Abstract: 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).

Abstract: The disclosure relates to thermal liquefaction, typically solvolysis of lignin feedstocks originating from an integrated kraft pulp mill, where side stream(s) of the thermal liquefaction is directed to the kraft pulp mill of the integrated process, especially to the recovery boiler of the kraft pulp mill. More in detail the disclosure relates to a process for; converting lignin to renewable liquid product(s) in a thermal treatment process; separating a fraction having a boiling point over 500° C. at atmospheric pressure; and recycling at least part of the fraction having a boiling point over 500° C. at atmospheric pressure to the recovery boiler and/or lime kiln of the kraft pulp mill. The present disclosure further concerns the use of the integrated process for controlling the incineration capacity of the recovery boiler and use of steam and/or electricity from the recovery boiler for heating in the thermal liquefaction step.

Abstract: 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.
