Abstract

The present invention provides a method which includes loading a zeolite catalyst in ammonium form with palladium ions, drying and calcining the palladium ion-laden zeolite catalyst to a proton form, fractionating the proton form of the palladium ion-laden zeolite catalyst into a powder, mixing the powder with an inert material, introducing the mixture into a fixed bed reactor, heating the fixed bed reactor to a reaction temperature and passing an inert gas therethrough, reducing the mixture in a hydrogen stream, passing an inert gas through the fixed bed reactor, introducing a reactant gas feed of hydrogen, an inert gas and dimethyl ether or methanol into the fixed bed reactor to form a product gas mixture, condensing the product gas mixture to a product phase liquid, and separating the product phase liquid into an aqueous and into an organic phase which includes the low-aromatics C₅₊ hydrocarbons.
