- (a) a first reactor (100) having a first interior (101) and comprising;
a first reactor carbonaceous material input (104) to the first interior (101);
a first reactor reactant input (108) to the first interior (101), anda first reactor product gas output (124);
(b) a second reactor (200) having a second interior (201) and comprising;
a second reactor char input (204) to the second interior (201), in fluid communication with the first reactor product gas output (124);
a second reactor oxygen-containing gas input (220) to the second interior (201);
a second reactor product gas output (224); and
a second reactor heat exchanger (HX-B) in thermal contact with the second interior (201), the second reactor heat exchanger comprising a second reactor heat transfer medium inlet (212) and a second reactor heat transfer medium outlet (216), the second reactor heat transfer medium outlet (216) being in fluid communication with the first reactor reactant input (108); and
(c) a third reactor (300) having a third interior (301) and comprising;
one or more product gas inputs (303, 304, 305) to the third interior (301), in fluid communication with the first and second product gas outputs (124, 224);
a third reactor oxygen-containing gas input (320) to the third interior (301);
a third reactor product gas output (336); and
a third reactor heat exchanger (HX-C) in thermal contact with the third interior (301), the third reactor heat exchanger comprising a third reactor heat transfer medium inlet (312) and a third reactor heat transfer medium outlet (316), the third heat transfer medium outlet (316) being in fluid communication with the second reactor heat transfer medium inlet (212);
wherein;
the third reactor heat exchanger (HX-C) is configured to receive a heat transfer medium (310) at a third reactor inlet temperature (T0) via the third reactor heat transfer medium inlet (312); and
a first portion of the heat transfer medium (310) passes through the third reactor heat exchanger (HX-C) and then the second reactor heat exchanger (HX-B) before being introduced, into the first interior (101) via the first reactor reactant input (108), as a reactant (100) at a first reactor reactant temperature (TR1), the first reactor reactant temperature (TR1) being higher than the third reactor inlet temperature (T0).

Abstract
A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.
