ABSTRACT:
The endothermic heat of reaction for zeolite-catalyzed paraffin aromatization is provided by a co-fed oxygenate stream. Advantageously, the addition of a dehydrogenation metal to the zeolite reduces the reaction temperature for paraffin aromatization to a range suitable for the exothermic conversion of an oxygenate to C.sub.5 + gasoline. Preferred paraffinic feedstreams include C.sub.3 -C.sub.4 LGP and the preferred oxygenate is methanol.
