✦ Synopsis

This paper provideq a method for facilitating the deslagging of a partial oxidation reactor used to produce syngas. The slag comprises vanadium trioxide and a siliceous material that accumulates on the interior walls of the partial oxidation reactor as a byproduct of the syngas production proces. Deslagging is achieved by controlled oxidation, here the vanadium to glass weight ratio is maintained equal or greater than 3:2. operating the reactor at a temperature of at least 2000"F, and maintaining controlled oxidation conditions sufficient to convert the vanadium trioxide in the slag to vanadium pentoxide.
