Abstract:

In this study, the spent catalyst of the Reforming unit from Dung Quat Refinery is regenerated. After coke burning, the catalyst is dissolved with an aqua regia to leach Platin and ɤ-Al2O3. The new bifunctional catalyst (PtCuO/γ-Al2O3) based on the spent catalyst is prepared by deposition method and its performance is evaluated for the selective oxidation of carbon monooxide. The characterization techniques are subjected are X-ray diffraction (XRD) analysis, Energy Dipersive X-ray (EDX) spectrocopy, Atomic Absorption Spectrometry (AAS), BET surface area. The result shows that the optimal condition of reaction is in temperature of 75 degree Celcius during 5 hours with solvent Aliquat 336. The new catalyst with 20% wt CuO and 2% wt Platin is a good catalyst in the reaction of transferization carbon monooxide in waste gas
