3722.  SWEETSER, S.B., AND SCHARMANN, W.G. (Standard Oil Development Co.).  Process for Water-Gas Generation.  United States Patent 2,652,319, Sept. 15, 1953; appl. filed Jan. 3, 1949, Serial No. 68,946; 8 claims (Cl. 48-206).

Claim 1.  The process of producing gas mixtures containing CO and H₂ comprises passing a stream of finely divided carbonaceous solid material into an initial water-gas reaction zone, forming a fluidized mass of solids therein, subjecting said mass to a gasification reaction with steam at temperatures of 1,500°-2,000° F. to produce a gas rich in H₂ and CO, withdrawing said gas from said water-gas reaction zone. Withdrawing finely divided char of high surface area from said water-gas reaction zone, passing at least a portion of said char into a catalyst impregnating in said zone said char with a catalyst promoting gasification of C, recycling said impregnated char of high surface area to said water-gas reaction zone, and recovering a gas rich in H₂ and CO from said last-named zone.
