Partial oxidation of methane into synthesis gas over a Pt-supported complex fluorite-like oxide: one-channel studies in realistic feeds

Partial oxidation of methane (POM) into synthesis gas over a single channel of monolithic catalyst 1.4 wt% Pt/Gd0.3Ce0.35Zr0.35Ox/alpha-Al2O3 was investigated. The effect of the catalyst pretreatment and of the process parameters (temperature, contact time, feed composition) on the catalytic activity and synthesis gas (syngas) selectivity was studied at conditions close to realistic ones with a minimum impact of the mass and heat transfer phenomena. Experimental data are in favor of the direct route of the syngas formation via the methane pyrolysis-selective oxidation sequence.
