제목 Ni/MgO-MgAl2O4 catalysts with bimodal pore structure for steam-CO2-reforming of methane
초록 Ni-base structured catalysts have been widely used on the steam CO2 reforming of methane for the production of syngas in GTL-FPSO. Much efforts are still necessary to acheive high catalytic activity by elaborate control over the morphology and structure of nano-structured catalysts.
Bimodal pore catalyst supports are reported to be high catalytic activity and the active phase can ve dispersed well throughout the pore system, thus making possible to obtain a large active surface area per unit weigh.
For this study, bimodal catalyst supports consisting of MgO-MgAl2O4 composite with meso-macro pore structure were fabricated from decomposition of pellet mixtures of MgCO3 synthesized under a supercritical carbon dioxide. After Ni impregnation, the Ni-based structured catalysts were carried on structural and catalytic activity studies at various conditions.  
As a result, an enhancement in catalytic activity of catalysts with bimodal structures  by the conversion of CH4, CO2 was found due to the enhanced dispersion and mass transfer in the pores.
