Abstract
The catalytic decomposition of CH4 for the production of pure H2 is carried out over Ni supported on hydroxyapatite [Ca5(PO4)3(OH)] catalysts at 650 °C and atmospheric pressure. CH4 decomposition activity is decreased with time on stream and finally deactivated completely. The physicochemical properties of the fresh catalysts are characterized by XRD, DTA/TG, TPR and SEM techniques along with CHNS analyses of the used samples. It is found that the 30 wt% Ni/HAp displayed higher H2 production rates over the other Ni loadings, which is correlated with Ni metal surface area measured by O2 pulse chemisorption.
