NOVELTY - Producing fluid hydrocarbon products from solid hydrocarbonaceous material involves: feeding reactant comprising the material to reactor (25) by injection in gas jet; pyrolyzing a portion of the material; and catalytically reacting a portion of pyrolysis product. The gas jet comprising carrier fluid and the material enters the reactor through feed port (26). The material is fed through feed port into fluidization reactor with a ratio of gas flow rate through feed port to flow through a fluidization port of less than 10. The feed port has an angle of 15 degrees from horizontal.    USE - For producing fluid hydrocarbon product such as olefins, para- and meta-xylene, and methane, from solid hydrocarbonaceous material (claimed); and for producing biochemicals such as biofuel.    ADVANTAGE - The method provides carbon percent yield of aromatics plus olefins of at least 20%; carbon percent yield of para- and meta-xylene of at least 1.5%; and carbon percent yield of methane of less than 10%. The method minimizes premature heating of the biomass and mixes it rapidly with the materials in the reactor. The feed system for introducing biomass into pyrolysis reactor, such as a catalytic fast pyrolysis (CFP) fluid bed reactor, employs a jet stream of gas or vapor to inject the biomass particles into the fluid bed. 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. The method allows operation of the CFP process at higher pressure while allowing the feed to be maintained at lower pressures and injects the biomass in discrete portions that penetrate further into the reactor enhancing mixing and rapid heating of the biomass.    DETAILED DESCRIPTION - Producing at least one fluid hydrocarbon product from a solid hydrocarbonaceous material, involves: feeding a first reactant comprising solid hydrocarbonaceous material to a reactor (25) by injection in a gas jet; pyrolyzing within the reactor at least a portion of the hydrocarbonaceous material under reaction conditions to produce at least one pyrolysis product; and catalytically reacting at least a portion of the pyrolysis product under reaction conditions to produce the fluid hydrocarbon products. The gas jet comprises a carrier fluid and the solid hydrocarbonaceous material. The gas jet enters the reactor through a feed port (26), where the carrier fluid flows through the feed port with a linear velocity of at least 25 cm/sec. The solid hydrocarbonaceous material is fed through 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. The solid hydrocarbonaceous material is fed into the reactor through the feed port, where the feed port has an angle that is at least 15 degrees from the horizontal. INDEPENDENT CLAIMS are included for the following:    (1) a system for producing at least one fluid hydrocarbon product from a hydrocarbonaceous material comprising a pyrolysis zone; or a fluidized bed reactor comprising a lower section and an upper section; where the lower section comprises a gas mixture at 100-400 degrees C and suspended biomass solids, and the upper section comprises a suspension of catalyst particles and fully or partially pyrolyzed biomass, at at least 500 degrees C; and    (2) an apparatus for producing at least one fluid hydrocarbon product from a hydrocarbonaceous material, comprising in combination: a pyrolysis reaction chamber; at least one feed tube (12) by which solid hydrocarbonaceous material can be introduced by gas-assisted injection into the pyrolysis reaction chamber, where the angle alpha of the feed port is at least 15 degrees from the horizontal; a delivery structure by which a solid catalyst can be introduced; a fluidization gas inlet line connecting with a lower portion of the reaction chamber for introducing a fluidization gas (20); a catalyst exit conduit; and a product exit conduit from which vapor phase products can exit the reactor.
