In a partial oxidation process for the production of gaseous mixtures comprising H/sub 2/ + CO in the reaction zone of a down flowing gas generator, this patent describes the improvement comprising: (1) mixing together the following materials to produce a feed mixture, (i) a vanadium-containing fuel; (ii) supplemental iron-containing ash fusion temperature reducing agent containing iron compounds; and (iii) at least a portion of the remainder of the iron-containing slag after separation of the course slag fraction; (2) reacting by partial oxidation the feed mixture with a free-oxygen containing gas in the presence of a temperature moderator in a refractory-lined free-flow unpacked reaction zone of the gas generator the vanadium-containing feed mixture from (1) to produce a hot raw effluent gas stream comprising H/sub 2/ + CO along with vanadium-containing molten slag and particulate matter; (3) passing the hot raw effluent gas stream from (2) at a temperature in the range of about 2200/sup 0/F to 3000/sup 0/F and a pressure in the range of about 1 to 300 atmospheres down through a coaxial discharge passage in the bottom of the reaction zone of the gas generator; (4) passing through the hot effluent gas stream; and (5) passing the water and solids from the bottom of the quench tank into a water-solids separation zone.
