      1.  ABRAMS, A. J., GORIN, M. H., and BAKER, C. O. (Secony-Vacuum Oil Co., Inc.).  Carbon Monoxide and Hydrogen From Methane.  United States Patent 2,449,359, Sept. 14, 1948: appl filed Jan. 25, 1945, Serial No. 574,612: 15 claims (Cl. 48-196). Chem. Abs. Vol. 42, 1948, p. 9124.

CH, or natural gas is cracked to yield H₂ and C by passage up through a tower filled with refractory, such as CaO, heated by a countercurrent stream of melted Sn or Ph entering at around 2,150° F. (range 1,800°-2,400° F.).  Part of the C deposited on the refractory is removed by reaction with CO₂ recovered in the process, and the rest of the C is removed by oxidation with air to form a producer gas, which is burned to supply part of the heat requirements for heating the molten metal.  The combustion products from the metal heating furnace are passed over CaO to absorb CO₂: this CO₂ is later desorbed by the hot metal from the reaction tower and the cooled but still fluid metal is then pumped to the heating furnace, where it is protected from oxidation during heating by a layer of Cataphosphate.  The desorbed CO₂ is used as described above.  The process is carried out in such a manner as to give a mixture of CO and H₂ 1:2.
