متن کاملEffect of K2O on the catalytic performance of Ni catalysts supported on nanocrystalline Al2O3 in CO2 reforming of methane
CO2 reforming of methane (CRM) over unpromoted and potassium promoted Ni/Al2O3 catalysts was studied. The catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption (BET), temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and scanning electron microscope (SEM) techniques. The obtained results showed that addition of K2...
متن کاملNi-SiO₂ catalysts for the carbon dioxide reforming of methane: varying support properties by flame spray pyrolysis.
Silica particles were prepared by flame spray pyrolysis (FSP) as a support for nickel catalysts. The impact of precursor feed rate (3, 5 and 7 mL/min) during FSP on the silica characteristics and the ensuing effect on catalytic performance for the carbon dioxide, or dry, reforming of methane (DRM) was probed. Increasing the precursor feed rate: (i) progressively lowered the silica surface area ...
متن کاملHighly Dispersed Nickel-Containing Mesoporous Silica with Superior Stability in Carbon Dioxide Reforming of Methane: The Effect of Anchoring
A series of nickel-containing mesoporous silica samples (Ni-SiO₂) with different nickel content (3.1%-13.2%) were synthesized by the evaporation-induced self-assembly method. Their catalytic activity was tested in carbon dioxide reforming of methane. The characterization results revealed that the catalysts, e.g., 6.7%Ni-SiO₂, with highly dispersed small nickel particles, exhibited excellent cat...
متن کاملA Comparison Study on Carbon Dioxide Reforming of Methane Over Ni Catalysts Supported on Mesoporous SBA-15, MCM-41, KIT-6 and γ-Al2O3
The activity of Ni supported on mesoporous SBA-15, MCM-41, KIT-6, and a sol-gel prepared Ni/γAl2O3, for catalysing methane dry reforming was investigated. The chemical and physical characteristics of the catalysts before and after catalytic testing were investigated using X-Ray diffraction, X-ray Photoemission Spectroscopy, Transmission Electron Microscopy, Scanning Electron Microscopy / Energy...
