INCORPORATED SYSTEM OF KRAFT-PULP PLANT AND THERMOCHEMICAL TRANSFORMATION Russian patent published in 2019 - IPC D21C11/00 

FIELD: chemistry.

SUBSTANCE: invention relates to use of black liquors from kraft-pulp plants as a source of catalysts for thermochemical conversion of organic matter-based material to biomass. More specifically, some versions of implementation relate to combined system kraft-pulp plant and thermochemical conversion, which includes: kraft-pulp plant containing cooking apparatus for digestion of lignocellulose material with white liquor to produce cellulose pulp and black liquors; thermochemical transformation subsystem comprises: at least one mixing tank for combining cooking liquors, obtained from a pulp plant, with raw material based on organic substance and water to obtain a reaction mixture; reactor vessel for processing a reaction mixture obtained from a mixing tank at a reaction temperature and pressure suitable for converting all or part of the organic substance in the reaction mixture into a mixture of products containing a bioproduct and an aqueous stream containing both organic and inorganic compounds; and a device for reducing pressure for reducing pressure of a mixture of products obtained from a reactor vessel; and one or more conveyors for transporting cooking liquors from pulp plant to mixing tank.

EFFECT: disclosed is kraft-pulp plant combined system and thermochemical transformation.
