Partial oxidation of vanadium-containing heavy liquid hydrocarbonaceous and solid carbonaceous fuels
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, the improvements are described comprising: (1) mixing together the following materials to produce a feed mixture (i) a vanadium-containing fuel whose ash includes a minimum of 2.0 weight % of vanadium selected from the group consisting of liquid hydrocarbonaceous fuel, a slurry of solid carbonaceous fuel, and mixtures thereof; (ii) supplemental copper-containing additive; and (iii) at least a portion of the remainder of the copper-containing slag after separation of the coarse slag fraction in (5); (2) reacting by partial oxidation in a refractory-lined free-flow unpacked reaction zone of the gas generator the vanadium-containing feed mixture from (1) with a free-oxygen containing gas in the presence of a temperature moderator and in a reducing atmosphere to produce a hot raw effluent gas stream comprising H/sub 2/+CO along with vanadium-containing molten slag comprising a liquid phase washing agent that collects and transports vanadium-containing laths and spinels and other ash components and refractory out of the reaction zone; (3) passing the hot raw effluent gas stream down through a coaxial discharge passage in the bottom of the reaction zone of the gas generator; (4) passing through the quench tank at least a portion of the hot effluent gas stream leaving the slag separation chamber to produce the gaseous mixture comprising H/sub 2/+CO, and solidifying molten slag; and (5) passing the water and solids from the bottom of the quench tank into a water-solids separation zone.
