2091. LYNCH, C. S. (Standard Oil Development Co.). Re-forming Hydrocarbon Gases in the Presence of a Magnesia Catalyst. United States Patent 2,593,584, Apr. 22, 1952; appl. filed Dec. 1, 1948, Serial No. 62,838; 11 claims (Cl. 252-373).

Synthesis gas mixtures containing H₂ and CO in a ratio < 3:1 are prepared by passing a hydrocarbon gas, consisting essentially of CH₄, with an oxidizing gas containing a major proportion of CO₂ and a minor proportion of steam, 1^st over a catalyst consisting of MgO at a conversion temperature 1,400°-1,800° F., and then over a 2d catalyst comprising an Fe-group metal at 1,200°-1,500° F. No C formation on the catalyst occurs in this conversion.
