  • Method and apparatus for tetrahydrocannabinol (THC) removal from hemp extracts via oxidation
    Patent number: 11987565
    Abstract: A method of oxidizing ?9-tetrahydrocannabinol (?9-THC) in hemp oil to cannabinol (CBN) uses a heated spray system assisted with ultraviolet (UV) lights. The method includes heating the hemp oil to keep the hemp oil flowing freely in the heated spray system. ?9-THC to CBN is converted by forming droplets in the presence of oxygen and the UV lights.

  • Combined liquid to solid-phase anaerobic digestion for biogas production from municipal and agricultural wastes
    Patent number: 8771980
    Abstract: Biogas is obtained in a solid-state anaerobic digester from a solid organic biomass and a digestion effluent produced in an associated liquid anaerobic digester. The solid organic biomass and digestion effluent are mixed to produce an effluent-biomass mixture. The effluent-biomass mixture is then incubated in the solid state anaerobic digester, producing a biogas and a digestate. The incubation is controlled by adjusting the composition and properties of the effluent-biomass mixture. The solid organic biomass may comprise lignocellulosic biomass, food waste, agricultural waste and the like.
