Abstract
A method for producing char and fuel gas includes degasifying a carbonaceous material with oxygen-containing gases in a fluidized bed reactor at a temperature of more than about 1000° C. and at a pressure of from about 1 bar to about 40 bar. A supply of oxygen within the fluidized bed reactor is adjusted so as to recover more than 60% of fixed carbon in the carbonaceous material in a char product, and an oxygen availability in a lower or bottom region of the fluidized bed reactor is less than 80% of an oxygen availability in an upper region of the fluidized bed reactor.
