Intellectual Property India Publishes Patent Application for 'Process And Plant For The Conversion Of Oxygenates To C5+ Hydrocarbons Boiling In The Jet Fuel Boiling Range' Filed by Topsoe A/S

MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517080858 A) filed by Topsoe A/S, Lyngby, Denmark, on Aug. 26, for 'process and plant for the conversion of oxygenates to c5+ hydrocarbons boiling in the jet fuel boiling range.'

Inventor(s) include Joensen, Finn; Sorensen, Martin Dan Palis; Kaarsholm, Mads Kristian; Beato, Pablo; Hidalgo Vivas, Angelica; and Burn, Jeremy Neil.

The application for the patent was published on Oct. 10, under issue no. 41/2025.

According to the abstract released by the Intellectual Property India: "Process and plant for the conversion of oxygenates to hydrocarbons boiling in the jet fuel boiling range, comprising the steps of continuously: a) providing one or more feed streams of one or more oxygenate compounds; b) heating the one or more feed streams to an inlet temperature of a first set (R1) of one or more downstream adiabatic fixed bed reaction zones; c) introducing the one or more heated feed streams (1) into inlet of R1; d) converting in the one or more adiabatic fixed bed reaction zones of R1 the one or more heated feed streams in the presence of a conversion catalyst comprising a zeolite with a framework having a 10-ring pore structure, said 10-ring pore structure being a unidimensional (1D) pore structure, to a converted-oxygenate product comprising C5+ hydrocarbons of which at least 30 wt% are said hydrocarbons boiling in the jet fuel boiling range; wherein said 1-D pore structure is any of *MRE (ZSM-48), MTT (ZSM-23), TON (ZSM-22), or combinations thereof, the content of phosphorous (P) in the conversion catalyst is 0.1-3 wt%; e) withdrawing from the one or more adiabatic fixed bed reaction zones the converted-oxygenate product; f) determining at outlet of the one or more adi- abatic fixed bed reaction zones an amount of one or more unconverted oxygenate com- pounds in the withdrawn converted-oxygenate product; g) continuously adjusting the in- let temperature of the one or more feed streams in step b to maintain a constant amount of the one or more unconverted-oxygenate compounds as determined in step f of between 10 and 4000 ppmv."

The patent application was internationally filed on Mar. 26, 2024, under International application No.PCT/EP2024/058096.
