2750. REED, F. C. Carbon Black and Carbon Monoxide-Hydrogen Gas Mixtures From Natural Gas, etc. United States Patent 2,173,695, Sept. 19, 1939; appl. filed July 9, 1934, Serial No. 734,435; 8 claims (Cl. 23-212). Chem. Abs., vol. 34, 1940, p. 597.

Describes arrangement of apparatus and a process that comprises alternating the periods of combustion and dissociation of hydrocarbons within closed retorts, separating CO2 from the gases of combustion, subjecting hydrocarbons to dissociating temperatures during said dissociating periods for producing a gas mixture of CH4 and H2, utilizing said CO2 to cool the products of dissociation by heat exchange therewith, catalyzing any unsaturated compounds present to CH4, then adding said CO2 to said CH4 and H2 and subjecting the resultant mixture to high temperatures to produce said CO2-H2 gas mixtures.
