Nickel nanoparticles loaded on ceria oxide spheres as catalyst for dry reforming of methane

Abstract

In this paper, nickel particles were loaded on ceria oxide flowers dispersed on a framework of inorganic fibres as catalyst for dry reforming of methane. The tests of dry reforming of methane were performed at 700-800°C. With the Ni/Ce flowers, at 700°C, 750°C and 800°C initial CH4 conversion and after 100 h were 85-63%, 93-88%, 96-87%, respectively. Without the dispersion of ceria oxide flowers, CH4 conversion was 96-70% at 800°C. The samples were reactivated after 100 h of reforming at 800°C and then the reforming reaction was performed again for another 100 h. It was found that the conversion of CH4 after reactivation was higher and more stable than the original catalyst by a few per cent.
