Abstract: Disclosed is a method for making C2 or larger hydrocarbons from methane or for dehydrogenating C2 or larger hydrocarbons. The method can include contacting methane or C2 or larger hydrocarbons with a hydridable material under reaction conditions sufficient to effect removal of at least one hydrogen atom from a plurality of methane molecules or C2 or larger hydrocarbons to produce a plurality of methyl radicals or to dehydrogenate the C2 or larger hydrocarbons. With respect to the produced plurality of methyl radicals, they can combine together to form C2 or larger hydrocarbons. The reaction is performed in the absence of oxygen gas and reactive metal oxides.

Abstract: This invention is for a catalyst for conversion of alkanes having two to six carbon atoms per molecule to aromatics. The catalyst is a MFI zeolite with a crystallite size of less than 15 microns with, in addition to silicon and aluminum, germanium as a framework element. Platinum is deposited on the zeolite. The zeolite may contain other optional tetravalent and trivalent elements in the zeolite framework.

Abstract: This invention relates to a process for the aromatization of C6 to C12 alkanes, such as hexane, heptane and octane, to aromatics, such as benzene, ethyl benzene, toluene and xylenes, with a germanium-containing zeolite catalyst. The catalyst is a non-acidic aluminum-silicon-germanium zeolite on which a noble metal, such as platinum, has been deposited. The zeolite structure may be of MFI, BEA, MOR, LTL or MTT. The zeolite is made non-acidic by being base-exchanged with an alkali metal or alkaline earth metal, such as cesium, potassium, sodium, rubidium, barium, calcium, magnesium and mixtures thereof, to reduce acidity. The catalyst is sulfur tolerant and may be pretreated with a sulfur compound, i.e., sulfided. The hydrocarbon feed may contain sulfur up to 1000 ppm. The present invention could be applicable to a feedstream which is predominantly paraffinic and/or low in naphthenes. Lowering the hydrogen to hydrocarbon ratio increases conversion and aromatics selectivity.

Abstract: This invention relates to a process for regeneration of a zeolite catalyst, specifically an aluminosilicate zeolite with germanium substituted in the framework for silicon and with platinum deposited on the zeolite. The catalyst may be used in a process for aromatization of alkanes, specifically C2-C8 alkanes. The regeneration process 1) removes coke and sulfur from the catalyst via oxidation, 2) redisperses platinum on the surface of the catalyst via chlorine gas, 3) removes chlorine and bind Pt to the surface of the zeolite by steaming, 4) reduces the catalyst in hydrogen, and 5) optionally, resulfides the catalyst. The zeolite may be a MFI zeolite. The catalyst may be bound with an inert material which does not act as a binding site for platinum during the regeneration process, for example, silica.

Abstract: This invention relates to a process for making a germanium-zeolite without using fluoride compounds. The zeolite is preferably a MFI-type structure, most preferably a ZSM-5 MFI zeolite. The germanium-zeolite is synthesized essentially in the absence of fluoride compounds from an aqueous gel containing a silica source, a germanium source, an aluminum source and a structure directing agent in the presence of an acid which does not contain fluorine, such as sulfuric acid, acetic acid, nitric acid, phosphoric acid hydrochloric acid or formic acid.
