Patent number: 11981628Abstract: Use of a method for reduction of heavy end formation and catalyst loss in a hydroformylation process, wherein the method comprises the steps; a) Reacting an olefin and syngas in a reactor assembly (1) utilizing at least one catalyst and at least one ligand, b) Separating an obtained aldehyde from a mixture of aldehyde, catalyst, ligand and early heavy ends in a distillation unit (2), c) Entering the mixture of catalyst, ligand, early heavy ends and rest aldehyde into a short residence time evaporator unit (3) having at least a first rest aldehyde stripper stage (3a) and at least one last early heavy ends stripper stage (3b). Said evaporator units (3) being of a falling film and/or wiped film type, d) That the catalyst/ligand mixture from a lower end (3b1) of the at least one last early heavy ends stripping stage (3b) is entered into a cooling unit (4) immediately after stripping of early heavy ends.Type: GrantFiled: June 12, 2020Date of Patent: May 14, 2024Assignee: PERSTORP ABInventors: Matias Kangas, Stefan Nilsson

Patent number: 11981632Abstract: Disclosed is a method for producing hydrogen, carbon, and ethylene from a methane-containing feedstock even without recycling of unreacted methane by providing a single process or system in which a methane-containing feedstock is subjected to two methane conversion steps. The method includes a first conversion step of producing hydrogen and carbonaceous materials and a second conversion step of producing acetylene from unreacted methane and hydrogen discharged from the first conversion step while maintaining a good methane conversion and suppressing coke formation, followed by separating and recovering ethylene and hydrogen produced through selective hydrogenation of acetylene.Type: GrantFiled: October 28, 2022Date of Patent: May 14, 2024Assignee: SK Innovation Co., Ltd.Inventors: Dong Min Yun, Hee Soo Kim, Ji Hoon Lee, Jung Geun Jang, Dae Hyun Choo
