BOILING LIQUORS AND USE THEREOF Russian patent published in 2020 - IPC C10L1/00 C10G1/00 C10B49/00 C10B53/02 C12P7/08 D21C3/02 D21C3/24 

FIELD: chemistry.

SUBSTANCE: present invention relates to production of bioproducts based on organic matter, as well as to use boiling liquors during hydrothermal/thermochemical conversion of lignocellulose and/or fossil organic feedstock to biofuel (for example, bio-oil) and/or chemical products (for example, basic chemicals). Described is a method of producing a bio-oil product based on organic matter, involving: providing a reaction suspension mixture containing organic matter-based material, a solvent and black cooking liquor (black liquor), where black liquor was obtained independently from organic matter based raw material; treatment of reaction suspension mixture in reactor vessel at temperature from 300 to 400 °C and reaction pressure from 180 to 350 bar, as a result of which conversion of all or part of raw materials based on organic substance into a mixture of products containing a bio-oil product; and reducing pressure and cooling mixture of products; wherein during said treatment reaction slurry mixture and mixture of products move in continuous flow through vessel reactor. Also described is a bio-oil product which is obtained according to the method described above.

EFFECT: detection of suitable combinations of catalysts and/or alternative sources of catalysts enables to improve existing methods of producing bio-oil.
