3334. SÉPULCHRE, F. [Synthesis Gas.]  French Patent 915,433, Nov. 6, 1946; appl. filed May 23, 1945.  Chem. Zentralb., 1949, No. 2, p. E 145.

To simplify the production of synthesis gas for catalytic gas synthesis through the gasification of fuel, the conversion of CO, and decomposition of hydrocarbons, the conversion of the undesirable gas constituents is carried out directly in the gas producer at very high temperatures of about 1,500°-1,800°.  By this method the conversion of the undesirable constituents is carried out, not by H₂O vapor, but by hydrocarbons or their oxygenated compounds, since the cracking of the H₂ in these requires less energy than does the cracking of steam.  To avoid cooling the gas between the injection of the hydrocarbon and the gas-collection points, a special arrangement for directly combining both steps and mutually regulating them is described.
