            In obtaining synthesis gas from hydrocarbons by their incomplete combustion with air or O₂, if desired in the presence of steam and solid catalysts, a catalyst in vapor form is used consisting of a saturated vapor of a metal of the Fe group.  Example: 176 m.3 of a S-containing manufactured gas were reacted with 40 m.3 of O₂ and steam in a reactor filled with a Ni-Mg catalyst.  At the entrance to the reactor were added per hr. 4 gm. Fe in the form of Fe carbonyl.  At a temperature of 990º at the outlet of the reactor, a gas mixture was obtained composed essentially of CO+H₂ with only 0.25% of CH₄.  There was not stoppage owing to C deposition with these quantities of Fe, O₂, and steam.
