GAS JET INJECTOR REACTOR AND METHOD FOR CATALYTIC FAST PYROLYSIS

Methods and Systems utilizing gas jets to carry biomass into a biomass conversion reactor are described. Reactor configurations and conditions for carrying out processes utilizing the gas jets are also described. The use of gas jets has been found to be especially desirable for operation with pyrolysis of biomass in catalytic fluidized bed reactors. A feed system for introducing biomass into a pyrolysis reactor, such as a catalytic fast pyrolysis (CFP) fluid bed reactor, that employs a jet stream of gas or vapor to inject the biomass particles into the fluid bed is disclosed. The biomass is kept relatively cool, can be metered upstream of a gas jet, and can be injected far into the fluid bed. Good mixing between the relatively cooler biomass with the hot catalyst and other materials in the fluid bed can be insured by adjustment of the number, size, angle, Position, and flow rate of the multiple injector ports in larger reactors.
