Abstract: Kinetic and transients studies of dry reforming (DR) of methane to synthesis gas over Pt/Ln0.3Ce0.35Zr0.35Ox (Ln = Pr, Gd, La) catalysts supported on walls of corundum monolith channel as well as situated within it as powders were carried out. Effect of process parameters, composition of complex oxide and Pt loading on catalytic performance was investigated. The lattice oxygen mobility and Pt-support interaction were shown to be main factors controlling catalytic activity and stability. Constants of basic steps of reaction sequence were estimated by numerical analysis of kinetic transients.
