  • Fluidized bed reactor systems and methods for torrefaction and catalytic pyrolysis of biomass
    Patent number: 12285751
    Abstract: A fluidized bed reactor for biomass treatment comprising a vessel extending in a first direction from a first end to a second end, an inlet at the first end of the vessel for feeding biomass particles into the vessel, an outlet at the second end of the vessel for outputting processed biomass, a first fluid inlet independently activatable to deliver a first volume of a gas in a second direction into a first region of the vessel, and a second fluid inlet spaced apart from the first fluid inlet in the first direction and independently activatable to deliver a second volume of the gas in the second direction into a second region of the vessel, the second region adjacent the first region.
