Abstract:
A series of Ni2P-modified MoS2/γ-Al2O3 catalysts with constant Mo contents were prepared by the thermal decomposition of ammonium tetrathiomolybdate and nickel hypophosphite under N2 atmosphere.The structure of the catalysts was characterized by N2 adsorption-desorption, X-ray diffraction, and high-resolution transmission electron microscopy.The catalytic performance of the catalysts for hydrodesulfurization(HDS)was evaluated in a fixed-bed microreactor using dibenzothiophene(DBT)as the model compound.The results indicated that when the amount of Ni2P was 4%(mass), the catalyst showed a relatively high catalytic activity with a strong preference for the hydrogenation desulfurization(HYD)pathway.Its hydrogenation selectivity(2.11)was 2.9 times that of reference catalyst(0.72)at 300℃.The addition of Ni2P had an effect on the average stacking number and slab length of MoS2.
