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: Aromatization of alkanes having one to four carbon atoms per molecule to aromatics, such as benzene, toluene and xylenes (BTX), uses a catalyst of a crystalline zeolite on which platinum has been deposited, specifically a platinum-containing ZSM-5. A byproduct of the process is a light gas fraction of methane and ethane. The use of a platinum-containing ZSM-5 catalyst in an alkane aromatization process, such as the Cyclar process, suppresses the formation of methane and increases selectivity to BTX. The high content of ethane relative to methane in the light gas fraction allows this process effluent to be a feedstream for a cracker.

Abstract: This invention relates to a process for making a germanium-zeolite. The zeolite is preferably a MFI-type structure, most preferably a ZSM-5 MFI zeolite. The germanium-zeolite is synthesized 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 to control the pH of the gel in the range of 6.5 to 13.5, preferably 7.5 to 11, to maximize the amount of germanium incorporated into the zeolite framework. Optionally, a sodium compound may be introduced into the reaction mixture gel either before or after the addition of the acid, preferably before.

Abstract: An activated porous phosphorus/vanadium oxide catalyst adapted for the catalytic oxidation of a hydrocarbon to produce a carboxylic acid anhydride. The catalyst comprises a shaped body having a volume of at least about 0.02 cc, a phosphorus content of between about 1.05 and about 1.20, a B.E.T. surface area of at least about 15 m.sup.2 /g, an average vanadium oxidation state of between about 4.06 and about 4.3, a total pore volume of at least about 0.15 cc/g, a normalized apparent shaped body density of between about 1.0 and about 2.0 g/cc, and a crush strength of at least about 4 pounds. At least about 20% of the pore volume of the catalyst is constituted of pores having a diameter between about 0.1 and about 3.3 .mu.M, and at least about 40% of the pore volume is constituted of pores having a diameter of less than about 0.1 .mu.M.

Abstract: An improved process for the manufacture of maleic anhydride by catalytic oxidation of n-butane in which the feed flow channel to the catalytic reactor contains an autoignition suppression agent containing acid sites or trivalent phosphorus as an ignition inhibiting component. The autoignition suppression agent may also be used in other gas/liquid containment envelopes for flammable mixtures of hydrocarbons and oxygen. A novel apparatus and method are disclosed for assessing the influence of system conditions on autoignition of hydrocarbon/oxygen mixtures.
