent: June 16, 2020Assignee: PetroChina Company LimitedInventors: Shoutao Ma, Xiaoqiao Huang, Famin Sun, Qingfeng Ma, Fangming Xie, Yongsheng Duan, Xianjun Wu, Fengxuan Li, Dongmei Ge, Endong Xia, Ruifeng Li, Ronglei Ji, Liying Liu, Lihong Qin, Xiangbin Meng, Chunming Dong, Xuefeng Lu, Rui Wang, Tiegang Xu, Shurong Ni

Patent number: 10258965Abstract: The present invention relates to a method for preparing a sulfur-resistant catalyst for aromatics saturated hydrogenation, comprising the steps of: preparing noble metal impregnation solutions from a noble metal and deionized water or an acid solution; impregnating a carrier with the impregnation solutions sequentially from high to low concentrations by incipient impregnation; homogenizing, drying, and calcinating to obtain the sulfur-resistant catalyst for aromatics saturated hydrogenation. The catalyst for aromatics saturated hydrogenation prepared by the method according to the present invention is primarily used in processing low-sulfur and high-aromatics light distillate, middle distillate, atmospheric gas oil, and vacuum gas oil.Type: GrantFiled: December 9, 2015Date of Patent: April 16, 2019Assignee: PETROCHINA COMPANY LIMITEDInventors: Xiaodong Yang, Yanfeng Liu, Sheng Hu, Chunmei Yu, Hongling Chu, Xinmiao Wang, Shanbin Gao, Bin Xie, Famin Sun, Wencheng Zhang, Jintao Guo, Quanguo Zhang, Lili Jiang, Xiaofeng Wang, Yuanyuan Ji, Ran Sun, Yuxiao Feng, Xianjun Wu, Guojia Zhang, Tan Zhao, Wenyong Liu, Rui Li, Ruifeng Li, Cheng Tang

Patent number: 9534178Abstract: A hydrogenation method and distillate two-phase hydrogenation reactor in which the size of an upper space of the reactor is greater than that of a lower catalyst bed part. The reactor comprises 2 to 4 catalyst beds. An inner component for gas replenishment and for stripping a liquid-phase stream containing impurities is arranged between at least one adjacent catalyst bed and comprises a separator plate and exhaust pipes. The separator plate is provided with multiple downcomer through holes. The separator plate is connected with a plurality of exhaust pipes. The exhaust pipes are vertically arranged above the separator plate. The top parts of the exhaust pipes are in contact with the lower part of the upper catalyst bed.Type: GrantFiled: August 1, 2013Date of Patent: January 3, 2017Assignee: PETROCHINA COMPANY LIMITEDInventors: Shoutao Ma, Ran Tian, Zhihua Zhang, Gang Wang, Famin Sun, Ruiqin Zhang, Chunmei Yu, Shengbo Sun, Xiufang Feng, Fengxuan Li, Jinling Zhu
