英文摘要	National Key Basic Research Program of China (973) [2010CB226903]; National Natural Science Foundation of China [21073147, 21303140]; Program for Changjiang Scholars and Innovative Research Team in University, China [IRT1036]; Cs-substituted Ni-CsxH3-xPW12O40/SiO2 catalysts were prepared by two-step impregnation and in situ reaction on the support. The catalysts were characterized by N-2 adsorption measurements, inductively coupled plasma atomic emission spectrometry, Raman spectroscopy, in situ X-ray diffraction, NH3-temperature programmed desorption (TPD), H-2-temperature programmed reduction, H-2-TPD, and Fourier transform infrared spectroscopy. The hydrocracking of n-decane was used to study the catalytic performance of the Ni-CsxH3-xPW12O40/SiO2 catalysts. The highest C5+ yield obtained for 8%Ni-50%Cs1.5H1.5PW/SiO2 was superior to those of 8%Ni-50%H3PW/SiO2 and an industrial catalyst. The conversion of n-decane slightly decreased and the C5+ selectivity increased with increasing Cs content in the CsxH3-xPW catalysts. Ni-CsxH3-xPW12O40/SiO2 catalysts possessed relatively large pore sizes, so the improved selectivity might have been due to a weaker acidity of the catalysts. The reduced conversion might have been due to a weaker hydrogenation ability.
