  • Patent number: 9422218
    Abstract: A process for recharging the reaction tubes of a tube bundle reactor with a new fixed catalyst bed, in which a heterogeneously catalyzed partial gas phase oxidation of an organic compound had been performed beforehand in a preceding fixed catalyst bed comprising Mo-comprising multielement oxide active compositions to form a steam-comprising product gas mixture, in which, before the recharge, solid deposit which had been deposited on the tube inner walls and comprises molybdenum oxide and/or molybdenum oxide hydrate is brushed away with the aid of a brush.
    Type: Grant
    Filed: June 12, 2015
    Date of Patent: August 23, 2016
    Assignee: BASF SE
    Inventors: Volker Schliephake, Klaus Bott, Rolf-Dieter Becher, Klaus Joachim Mueller-Engel, Jochen Petzoldt, Ulrich Cremer, Andreas Raichle
