MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617064441 A) filed by Neste Oyj on May 21, 2026, for Hydroliquefaction Of Carbonaceous Feedstock.

Inventors include Nurmi, Pekka; Aho, Marjut; Kangas, Jani; Burman, Anton; Noopila, Iina; and Mnttri, Esa.

The application for the patent was published on June 12, 2026, under issue no. 24/2026.

Abstract: Herein is described a method for the production of liquid hydrocarbon composition, comprising i) providing carbonaceous feedstock (a); ii) subjecting the carbonaceous feedstock (a) to catalytic hydroliquefaction (10) in the presence of hydrogen to obtain a product mixture comprising liquid hydrocarbons and off-gas; iii) separating (20) the liquid hydrocarbons and the off-gas to obtain a first liquid fraction (b-1) and a first gaseous fraction (c-1) iv) converting (30) in gas phase at least part of the light oxygenates comprised in the first gaseous fraction (c-1) and v) converting in the presence of water steam at least part of the carbon monoxide (CO) comprised in the first gaseous fraction (c-1) and/or produced in step iv) to carbon dioxide (CO2) and hydrogen (H2) by water gas shift reaction, to obtain a CO2 and H2 enriched first gaseous fraction (c-1e); and vi) separating (40) non-condensables from the CO2 and H2 enriched first gaseous fraction (C-1e) to obtain a second gaseous fraction (c-2) and a second liquid fraction (b-2); vii) recovering (50) at least part of H2 from the second gaseous fraction (c-2) and recirculating at least part, of the recovered H2 to step ii); viii) recovering the first liquid fraction (b-1) and/or the second liquid fraction (b-2) to provide a liquid hydrocarbon composition.
