<p><P>PROBLEM TO BE SOLVED: To provide a multi-staged catalyst system and a method for converting alkanes to alkenes and their corresponding oxygeneated products. <P>SOLUTION: Alkanes, unsaturated carboxylic acids, saturated carboxylic acids and their higher homologs are accumulatively prepared from corresponding alkanes by using a multi-staged catalyst system. In the preparation, steam cracking of alkanes to corresponding alkenes at flame temperatures and at short contact times is performed in combination with one or more oxidation catalysts for catalytically converting the corresponding alkanes to further corresponding oxygenated products using short contact time reactor conditions. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
