GAS JET INJECTOR REACTOR FOR CATALYTIC FAST PYROLYSIS PROCESS

摘要

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.

1. A method for producing one or more fluid hydrocarbon products from a solid hydrocarbonaceous material comprising:
feeding a first reactant comprising the solid hydrocarbonaceous material to a reactor by injection in a gas jet; pyrolyzing within the reactor at least a portion of the hydrocarbonaceous material under reaction conditions sufficient to produce one or more pyrolysis products; and catalytically reacting at least a portion of the one or more pyrolysis products under reaction conditions sufficient to produce the one or more fluid hydrocarbon products; and further comprising one or more of the following characteristics: wherein the gas jet comprises a carrier fluid and the solid hydrocarbonaceous material, wherein the gas jet enters the reactor through a feed port and wherein the carrier fluid flows through the feed port with a linear velocity of at least 25 cm/sec; or wherein the solid hydrocarbonaceous material is fed though a feed port into a fluidization reactor with a ratio of gas flow rate through the feed port to flow through a fluidization port of less than 10; or wherein the solid hydrocarbonaceous material is fed into the reactor through a feed port wherein the feed port has an angle that is at least 15 degrees from the horizontal.
