  • Patent number: 11952323
    Abstract: The current disclosure relates to an apparatus and a process for producing poly-?-olefins (PAO), including reacting olefin monomers in a presence of a catalyst complex to form PAO product. The reaction is performed in a reaction including a reactor vessel and a system for recycling and cooling part of reactor outlet stream. At least one reactor is a cone reactor with a first cross sectional area in an upper part of the vessel and the cross sectional area decreases downwards to a second cross sectional area, which is smaller than the first cross sectional area.
    Type: Grant
    Filed: June 14, 2022
    Date of Patent: April 9, 2024
    Assignee: NESTE OYJ

  • Patent number: 9707511
    Abstract: The present description is related to the field of hydrocarbon production by gasification of carbonaceous material. It provides a two-stage gas washing method as a part of gas refining. More specifically it discloses a method for hydrogen sulfide and carbon dioxide removal from synthesis gas produced by gasification. It introduces a use of a novel combination of wash approaches for this application. As a specific application, this process is utilized as a part of biomass to liquid (BTL) process.
