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 copper-containing additive; and (iii) at least a portion of the remainder of the copper-containing slag after separation of an enriched vanadium-containing coarse slag fraction. Materials (ii) and (iii) combine in the partial oxidation reaction zone with at least a portion of the nickel and iron constituents and the sulfur found in the feedstock to produce a liquid phase washing agent that collect and transports at least a portion of the vanadium-containing oxide laths and spinels and other ash components out of the reaction zone as molten vanadium-containing slag. A coarse slag fraction having a decreased Cu/V weight ratio is produced when a portion of the molten slag entrained in the hot raw effluent gas stream from the partial oxidation reaction zone is deposited on the walls of a slag sepa…
