Effect of Support on Stability and Coke Resistance of Ni-Based Catalyst in Combined Steam and CO₂ Reforming of CH₄.

ABSTRACT: Ni-based catalysts dispersed on different supports (MgO-α-Al₂O₃, CeO₂, SBA-15, and MgO-SBA-15) were prepared by the impregnation method. Characteristics of the catalysts, including specific surface areas (N₂ physisorption), crystalline phase compositions (powder X-ray diffraction, Raman spectroscopy), reducibility (hydrogen temperature-programmed reduction, H₂-TPR), and morphology (scanning electron microscopy (SEM) and transmission electron microscopy, TEM)) were investigated. The activity and stability of the catalysts were tested for the combined steam and CO₂ reforming of methane at 700 °C in a microflow system. The results show that the catalysts exhibit high activity in the BRM reaction. At 700 °C, the conversion of CH
