The gold influence on catalytic activity, stability and carbon deposition of supported nickel based catalysts was studied. The monometallic 5%Ni/Al2O3 and bimetallic 5%Ni-x%Au/Al2O3 (x = 2, 1, 0.5, 0.25, 0.1) systems were prepared by wet impregnation. The catalytic tests in partial oxidation of methane at 25-900 graduate C and long term stability tests at 900 graduate C during 24 h were carried out. The CH4 dissociative decomposition and CO disproportionation processes were run at the same temperature range. Carbon deposition was studied by TG analysis and catalysts investigations by TPR and XRD measurements. The results indicated that gold addition improved both catalytic activity and resistance towards carbon deposition.
