The Study of Structural Property with Additives over Ni modified Catalyst |
초록 |
The tri-reforming technology, combination of CO2 reforming, steam reforming, and partial oxidation of CH4 in a single reactor, was investigated over Ni based catalysts. The effect of additives such as TiO2 and SiO2 over Ni based tri-reforming catalysts was investigated to prevent the sintering of dispersed Ni particles and the collapse of the microstructure of support during tri-reforming reaction. The catalysts were prepared by physical mixing and impregnation methods. The tri-reforming reaction was carried out with various feed molar ratio of reactants and temperature in a fixed bed reactor system. The characteristics of catalysts were measured by N2 physisorption, XRD, TPR, SEM and TEM. With adding optimal amount of additives, the characteristics of surface and microstructural changes were reduced. |
