Fecralloy Partially Oxidizes Methane Selectively
CPOX catalyst must operate at temperature exceeding 900 oC to achieve 90+% methane conversion and at pressure of 2 MPa to combine with FT process. FeCralloy knitted fibres are ideal supports materials because the oxidized surface alumina layer resists temperature up to 1050 oC . With oxidized FeCralloy as a support, we deposited 0.1%-1% Pt over the fibre surface via solution combustion synthesis. Free of pre-reduction treatment, the selectivity to syngas of the Pt FeCralloy catalyst is superior at both 0.1 MPa and 2 MPa. High pressure restrained the methane conversion and syngas selectivity. Coking deactivates the catalyst, but a quick and simple regeneration step recovers its original reactivity. The FeCralloy surface morphology remains intact after multiple reaction-regeneration cycles.
