Abstract
Low temperature calcined catalyst, developed by Matsushita Electric Industrial Co., Ltd. has met well to consumer desire and several social problems in terms of electric appliances as a home-use catalyst. There are problems involving energy saving and the westernized way of living and eating. As a result, this catalyst has earned a good reputation as a home-use catalyst in the market of cooking appliances and heating equipments.
Depending on these appliances, three types (A, B, C) of these catalysts are available. Two types (A, B) are composed of MnO2, Zn-Mn-FeOx and Al2O3CaO and the B-type contains a platinum group catalyst in addition to the fundamental constituent. The C-type catalyst is composed of TiO2, SiO2 and Al2O3CaO which contains platinum group metals. These catalysts are the low temperature calcined type, have a high specific surface area, and washcoatless catalyst because of using Al2O3CaO.
This low temperature calcined catalyst, has actually been used for various kinds of home-use appliances for the past 10 years. Because of its high catalytic performance and inexpensive cost, it is expected that it will be applied in many fields of electrical appliances not only in Japan, but also in the global market.
