摘要：
In a process for the thermal treatment of the precursor material of a catalytically active material in a rotary tube furnace through which a gas stream flows, at least a proportion of the gas stream flowing through the rotary tube furnace is circulated, and the associated rotary tube furnace apparatus and tube-bundle reactors for the partial gas-phase oxidation of acrolein to acrylic acid are loaded with catalysts whose catalytically active material is obtainable by the process for the thermal treatment.
