Abstract: Alkanes, preferably lower alkanes, are converted to olefins in a `third bed` external catalyst cooler (ECC) in which hot catalyst from a first regenerator (`second bed`) operating in conjunction with a fluid catalytic cracker (`first bed`) thermally cracks and dehydrogenates the alkanes. Because this is an endothermic reaction, the catalyst is autogeneously cooled before it is recirculated to the FCC regenerator. The cracking catalyst is the catalyst of choice in the FCC reactor. The conversion of alkanes to olefins is tailored to provide a mixed feed for an aromatization reactor (`fourth bed`) which feed is proportioned to provide a substantially heat-balanced reaction in the aromatization reactor, that is, requiring no additional heat other than that which is provided by the feed and the heat of reaction. A second regenerator (`fifth bed`) is provided for the aromatization reactor, preferably in a moving bed reactor system. This reactor produces a predominately aromatic hydrocarbon stream.

Abstract: Steam active reforming catalyst is described which in addition to converting isoparaffins to isoolefins also isomerizes 1-olefins at least in part to internal olefins. In a combined steam active reforming and ether forming operation a 1-olefin containing stream can be recycled to the steam active reforming zone whereby this 1-olefin is converted to materials which in a separation step downstream from the ether forming reaction can be readily separated from the isoparaffin, the isolefin and the 1-olefin which are recycled to the steam active reforming zone. The steam active reforming catalyst thus has both the function of a reforming (dehydrogenation) catalyst and that of an isomerization catalyst for disposing of the 1-olefin byproduct and preventing its buildup in the operation.
