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 6):
A system for processing a carbonaceous feedstock to create product gas, comprising:\n (a) a first reactor ( 500 ) having a fluidized bed ( 510 ) and configured to receive a feedstock ( 590 ) and superheated steam, and output a syngas stream ( 600 ) via a first conduit ( 602 ), the syngas stream ( 600 ) comprising syngas, char, condensable organic compounds and aromatic hydrocarbons, the fluidized bed ( 510 ) within the first reactor ( 500 ) being indirectly heated by a plurality of heating conduits ( 570 ), the heating conduits ( 570 ) comprising pulse heater tailpipes and/or electrical heater rods; and (b) a second reactor ( 100 ) in accordance with the reactor of  claim 1 , wherein: the nozzle ( 440 ) of the second reactor ( 400 ) is in fluid communication with the first conduit ( 602 ), and char produced by the first reactor ( 500 ) is introduced through the nozzle ( 440 ) as the solid carbon containing substance, the second reactor ( 100 ) is configured to operate under conditions sufficient to convert the char into a second-stage product gas stream ( 910 ).
