Characterization of Cu/ZnO Catalysts from a Methanol Plant

The main objectives of this project are to study the physical and chemical properties of fresh and spent catalysts, to identify the type of decays which led to the catalysts deactivation, and to propose the best handling option of the spent catalyst that is economical and environmental friendly,...

The BET surface area was 109.48 m2/g and 71.15 m2/g for fresh and spent catalysts respectively. The results showed that sulfur and carbon exist in the fresh and spent catalysts. Results of SEM, TPR and TPO analyses showed that the spent catalysts experienced thermal sintering. The spent catalyst cannot be regenerated because of the changes in its physical and chemical properties. The best handling option proposed is disposal and prevention of the catalysts life degradation is preferred because the decayed catalysts cannotbe reused.
