| Abstract: |
| TiPW/SA was produced using the sol-gel method and characterized by FT-IR and N2 adsorption-desorption. Taking the gasoline with a sulfur compounds content of 300 mg/kg as experimental material, the catalytic oxidation and adsorption desulfurization performance of TiPW/SA was analyzed. The results showed that all the loaded catalysts keep the Keggin structures, and TiPW/SA has a supermicroporous structure, and the specific surface area is 325 m2/g. The analysis also suggested that the desulfurization rate of TiPW/SA under the optimal reaction condition could reach 92.08%. |
