摘要：
It was revealed that Pt-Pd bimetal supported on USY zeolite showed high and stable catalytic activity for the hydrodesulfurization of thiophene at 400 degrees C and this activity was higher than that of commercial Co-Mo/Al2O3 catalyst. It was concluded that the strong Bronsted acid site of USY and spillover hydrogen formed on Pt-Pd bimetal particle in Pt-Pd/USY catalyst play an important role for the hydrodesulfurization of thiophene.
