The characterization of Ni-based catalysts for autothermal reforming process
A simple technique approach was used to characterize the structural and chemical properties of CoO-NiO catalysts supported on delta-Al2O3, HZSM-5 and MgO-Al2O3.The morphology of the catalysts was studied by X-Ray diffraction to determine the phase composition and the particle size of the catalysts....

| description | A simple technique approach was used to characterize the structural and chemical properties of CoO-NiO catalysts supported on delta-Al2O3, HZSM-5 and MgO-Al2O3.The morphology of the catalysts was studied by X-Ray diffraction to determine the phase composition and the particle size of the catalysts. Temperature-programmed reduction (TPR) reveals the formation of NiO and Co3O4 in dependence on temperature in case of catalysts supported on delta-Al2O3 and MgO-Al2O3 at higher metal loading. The catalysts
supported on HZSM-5 also show appearance of NiO, CoO and Co3O4, which could lead to deactivation of the catalysts via formation of coke on the catalyst surface. The formation of NiO-CoO-MgO solid solution supported on MgO-Al2O3 exhibited stronger interaction between metal and support thus can make the catalysts more resistant to sintering and enhance the structure durability of catalyst in high temperature methane reforming process. |
