Why is it necessary to regenerate cobalt/molybdenum catalysts? Answer: The exhaust gas purification reactor of this unit is equipped with a cobalt/molybdenum catalyst, which facilitates the reaction of S and SO2 with H2. After the catalyst has been in use for a certain period of time, carbon black present in the reaction gases deposits on the catalyst bed, reducing its activity and increasing the pressure drop across the reactor bed. Therefore, it is necessary to regenerate the catalyst when the unit is shut down.
