Abstract: A method for the aromatization of hydrocarbons, comprising: introducing a feed stream to an aromatization catalyst in a fixed bed reactor wherein the feed stream comprises a hydrocarbon having 2 to 4 carbon atoms, converting the hydrocarbon having 2 to 4 carbon atoms to form an outlet stream comprising an aromatic hydrocarbon; wherein the feed stream is introduced at a GHSV of greater than or equal to 4,000 milliliters per gram of catalyst per hour (ml·g−1 Cat·h−1), and a pressure of greater than or equal to 0.4 MPa. The feed stream can comprise hydrogen in an amount of at least 0.1 volume percent (vol %) up to 20 vol % based upon total volume of the feed stream.
