In this present work, different supports (CeO2/ZrO2) and different Ni contents based catalysts were prepared by incipientwetness impregnation method and tested in the methane steam reforming (MSR) reaction. The prepared catalysts werecharacterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The XRD analysis confirmed theprepared Ni/CeO2 samples have a pure crystal structure. In the catalytic tests, the effects of reactivity temperature, differentsupport, Ni loading content and the gas hourly space velocity (GHSV) on hydrogen production performance were investigatedsystematically. The results showed that the optimal reaction conditions for MSR by Ni/CeO2 catalyst were as follows: 10 wt% Ni/CeO2, 750 oC, 1500 h−1. The stability test for 12 h at 750 oC indicated that the chosen Ni/CeO2 catalyst had excellentthermal stability.
