Abstract
Process for the production of gaseous mixtures comprising H.sub.2 +CO e.g. synthesis gas, reducing gas, or fuel gas by the partial oxidation of a vanadium-containing liquid hydrocarbonaceous fuel, solid carbonaceous fuel, or mixtures thereof in a free-flow vertical refractory lined gas generator. The feed mixture to the gas generator comprises (i) a vanadium-containing fuel; (ii) supplemental iron-containing ash fusion temperature reducing agent; and (iii) at least a portion of the remainder of the iron-containing slag after separation of an enriched vanadium-containing coarse slag fraction. The coarse slag fraction has a decreased Fe/V weight ratio and is formed by depositing a portion of the slag entrained in the hot raw effluent gas stream from the partial oxidation reaction zone on the walls of a slag separation chamber located between the bottom discharge outlet in the reaction zone and the effluent gas quench tank located at the bottom of the gas generator. It is economically advantageous to recover by-product vanadium from the coarse slag fraction in a metal refining plant.
