  • Patent number: 12076712
    Abstract: Aqueous effluent treatment system including a separation reactor having a reactor chamber fluidly connected to an aqueous effluent source, connected via a pump to an inlet of the reactor chamber, a fluid extraction system connected to a liquid effluent outlet at a top of the reactor chamber, and a solid residue extraction system connected to a solid residue outlet at a bottom of the reactor chamber. The separation reactor is operable to generate pressures exceeding 22 MPa and temperatures exceeding 300° C. in the reactor chamber configured to generate a supercritical zone in an upper portion of the reactor chamber to which the liquid effluent outlet is connected, and a subcritical zone in a lower portion of the chamber within the reactor chamber to which the solid residue outlet is connected.
    Type: Grant

  • Patent number: 9637765
    Abstract: A process for pretreatment of a biomass material, comprising subjecting a biomass material to a biphasic mixture of water and supercritical CO2 at a temperature in the range of 150° C. to 250° C. under high pressure for a time of from 10 seconds to 100 minutes. In particular embodiments, the process is performed as a two-stage temperature process wherein an initial short high-temperature stage is conducted at a temperature of at least 200° C. for up to 20 minutes and a subsequent longer low-temperature stage is conducted at a temperature of at least 140° C. and up to 190° C. for 10-120 minutes.
