Patent number: 11987754Abstract: The present disclosure relates to a process for converting a combined feedstock to renewable liquid product(s), wherein the ash content of the combined feedstock of lignin feedstock and a second renewable feedstock is low. The combined feedstock is mixed with solvent, followed by solvolysis to obtain a product mix. At least part of the product mix is recirculated as the oil fraction of said solvent. The present disclosure further concerns the use of the product mix as a renewable product or use of hydroprocessed oil obtained by the process.Type: GrantFiled: December 19, 2022Date of Patent: May 21, 2024Assignee: UPM-KYMMENE CORPORATIONInventors: Pekka Jokela, Andrea Gutierrez, Roel Westerhof, Sascha Kersten, Bert Heesink

Patent number: 11987759Abstract: The present disclosure relates to the thermal liquefaction of lignin, and more particularly to lignin solvolysis of a lignin feedstock chosen based on its molecular weight. The process comprises subjecting a feed mixture (30) of lignin feedstock (10) and solvent (20) to a thermal liquefaction step by heating (110) the feed mixture (30) at a temperature between 360 and 420° C., separating (120) a liquid product mix (50) from a product mix (40); and recirculating at least part of said liquid product mix (50) as an oil fraction of said solvent (20).Type: GrantFiled: December 19, 2022Date of Patent: May 21, 2024Assignee: UPM-KYMMENE CORPORATIONInventors: Andrea Gutierrez, Roel Westerhof, Sascha Kersten, Bert Heesink, Pekka Jokela

Publication number: 20230203381Abstract: The disclosure relates to a process for converting lignin (10) to renewable product (80), wherein the process comprises the following steps; mixing (100) lignin (10) with aqueous solution (20) to obtain a mixture (30); heating (110) the mixture (30) of step (a) to a temperature between 290 and 350° C., under a pressure from 70 to 165 bar, to obtain a first product mix (40); separating aqueous phase (53) and oil phase (50), and optionally gas (51) and solids (52), of the first product mix (40) of step (b); and heating (130) the oil phase (50) of step (c) and solvent (60) to obtain a second product mix (70). The second product mix (70) can be used as such, it can be directed to separation (140) or it can be upgraded. The obtained liquid renewable product is suitable as chemicals, fuel, fuel components or feedstock for fuel production.Type: ApplicationFiled: December 19, 2022Publication date: June 29, 2023Inventors: Andrea GUTIERREZ, Roel WESTERHOF, Sascha KERSTEN, Bert HEESINK, Pekka JOKELA

Patent number: 11634645Abstract: The present disclosure relates to a method for controlling product slate of hydrothermal liquefaction by adjusting pH of hydrothermal liquefaction product aqueous phase. The pH of the hydrothermal liquefaction product aqueous phase can be adjusted by heating during hydrothermal liquefaction (110) a mix (30) comprising lignocellulosic feedstock (10) together with acids, alkalis and/or buffers (20) added under aqueous conditions. The method typically comprises separating (120) aqueous phase (53) and oil phase (50), and optionally gas (51) and/or char (52), of the obtained hydrothermal liquefaction product (40). Preferably the separated aqueous phase (53) is recirculated to be mixed 100 with lignocellulosic feedstock (10).Type: GrantFiled: June 17, 2021Date of Patent: April 25, 2023Assignee: UPM-KYMMENE CORPORATIONInventors: Pekka Jokela, Andrea Gutierrez, Teemu Lindberg, Bert Heesink, Sascha Kersten, Roel Westerhof
