| Abstract: | A series of La-Ni2P/SBA-15 catalysts with different La contents were prepared by impregnating nickel nitrate,diammonium hydrogen phosphate,and lanthanum nitrate on SBA-15 support and followed by TPR method.The structure of the catalysts was characterized by XRD,N2 adsorption-desorption and XPS.The catalytic performance of the catalysts for hydrodesulfurization(HDS) was evaluated using DBT as model compound.The results indicated that the addition of La increased the surface area and pore volume of the cataly... |
