Abstract:
The gas‐phase oxidation of acrolein to acrylic acid on a hydrothermally prepared mixed oxide catalyst was investigated by steady‐state isotopic transient kinetic analysis (SSIKTA) as well as different types of concentration‐programmed techniques (CPR‐pulse, CPO) under in situ or process‐relevant conditions. Balancing the amounts of active oxygen gives an overview of the quantities of participating bulk oxygen species. The dynamics of bulk oxygen lead to re‐oxidation processes on the catalyst surface and thus influence the selectivity pattern of the network of acrolein oxidation. Furthermore, the bulk dynamics are activated by temperature.
