TEXTURES OF THERMALLY STABLE AUTOMOTIVE CATALYST CARRIERS

The catalyst carrier for automotive emission control should remain stable after exposure to high temperatures. The relationship between mechanical properties and textures of crystalline alumina carriers has been investigated. Results are; (1) The mechanical strength and attrition resistance of carriers are affected by textures. Carrier types B and C have many small regular crystals within their macro pores. They show highly stable properties up to 1100 degrees C. (2) Shrinkage of the carrier is affected by transformation of alumina. Carriers with smaller shrinkage at 1100 degrees C show rather slow rate of transformation. (Author/TRRL)
