  • Process for preparing maleic anhydride in a microchannel reactor
    Publication number: 20070270597
    Abstract: The present invention relates to a process for preparing maleic anhydride by heterogeneously catalyzed gas-phase oxidation of a hydrocarbon, which comprises feeding a hydrocarbon-comprising stream and a stream comprising oxygen or an oxygen source into a microchannel reactor and carrying out the reaction to form maleic anhydride in the explosive range in the microchannel reactor comprising the catalyst.
