  • Method for producing a separation product containing predominantly hydrocarbons with two carbon atoms
    Patent number: 11319264
    Abstract: The invention relates to a method (100) for the recovery of a separation product which contains predominantly hydrocarbons with two carbon atoms, with the use of a separation feedstock which contains predominantly methane, hydrogen and hydrocarbons with two carbon atoms, wherein the methane content of the separation feedstock is up to 20%, and the separation feedstock is provided in a gaseous state.
    Type: Grant
    Filed: August 14, 2017
    Date of Patent: May 3, 2022
    Assignee: LINDE AKTIENGESELLSCHAFT

  • Method and system for producing benzene
    Patent number: 11104624
    Abstract: A method (100) is proposed for the manufacture of benzene, in which a first feedstock mixture is formed, which contains alkylated aromatics and hydrogen, and in which the alkylated aromatics contained in the first feedstock mixture are partially converted with the hydrogen contained in the first feedstock mixture to the benzene through hydrodealkylation (33), thereby obtaining a first product mixture, wherein the first product mixture contains the benzene, the unconverted alkylated aromatics, alkanes with one to three carbon atoms formed in the conversion of the alkylated aromatics to the benzene, and the unconverted hydrogen, and wherein at least a part of the alkanes with one to three carbon atoms and of the hydrogen are separated from the first product mixture, thereby obtaining a light-gas fraction.
    Type: Grant
