Abstract
A contact material composition of an intimately mixed halogencontaining mixed oxide of at least one cationic species of a naturally occurring Group IIIB element, at least one cationic species of a Group IIA metal of magnesium, calcium, strontium and barium and at least one cationic species of germanium and gallium, as well as methods for hydrocarbon conversion using such contact material compositions are provided.
Claims26
A method for converting lower alkanes to a product composition comprising a higher molecular weight hydrocarbon, said method comprising contacting a feed composition comprising at least one lower alkane material with an intimately mixed halogen-containing mixed oxide contact material comprising:
- a) at least one cationic species of a naturally occurring Group IIIB element;
- b) at least one cationic species of a Group IIA metal selected from the group consisting of magnesium, calcium, strontium and barium;
- and
- c) at least one additional metal cationic species selected from the group consisting of germanium and gallium;
- with said contacting being at oxidative coupling reaction conditions and in the presence of oxygen.
A method for converting lower alkanes to a product composition comprising a higher molecular weight hydrocarbon, said method comprising contacting a feed composition comprising at least one lower alkane material with an intimately mixed alkaline earth halide-containing mixed oxide contact material comprising an alkaline earth element selected from the group consisting of magnesium, calcium, strontium and barium and a halogen selected from the group consisting of fluorine and chlorine, the contact material also comprising:
- a) at least one cationic species of a naturally occurring Group IIIB element selected from the group consisting of yttrium, lanthanum, neodymium, samarium and ytterbium, and
- b) at least one additional metal cationic species selected from the group consisting of germanium and gallium;
- with said contacting being at oxidative coupling reaction conditions and in the presence of oxygen.
A method for converting methane to a product composition comprising a higher molecular weight hydrocarbon, said method comprising contacting a feed composition comprising methane with an intimately mixed barium chloride-containing mixed oxide contact material of:
- a) a cationic species of yttrium, and
- b) a cationic species of germanium, with the contacting being at oxidative coupling reaction conditions and in the presence of oxygen.
A composition comprising an intimately mixed halogen-containing mixed oxide of:
- a) at least one cationic species of a naturally occurring Group IIIB element;
- b) at least one cationic species of a Group IIA metal selected from the group consisting of magnesium, calcium, strontium and barium;
- and
- c) at least one additional metal cationic species selected from the group consisting of germanium and gallium.
