Different combinations of ceramic open cell foams (OCF) made of silicon carbide (SiC) and zirconia (Zir) coated with 3 wt.% Pd/Co3O4 as the active phase, were studied as structured catalysts for the combustion of CH4 in lean conditions (inlet CH4 concentration: 0.5 and 1 vol.%). The catalytic activity of the structured catalysts was tested at different weight hourly space velocities, with an excess of oxygen. Among the various combinations tested, the reactor made of 1.5 cm SiC + 1.5 cm Zir (1.5SiC/1.5Zir) showed the best catalytic performance, thanks to the different thermal conductivity of the OFC used.

Abstract

Different combinations of ceramic open cell foams (OCF) made of silicon carbide (SiC) and zirconia (Zir) coated with 3 wt.% Pd/Co3O4 as the active phase, were studied as structured catalysts for the combustion of CH4 in lean conditions (inlet CH4 concentration: 0.5 and 1 vol.%). The catalytic activity of the structured catalysts was tested at different weight hourly space velocities, with an excess of oxygen. Among the various combinations tested, the reactor made of 1.5 cm SiC + 1.5 cm Zir (1.5SiC/1.5Zir) showed the best catalytic performance, thanks to the different thermal conductivity of the OFC used.
