摘要

A thermal plasma process for the recovery of the spent alumina-supported platinum catalyst (Pt/Al₂O₃) and reduction of platinum oxide (PtO₂) was developed. The spent Pt/Al₂O₃ and PtO₂ catalysts were sintered at >1500K under plasma condition and were reformed or reduced to metallic platinum, which were proven by XRD and EDX. Results from SEM and BET specific surface area analyses indicated that the organic tar with the intermolecular and intramolecular water on the surface of the spent catalysts was decomposed and converted to syngas (CO, CO₂, and H₂), which might be the reducing agents in the process. Time-programmed hydrogenation study of urocanic acid was carried out to compare the catalytic efficacy of recovery and fresh Pt/Al₂O₃ catalysts. The experimental result indicated that the plasma sintered Pt/Al₂O₃ catalyst showed the similar catalytic efficacy with respect to the fresh catalyst.
