  • Patent number: 7205447
    Abstract: The present invention provides a process for removing an oxygenate impurity selected from aldehyde and/or ketone, from an olefinic product stream. A product stream is contacted with a metal oxide-containing catalyst in the presence of a C1 to C6 alcohol under conditions sufficient to convert the oxygenate impurity to an olefin and/or oxygenate of higher carbon number than the aldehyde and/or ketone. The aldehyde can be C2 to C5 aldehyde and the ketone can be C3 to C6 ketone. The metal oxide-containing catalyst typically comprises an oxide of at least one metal selected from the group consisting of Group 2 metals, Group 3 metals (including Lanthanide and Actinide series metals), and Group 4 metals.

  • Patent number: 7195746
    Abstract: A method for making an organometallic treated molecular sieve is described in which a molecular sieve having at least one hydroxyl group and at least [AlO2] and [PO2] tetrahedral units and having an average pore dimension less than or equal to about 5 ? is contacted with a solution comprising an organometallic compound and a non-proton donating solvent. The resulting organometallic treated molecular sieve has enhanced ethylene and/or propylene selectivity when used in the conversion of organic oxygenates to olefins. The ethylene and/or propylene selectivity, as well as catalyst life, are further enhanced when the resulting organometallic treated molecular sieve is combined with an oxide of at least one metal selected from Groups 2, 3 and Group 4 of the Periodic Table.
