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.
