초록
Methane steam reforming (MSR) reaction is a promising industrial hydrogen production technology. Mg-Ni/CeO2 catalysts atdifferent Mg/Ni ratios of 6/4, 7/3, 8/2 and 9/1 with total loading of 10 wt% were used as catalysts for hydrogen production. The characterization techniques such as XRD, SEM and EDS were carried out on fresh and spent samples. Results showedthat the optimum Mg addition content for Mg/Ni-CeO2 is 2%. The process optimization of reaction parameters wereconducted by evaluating the catalytic activity. The stability of optimal Mg-Ni/CeO2 catalyst at 700 oC is examined for 8 h onstreamreaction. It reveals that Mg/Ni-CeO2 still maintains a relatively high catalytic activity after 8 h stability test.
