摘要：
The invention relates to a method for the thermal treatment of the precursor mass to an active catalytic mass in a rotating tube oven (2) with a through gas flow, whereby at least a partial amount of the gas flowing through the rotating tube oven is run in a loop (19). The invention further relates to the corresponding rotating tube oven device and tube bundle reactors, for the partial gas phase oxidation of acrolein to give acrylic acid, which are coated with the catalyst, the catalytic active mass of which may be obtained after the method for thermal treatment.
