Abstract

Language:

Parameters of technique to decarburize from spent petrochemical catalysts via microwave oxidation roasting were investigated. The objective was to determine the impact of various factors on the decarburization percentage of spent petrochemical catalysts. A microwave heating system was employed for the decarburization process, and the results highlighted that the roasting temperature and sample thickness significantly influenced the decarburization efficiency within the studied range. Optimal conditions were identified at a roasting temperature of 600 °C, for a duration of 40 minutes, and a sample thickness of 2 cm, achieving a decarburization percentage of 99.5%. Characterization of the residuum post-microwave decarburization was conducted using field emission scanning electron microscopy (FE-SEM), confirming the effective removal of deposit carbon. This study provides valuable insights into the microwave oxidation roasting technique for enhancing the recovery of active components from spent catalysts.
