    • 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.
    • 本发明提供从烯烃产物流中除去选自醛和/或酮的含氧化合物杂质的方法。 在足够将含氧化合物杂质转化为烯烃和/或其混合物的条件下,将产物流与C 1 -C 6醇存在下与含金属氧化物的催化剂接触,和/ 或高于醛和/或酮的碳数的含氧化合物。 醛可以是C 5到C 5的醛,酮可以是C 3至C 6 - 酮。 含金属氧化物的催化剂通常包含选自第2族金属,第3族金属(包括镧系元素和锕系金属)和第4族金属中的至少一种金属的氧化物。
