AbstractMgO, TiO2, and Mg0.5Ti0.5Ox Composite oxides were prepared by the sol-gel technique. Ni was supported on these oxides by the wet impregnation method. No peak of free NO was observed in all X-ray diffraction patterns of the catalysts. The addition of Ti to the NiO-MgO system prevents the formation of solid solution but does not decrease the dispersion of Ni particles. The catalytic performance of the catalysts for tri-reforming of methane was investigated in a fixed-bed flow reactor at 850 degrees C under 1.0 MPa with space velocity of 31 800 ml/(g center dot h) and feed composition of n(CH4): n(CO2): n(H2O): n(O-2) = 1:0.48:0.54:0.1. The catalytic activity of Ni/TiO2 and Ni/MgO decreases during the reaction period. The Ni/Mg0.5Ti0.5Ox catalyst has a relatively high stability, which is mainly dependent on the moderate interaction between the metal and the support and the moderate ability to be reduced.
