ABSTRACT:
Synthesis gas is produced by the partial oxidation of a fuel feedstock comprising a heavy liquid and/or petroleum coke having a sulfur, nickel and vanadium-containing ash. An additive comprising basalt is introduced into the reaction zone along with the feed. The basalt additive interacts with the ash and sulfur in the feedstock to produce molten slag comprising a minor amount of oxysulfide liquid phase washing agent and a major amount of liquid silicate phase. The minor oxysulfide liquid phase washing agent collects and transports at least a portion of the vanadium-containing oxide laths and spinels and other ash components out of the reaction zone. The remainder of the vanadium is washed or dissolved by the major silicate phase. In another embodiment, the basalt additive is uniformly dispersed in petroleum coke having a sulfur, nickel and vanadium-containing ash. By this method molten slag having a reduced viscosity and containing the nickel and vandium-containing impurities from the feedstock and a large proportion of the sulfur from the fuel feedstock is readily removed from the partial oxidation gas generator at a lower temperature. Further, the life of the refractory lining of the partial oxidation gas generator is extended.
