“…Therefore, selectivity towards partial oxidation products on the oxidation step of the CPOX process increases exponentially with the increase in the catalyst temperature. This was also observed in our previous work on methane oxidation under fuel rich conditions over the catalysts with externally controlled surface temperature [26].…”

In this work we demonstrate catalytic partial oxidation of methane into syngas at pressures up to 0.8 MPa, power densities up to 15 MW/L and selectivity greater than 85%. The product composition profiles indicate high initial selectivity to CO and low initial selectivity to H 2 , suggesting direct partial Oxidation of methane primarily into CO and water, while most hydrogen is produced in the consecutive steam reforming of methane.

“…No similar trend was found without catalyst; non-catalytic limits were nearly symmetric about stoichiometric. As shown previously [16,19,20], at low temperatures, O(s) coverage on Pt is nearly complete, thus fuel can not reach the catalyst surface. Under these conditions, excess fuel is required to prevent O(s) coverage of the Pt catalyst surface.…”
