Ceramic Catalyst Support

Many intermediate and end products in the chemicals industry can only be produced with the help of catalysts.
Ceramic catalyst support. They are primarily used in selective oxidation processes. Reticulated ceramic foams have properties that make them attractive as catalyst supports they exhibit extremely high porosities 85 90 formed by megapores 0 04 1 5 mm in diameter with spherical like cells connected through windows the pore structure of a typical commercial product shown in fig. Vff is the largest manufacturer of inert balls catalyst bed support media in europe. Ceramic catalyst carriers form an important group of commonly used carrier materials in heterogeneous catalysis.
A catalyst support provided with an activated alumina layer which is formed on the surface of the ceramic honeycomb structure is disclosed.

In table i some commonly used ceramic catalyst support materials for the vehicle gas exhauster system are summarized such as cordierite mullite a al2o3 zirconia silicon carbide silicon nitride etc 12 13 however all these support materials are insulators and this hinders. The catalyst support of the present invention is formed of ceramic such as cordierite of which coefficient of thermal expansion is lower than alumina and is provided with microcracks which occur when the honeycomb structure is formed. Due to heat losses from the catalytic converter the center region of the support experiences higher temperatures than its periphery which induces tensile stresses in the outer region the center region. One of the key durability requirements of ceramic catalyst supports is an adequate thermal shock resistance to survive temperature gradients.
