Catalytic Converters in Electric Cooking
Catalytic converters installed in commercial electric cooking appliances are usually based on metallic honeycomb substrates, which give the best performance in a compact space, without causing too much pressure drop. However, ceramic honeycomb substrates are sometimes used as well, and these may be advantageous if they are located in the microwave zone. Knitted wire substrates are also the best choice in some applications.

One of the key requirements of a catalytic converter designed for a cooking appliance in which the air recirculates is that the coating adhesion must be excellent, otherwise the coating may fall off and contaminate foodstuffs during cooking. It is also essential that the catalytic converter materials are resistant to corrosion.
In the domestic market, catalytic converters are sometimes installed in pyrolytic self-cleaning ovens, and in these cases ceramic honeycombs are normally used due to their low cost when purchased in large quantities.
