Patent ID: 7547419

Claim:
A high-velocity, rocket-style impinging injector for injecting reactants into the bed of a two-particle, fluidized-bed reactor of a type used for the production of hydrogen from methane by a steam reforming process, said injector comprising: a plate disposed horizontally within the reactor and below the fluidized bed thereof, the plate having: a central orifice extending substantially perpendicularly through the plate; a peripheral orifice disposed adjacent to the central orifice and extending through the plate at a transverse angle relative to the central orifice such that a stream of reactants injected into the reactor bed through the peripheral orifice impinges on a stream of reactants injected into the reactor bed through the central orifice; and a plurality of base-bleed orifices disposed around the injector and extending substantially perpendicularly therethrough, wherein the peripheral orifice is located closer to the central orifice than each of the base-bleed orifices.
