Abstract:
A solids circulation system receives a gas stream containing char or other reacting solids from a first reactor. The solids circulation system includes a cyclone configured to receive the gas stream from the first reactor, a dipleg from the cyclone to a second reactor, and a riser from the second reactor which merges with the gas stream received by the cyclone. The second reactor has a dense fluid bed and converts the received materials to gaseous products. A conveying fluid transports a portion of the bed media from the second reactor through the riser to mix with the gas stream prior to cyclone entry. The bed media helps manipulate the solids that is received by the cyclone to facilitate flow of solids down the dipleg into the second reactor. The second reactor provides additional residence time, mixing and gas-solid contact for efficient conversion of char or reacting solids.

Claim (Index 1):
A reactor ( 100 ) for producing carbon monoxide, carbon dioxide, and hydrogen from a solid carbon-containing substance, comprising:\n (a) a fluidized bed comprising bed material in the form of hollow engineered particles selected from the group consisting of alumina, zirconia, sand, olivine sand, limestone, dolomite and metal catalyst; (b) a freeboard ( 160 ) located above a bed level of the fluidized bed; (c) a cyclone ( 700 ) positioned within the freeboard ( 160 ) of the reactor ( 100 ), the cyclone ( 700 ) configured to capture and recycle entrained bed material and char particles to the fluidized bed; (d) a plurality of fluid addition stages located in the freeboard ( 160 ), the plurality of fluid addition stages configured to introduce a mixture of oxygen and superheated steam to the freeboard ( 160 ) to promote conversion of char into CO, CO 2 , and H 2 ; (e) a distributor ( 140 ) configured to accept and distribute a fluidization media ( 130 ) comprising oxygen and superheated steam into the bed material of the fluidized bed; (f) at least one heating conduit ( 170 ) that protrudes into the bed material within the reactor ( 100 ) to heat the fluidized bed; and (g) a nozzle ( 440 ) configured to input a solid carbon-containing substance into the fluidized bed, for reacting with the oxygen and superheated steam to produce CO, CO 2 , and H 2 .
