-Nanocrystalline calcium aluminate (CaO.۲Al۲O۳) was prepared by a simple co
precipitation method using Poly (ethylene glycol)-block-poly(propylene glycol)-block
poly(ethylene glycol) (PEG-PPG-PEG, MW:۵۸۰۰) assurfactant and employed as
catalyst support for potassium modified ۷wt.% nickel catalysts in methane
reformingwith carbon dioxide. The prepared samples were charactrized by X-ray
diffraction (XRD), N۲ adsorption (BET)and Scanning electron microscopy (SEM)
technique. The results showed relatively high catalytic activity and stability for all
the k modified catalysts. Among the prepared catalysts ۱% K-۷%Ni/CaO.۲Al۲O۳
catalyst showedhigh activity and lower carbon formation in comparison with not
modified catalyst. After five hours on streamthe SEM results showed that with
increase in potassium content the formation of whisker carbon over spent catalysts
decreases.
