Publication number: 20240059568Abstract: An apparatus, a process and a system for treating petroleum coke are provided. The apparatus includes an activation unit that is an annular furnace reactor. The system includes a first reactor, the apparatus as a second reactor, a washing and separating unit, a cooling unit, a dissolving and separating unit, a washing and drying unit, optionally a regenerating unit, optionally a drying and calcining unit and optionally an evaporation-crystallization unit. The process for producing carbon materials uses the system for treating petroleum coke. The apparatus, the process and the system can achieve continuous production, and have advantages of high activation efficiency and stable properties of the resultant carbon material products.Type: ApplicationFiled: January 10, 2022Publication date: February 22, 2024Inventors: Shudong ZHANG, Changan ZHANG, Yongyi SONG, Jihua LIU, Xiangchen FANG, Rui MA, Haile CAI, Liping ZHAO, Changjian LIAO, Fanfei MENG, Haibo WANG, Qingjun ZHANG, Chao WANG

Patent number: 9382489Abstract: More stable and valuable bio-oil produced from biomasses are provided. More specifically, more stable and valuable bio-oil useful as heating oil, alone or in combination with an oxygenated acyclic component, is provided. Particularly, various embodiments of the present invention provide for a bio-oil having sufficient heating value and stability to be useful as heating oil, alone or in combination with an oxygenated acyclic component, without the need to hydrotreat the bio-oil or use a similar deoxygenating process.Type: GrantFiled: January 13, 2014Date of Patent: July 5, 2016Assignee: Inaeris Technologies, LLCInventors: Maria Magdalena Ramirez-Corredores, Vicente Sanchez, Changan Zhang

Patent number: 8506658Abstract: A process and system for separating a light fraction, a bio-distillate fraction, and a heavy fraction from a bio-oil, and for producing a renewable distillate including at least in part the bio-distillate fraction and a stabilizing additive, is provided. The process comprises separating bio-oil into light, bio-distillate, and heavy fractions based on their boiling points. At least a portion of the bio-distillate fraction and a stabilizing additive are blended with a petroleum-derived-diesel-range stream, without any prior hydrotreatment, to thereby provide a renewable distillate composition.Type: GrantFiled: June 26, 2012Date of Patent: August 13, 2013Assignee: KiOR, Inc.Inventors: Maria Magdalena Ramirez Corredores, Jennifer Sorrells, Changan Zhang
