摘要：
The Pt/AlSBA-15 catalyst showed high and stable catalytic activity for the hydrodesulfurization of thiophene at 350degreesC and this activity was higher than those of Pt/SBA-15 and commercial CoMo/Al2O3 catalysts. The Pt/AlSBA-15 catalyst has high sulfur-tolerant property toward hydrogen sulfide formed in hydrodesulfurization of thiophene. The Broensted acid sites of AlSBA-15 and the spillover hydrogen formed on Pt particle in Pt/AlSBA-15 catalyst play an important roles for the hydrodesulfurization of thiophene.
