| 摘要 |
The invention concerns a catalytic converter designed to be incorporated in a food cooking appliance for treating, during a cooking cycle under closed atmosphere without external oxygen input, the cooking flux smells before said flux is expelled outside, said converter comprising a base substrate (30) provided with perforations (31) allowing through the cooking flux to be treated, said substrate (30) being coated with an intermediate layer (32) having a wide surface area, provided itself with a surface component (33) formed with an inorganic solution based on precious metal to form an active catalytic layer of the converter. The invention is characterised in that the intermediate layer (32) comprises alumina and albanite to form an intermediate layer (32) with a surface area not less than 150m<2>/g, the alumina/albanite input on the base substrate (30) ranging between 30 and 35 g/m<2>, of which 15 to 25 g/m<2> of albanite. The invention concerns catalytic converters, in particular for fryers.
