Claim 12:
13. A method comprising:
introducing a gas into an inlet of an emissions control device, the emissions control device comprising:
a housing comprising the inlet and an outlet;
an inductive heater disposed within the housing;
a conductive layer disposed within the housing radially outside of the inductive heater, wherein the conductive layer is gas permeable and thermally conductive; and
a catalytic layer disposed within the housing around the conductive layer, wherein the catalytic layer comprises inorganic fibers and a catalyst;
wherein the catalytic layer forms a permeable seal between the inlet and the outlet;

using the inductive heater, heating the conductive layer;
transferring heat from the conductive layer to the catalytic layer or the gas via conduction, convection, and/or radiation;
catalytically oxidizing or reducing components of the gas at the catalytic layer; and
exhausting the oxidized or reduced gas through the outlet of the emissions control device.
