Abstract: A catalyst for converting ethane to monoaromatic hydrocarbons including: a zeolite; cesium oxide, wherein cesium of the cesium oxide is present in an amount of 0.01 to 0.5 weight percent, preferably 0.01 to 0.1 weight percent, more preferably 0.03 to 0.07 weight percent, based on a total weight of the catalyst; platinum oxide, wherein platinum of the platinum oxide is present in an amount of 0.01 to 1 weight percent, preferably 0.01 to 0.5 weight percent, more preferably 0.01 to 0.05 weight percent, based on a total weight of the catalyst; and gallium oxide, wherein gallium of the gallium oxide is present in an amount of 0.01 to 1 weight percent, preferably 0.03 to 0.5 weight percent, more preferably 0.05 to 0.2 weight percent, based on a total weight of the catalyst; wherein the monoaromatic hydrocarbons include benzene, toluene, xylene, or a combination including at least one of the foregoing.

Abstract: Methods for producing propylene by the dehydrogenation of propane are provided. Methods can include introducing a first gas mixture including propane to a dehydrogenation catalyst at a temperature of at least about 570° C., introducing a second gas mixture including steam and air to the dehydrogenation catalyst at a temperature of at least about 550° C., and allowing the second gas mixture to subsist therewith for at least about one hour. Methods can further include introducing a third gas mixture including hydrogen to the dehydrogenation catalyst at a temperature of at least about 500° C.
