Vanadium addition to petroleum coke slurries to facilitate deslagging for controlled oxidation

摘要

A method facilitating the deslagging of a partial oxidation reactor used to produce syngas is disclosed. The slag comprises vanadium trioxide and a siliceous material that accumulate on the interior walls of the partial oxidation reactor as a byproduct of the syngas production. The deslagging is accomplished by controlled oxidation, wherein the vanadium to glass weight ratio is maintained to at least about 3:2, operating the reactor at a temperature of at least about 2000° F, and maintaining controlled oxidation conditions sufficient to convert the vanadium trioxide in the slag to vanadium pentoxide.
