Abstract

Behavior of supported Pt in O2 chemisorption and (O2−H2) titration has been studied. In Pt/SiO2, Pt/α-Al2O3 and Pt/γ-Al2O3 Pto catalysts are characterized by the following stoichiometric coefficients of oxygen adsorption (X), hydrogen adsorption (Y) and oxygen-hydrogen titration (Z) X:Y:Z=1:1:1.5. The co-efficients differ for Pt−Cl/γ-Al2O3 reforming catalysts. This is explained by the presence of electron deficient platium (Ptσ) with a coefficient ratio of X:Y:Z=0.5:2:1.5.
