摘要: Partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide is carried out by a fixed bed or a fluidized bed process which includes the steps of passing steam and/or carbon dioxide 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 producing hydrogen and/or carbon monoxide, 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 and carbon monoxide.
