<p>Synthesis gas is produced by the partial oxidation of a feedstock comprising petroleum coke and/or heavy liquid hydrocarbonaceous fuel and/or solid carbonaceous fuels containing sulfur and having an ash that contains nickel, vanadium and silicon. An iron-containing additive is introduced into the reaction zone along with the feed. A first portion of the additive combines with at least a portion of the nickel, iron and sulfur constituents found in the feedstock to produce a first liquid phase washing agent. A second portion of the additive combines with at least a portion of the silicon, aluminum, calcium, sodium, and/or potassium and iron constituents found in the feedstock to produce a second liquid phase washing agent. The first and second liquid phase washing agents collect and transport at least a portion of the vanadium-containing oxide laths and spinels and other ash components out of the reaction zone.</p> |
