1742.         1742. JACOLEV, L., AND GERMAN, I. F. (The Texas Co.).  Preparation of Synthesis Gas.  United States Patent 2,591,700.  Apr. 8, 1952: appl. filed May 28, 1948, Serial No. 29,866: 8 claims (Cl. 48-196).

Methods contemplates the reaction of CH₄ and O₂ in the proportion of about 1:1 in an enclosed, unobstructed reaction zone, the incoming stream of reactants being passed longitudinally through the central portion of the reaction zone at about 2,000° and 200 p. s. i., the direction then being reversed and directed into a spirally moving flow surrounding the central stream of incoming gases.  In this way the 2 streams flow in countercurrent heat-exchange relationship whereby the reaction is materially promoted and maximum yields of CO and H₂ are realized.  Also, the overall reaction is carried out in a relatively limited reaction space, which contributes materially to economy of size and investment required for large-scale operation.
