In this paper,the kinds and amount of carbon deposited over Ni base hexaaluminate LaNiAl 11 O 19 catalyst,after both CH 4 decomposition and CO 2 reforming of methane,was determined by means of X ray photoelectron spectroscopy (XPS) and thermogravimetric analysis(TGA) techniques,respectively.Over the catalyst,the rates of carbon deposited vs reaction time were also investigated during the reaction.Two carbon forms were produced,and graphitic carbon was the main and inactive carbon.
