2048. LIEDHOLM, G. E., AND HARLAN, J. T. (Shell Development Co.). Production of Oxygenated Products From Petroleum. United States Patent 2,544,271, Mar. 6, 1951; appl. filed Jan. 13, 1947, Serial No. 721,736; 6 claims (Cl. 260-638). Chem. Abs., vol. 45, 1951, p. 4919.

Advantage of this method using 2-step Oxo process is that a synthesis gas made by the partial combustion of natural gas with O₂, which is already under pressure and does not have to be converted to a mixture containing prerequisite amounts of CO and H₂, may be employed. To use the gas in this manner, the synthesis gas is supplied directly to the 2d step of the synthesis, rather than to the 1^st, in an excess amount, and the excess gas, now containing the H₂ and CO in a suitable ratio, is passed to the 1^st synthesis step. 5 United States patents cited.
