OSTI ID:6742015

This patent describes a continuous method of producing carbon monoxide and hydrogen from a solid carbonaceous material by introducing said powder to a vertical combustion zone and introducing to the lower portion of said zone a stream of oxygen-containing gas. The gas is passed upwardly through the combustion zone in contact with said powder so that the powder is maintained dispersed in gas within said zone. A stream of hot combustion gas is discharged from the upper zone separating entrained hot carbonaceous particles from said discharged gas and ash. The residual hot-gas stream is passed in indirect contact with a stream of steam, injected with said separated hot particles, and the resulting hot mixture of steam and injected particles being passed upwardly through a vertical reaction zone. An effluent steam of carbon monoxide and hydrogen containing entrained particles of unconsumed carbonaceous material and ash is removed from the upper reaction zone. This stream is separately entrained, with unconsumed carbonaceous material from said carbon monoxide, hydrogen, and ash, being recycled to said combustion zone. Ash from said effluent stream of gas is separated so as to provide a gaseous mixture comprising mainly carbon monoxide and hydrogen.
