International Classification:
B01J 29/89, B01J 29/86, B01J 29/44, B01J 29/88
US Classification:
585417, 502 74
Abstract:
This invention is for a catalyst for conversion of hydrocarbons. The catalyst contains a zeolite with one element from Group 13, Group 14, or the first series transition metals and, optionally, germanium and/or aluminum in the zeolite framework. At least one Group 10 metal, such as platinum, is deposited on the zeolite. Examples of the elements in the framework are tin, boron, iron or titanium. The catalyst is prepared by synthesizing a zeolite with one element from Group 13, Group 14, or the first series transition metals and, optionally, germanium and/or aluminum in the zeolite framework; depositing the metal; and calcining after preparation of the zeolite and before or after depositing the metal. The catalyst may be used in a process for the conversion of hydrocarbons, such as propane to aromatics, by contacting the catalyst with alkanes having 2 to 12 carbon atoms per molecule and recovering the product.

International Classification:
C10G 35/06
US Classification:
208 65
Abstract:
This invention relates to a process for the increasing the octane number of a naphtha hydrocarbon feed having a predominantly paraffin content with a germanium-containing zeolite catalyst. The catalyst is a non-acidic germanium zeolite on which a noble metal, such as platinum, has been deposited. The zeolite structure may be of MTW, MWW, MEL, TON, MRE, FER, 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. The hydrocarbon feed may contain sulfur up to 1000 ppm. The present invention could be applicable to a feedstream which is predominantly naphthenes and paraffins.

US Classification:
423705, 423707, 423713, 423DIG 22
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:
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 Cto Calkanes, 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.
Process For Alkane Aromatization Using Platinum-Zeolite Catalyst

Assignee:

International Classification:
C07C 2/52
US Classification:
585418, 585419
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.
