MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517058070 A) filed by Topsoe A/S, Lyngby, Denmark, on June 17, for 'a process for recovery of hydrogen during hydroprocessing of a feedstock comprising oxygenates.'
Inventor(s) include Andersen, Stefan.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a process for hydroprocessing a feedstock comprising oxygenates, comprising the steps of a. directing said feedstock, an amount of make-up hydrogen and a recycle gas to contact a catalyst active in hydroprocessing under active hydroprocessing conditions, to provide a hydroprocessed product stream, b. separating from the hydroprocessed product stream a vapor product fraction and a liquid product fraction by gas liquid separation at a pressure above 80% of said active hydroprocessing conditions and a temperature above 200 C, c. separating from the vapor product fraction a gaseous product fraction and a light liquid product fraction by gas/liquid separation at a pressure above 80% of said active hydroprocessing conditions and a temperature below 100 C, d. directing at least an amount of said gaseous product fraction to a means of gas purification to provide a hydrogen rich gas fraction depleted in molecules with a molecular weight above 12 g/mole and a hydrogen depleted gaseous fraction enriched in molecules with a molecular weight above 12 g/mole, e. providing at least an amount of said hydrogen rich gas fraction as a portion of said recycle gas or make-up hydrogen. This has the associated benefit of providing a pure recycle gas also for partially hydroprocessed product streams, which have a low capacity for capturing CO2, CO and CH4."
The patent application was internationally filed on Dec. 21, 2023, under International application No.PCT/EP2023/087197.
