777. ------. [GARRISON, A. D.] (Texaco Development Corp.) Process for Preparing Synthesis Gases. United States Patent 2,566,936, Sept. 4. 1951: appl. filed Jan. 4, 1947, Serial No. 720,272: 3 claims (Cl. 252-373).

Synthesis gas composed essentially of H₂ and CO in the ratio 2:1 is produced from a hydrocarbon gas, such as natural gas and steam, by passing the same over a refractory material, heated previously to about 3,600º F. by the combustion of tail gas from a previous operation, air, steam, and CH₄, whereby it is cracked to gases and C and the latter deposited upon the refractory material. Cracking is continued until the temperature of the refractory is reduced to 3,000º-3,400º F. When the cracked gases are withdrawn, a mixture of steam and hydrocarbon gas is passed over the C on the refractory material at 1,800º-3,000º F. thereby effecting reaction of steam with the C and the hydrocarbon gas with production of H₂ and CO in the molar ratio desired.
