A partial oxidation process for the production of gaseous mixtures comprising H/sub 2/+CO is described comprising: (1) reacting the fuel feedstock in a free-flow reaction zone of a partial oxidation gas generator to produce a hot raw effluent gas stream at a temperature in the range of about 1800/sup 0/F to 3000/sup 0/F and a pressure in the range of about 5 to 200 atmospheres; (2) cooling the hot raw effluent gas stream from (1) to a temperature in the range of about 350/sup 0/F to 750/sup 0/F by direct or indirect heat exchange with water, and cleaning the raw effluent gas stream with water in a gas-liquid contacting zone to produce a clean synthesis gas stream saturated with water and containing a portion of at least one water soluble gaseous impurity (3) reacting a first portion of the cleaned stream of synthesis gas from (2) in admixture with the vaporized condensed water from (6) in a catalytic reaction zone, (4) cooling the stream of synthesis gas; (5) cooling the remainder of the cleaned stream of synthesis gas from (2) below the dew point; and separating condensed water containing at least one water soluble gaseous impurity; and (6) mixing and vaporizing at least a portion of the condensed water from (5) with the stream of synthesis gas passing into the catalytic reaction zone in (3).
