    Abstract: A two-stage syngas production method to produce a final product gas from a carbonaceous material includes producing a first product gas in a first reactor, separating char from the first product gas to produce separated char and char-depleted product gas, and separately reacting the separated char and the char-depleted product gas with an oxygen-containing gas in a second reactor to produce a final product gas. The separated char is introduced into the second reactor above the char-depleted product gas. The solids separation device may include serially connected cyclones, and the separated char may be entrained in a motive fluid in an eductor to produce a char and motive fluid mixture prior to being transferred to the second reactor. A biorefinery method produces a purified product from the final product gas.
