Production of hydrogen by methane dry reforming: A study on the effect of cerium and lanthanum on Ni/MgAl2O4 catalyst performance

During this study, the catalytic activity was compared at atmospheric pressure at 750 degrees C during 4 h then 650 degrees C during 4 h toward methane dry reforming (DRM) reaction with a molar ratio CH4/CO2 = 1/1 and a Weight Hourly Space Velocity (WHSV) of 60.000 mLg(-1).h(-1). The results showed that among the different catalysts 1.5Ce-Ni5/MgAl2O4, synthesized with alumina from Alfa Aesar, exhibited the best catalytic activity for DRM.

Hydrogen production from dry reforming of methane (DRM) was investigated on different Nickel based catalysts deposited on MgAl2O4. MgAl2O4 spinel was prepared using gamma-Alumina supplied from different manufacturers (Sigma Aldrich, Alfa Aesar and Degussa) with low and high specific surface area. Moreover, the influence of different parameters on the catalytic activity on methane dry reforming was studied such as the effect of Ni content, the effect of commercial alumina and the effect of doping nickel with cerium and lanthanum.
