Patent attributes
A catalytic converter designed to be integrated into a food-cooking appliance and to act, during a cooking cycle in a closed atmosphere and without oxygen being admitted from the outside, to treat the odors in the cooking fumes before the fumes are discharged to the outside, the converter comprising a basic substrate (30) provided with perforations (31) for passing the cooking fumes to be treated, the substrate (30) being coated with an intermediate layer (32) having a large surface area, itself provided with a surface component (33) formed of an inorganic solution based on precious metals so as to form the catalytic active layer of the converter, the intermediate layer (32) comprising alumina and cerine so as to form an intermediate layer (32) with a surface area of not less than 150 square meters per gram (m2/g), the amount of alumina/cerine added to the basic substrate (30) lying in the range 30 g/m2 to 35 g/m2, including 15 g/m2 of cerine to 25 g/m2 of cerine. The catalytic converters, in particular, for a deep fryer.
