Parameters of technique to decarburization of spent petrochemical catalysts via microwave oxidation roasting were investigated base on the thermogravimetric analysis. The results showed that the decarburization rate of spent petrochemical catalysts was significantly affected by roasting temperature and sample thickness in the range studied. The optimized conditions were as follows: roasting temperature 600℃, roasting time 40 min and 2cm, respectively. The decarburization rate of spent petrochemical catalysts was 99.5% under the optimization conditions. The residuum after decarburization was characterized by FE-SEM. Energy spectrum reveals that it is feasible to decarburization by microwave oxidation roasting from spent petrochemical catalysts.
