1. A system comprising:
a first reactor configured to generate a first product gas including char;
a solids separation device configured to separate the char from the first product gas to produce separated char and char-depleted product gas, wherein the char-depleted product gas has a reduced amount of char relative to the first product gas;
an eductor configured to accept a recycle gas and configured to entrain the separated char in a motive fluid that comprises the recycle gas; and
a second reactor configured to accept a mixture comprising the motive fluid with the separated char and configured to accept the char-depleted product gas, wherein the second reactor is further configured to react the separated char and the char-depleted product gas with an oxygen-containing gas to produce a final product gas.
