| Abstract: | The oxidative desulfurization of FCC gasoline was investigated using HPWA/HY, HP WA/SBA-15, and HPWA/HY-SBA-15 as catalysts, individually. Micro-mesopore structured HPWA/HY-SBA-15 with 20% of phosphotungstic acid exhibited the optimal catalytical performance and the sulfur content of FCC gasoline dropped to 18 μg/g after adsorption under optimal conditions: HY content of 40% in composite zeolite and reaction temperature of 40°C for 90 min. |
