ABSTRACT:
Synthesis gas is produced by the partial oxidation of a feedstock comprising petroleum coke and/or heavy liquid hydrocarbonaceous fuel containing sulfur and having an ash that contains nickel, vanadium and a comparatively high level of silicon. An iron and calcium-containing additive is introduced into the reaction zone along wth the feed. Separate portions of the additive (i) combine with a portion of the nickel, calcium and sulfur to generate a liquid phase washing agent that collects and transports out of the gas generator a portion of the vanadium-containing oxide laths and spinels and other ash components; and (ii) combine with a portion of the nickel, calcium and silicon to generate a liquid oxide-silicate phase that fluxes e.g. dissolves substantially all of the remaining portion of said vanadium-containing oxide laths and spinels and other ash components. In another embodiment, a minor amount of an additonal material selected from the group of elements consisting of magnesium, chromium, manganese, and mixtures thereof is included in the iron and calcium-containing additive. In still another embodiment, the iron and calcium-containing additive is uniformly dispersed in petroleum coke having a nickel and vanadium-containing ash. By this method two types of molten slag having reduced viscosities and containing the nickel and vanadium-containing impurities from the feedstock are readily removed from the gas generator at a lower temperature. Further, the life of the refractory lining is extended.
