Partial oxidation of methane into syngas on Pt-supported mixed oxides: effect of surface/lattice oxygen mobility in complex oxides on the kinetic features of the reaction and performance stability

Partial oxidation of methane (POM) into syngas at short contact times on two catalysts containing Pt/PrCeZrO and Pt/LaCeZrO deposited on single channels of a corundum monolithic substrate was investigated. The effects of the catalyst composition, pretreatment and process parameters on activity and selectivity of the syngas formation were studied. The oxygen mobility in complex oxides was shown to determine both their stability to coking and realization of a direct selective oxidation route of the syngas generation.
