ABSTRACT:
Partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide is carried out by a fluidized bed process which includes the steps of passing air through a perovskite-type ceramic mixed conductor in an adsorption zone at an elevated temperature, thereby at least partially saturating the mixed conductor with oxygen, and subsequently contacting the hot, at least partially oxygen-saturated mixed conductor with a hydrocarbon in a partial oxidation reaction zone. During the partial oxidation reaction phase of the process, the sorbed oxygen reacts with the hydrocarbon, thereby producing hydrogen, carbon monoxide or mixtures of these. The oxygen-depleted mixed conductor is recycled to the adsorption zone.
