Abstract
A device for oxidizing a gas mixture that includes at least one hydrocarbon and oxygen. The device contains a porous solid that consists of zirconia. At least one metal having a catalytic oxidation activity, for example platinum or palladium, is deposited on the solid support. The device also contains an induced-air catalytic burner for the catalytic combustion of gaseous hydrocarbon mixed with atmospheric air and a member for dissipating the heat generated within the solid support. The device develops an average thermal power of at least 10 W/cm.sup.2 and an average temperature within the support of at least 700.degree. C.
Claims17
An induced-air catalytic burner for catalytic combustion of a gaseous hydrocarbon mixed with atmospheric air, said burner comprising:
- a member for admixing said gaseous hydrocarbon with said atmospheric air;
- a permeable support made of a thermochemically inert material, said permeable support comprising an inlet face for accepting a mixture to be burned and an outlet face for discharging waste gases, wherein an internal surface of said permeable support is at least partly coated with a porous solid phase comprising zirconia particles having a particle size of between 1 and 5 .mu.m, onto which is deposited a metal having a catalytic oxidation activity;
- and
- means for dissipating heat generated within said support.
