INTEGRATED KRAFT PULP MILL AND THERMOCHEMICAL CONVERSION SYSTEM

This disclosure pertains to the use of black liquors from kraft pulp mills as a source of catalysts for the thermochemical conversion of organic matter feedstocks to bio oils. More particularly, some embodiments pertain to integrated kraft pulp mill and thermochemical conversion systems, which include: a Kraft pulp mill comprising a digester for digesting a lignocellulosic material with white liquor to produce pulp and black liquors; a thermochemical conversion subsystem comprising: at least one mixing tank for combining pulping liquors received from the pulp mill with an organic matter feedstock and water to produce a reaction mixture; a reactor vessel for treating the reaction mixture received from the mixing tank at a reaction temperature and pressure suitable for conversion of all or a portion of the organic matter in the reaction mixture into a product mixture comprising a bioproduct and an aqueous stream containing both organic and inorganic compounds; and a depressurizer for depressurizing product mixture received from the reactor vessel; and one or more conveyors for conveying the pulping liquors from the pulp mill to the mixing tank.

Multi-step process for the isolation of components from <i>Miscanthus</i>
11814790 · 2023-11-14 · ·

The invention relates to a process for the isolation of components from plant material of Miscanthus. The process comprises three subsequent extractions. The first extraction yields an extract comprising one or more compounds selected from the group of antioxidants, polyphenols, proteins, sterols, acids, alcohols, ketones, aldehydes and aromatic compounds. Thereafter, the plant material is subjected to two extractions with a metal hydroxide (e.g. NaOH), the first performed at a lower pH than the second. These steps yield a sugar fraction and a Iignin fraction, respectively. Finally, from the residue after the third extraction, cellulose is isolated.
