Abstract:
The catalytic partial oxidation of methane was studied over single channels of monolith catalysts
Pt/PrCeZrO/α-Al2O3 and Pt/GdCeZrO/α-Al2O3 using the temporal analysis of products (TAP) and kinetic
transients. Effects of catalyst composition, oxidation state, time offset between O2 and CH4 pulses on activity,
selectivity and dynamics of product formation were elucidated. Realization of the direct pyrolysis–СH4 partial
oxidation route was reliably established. This route is favored by optimum lattice/surface oxygen mobility and
reactivity controlled by the dopant type (Gd, Pr) and oxidation state of the complex cerium/zirconium oxide.
