Extruded monolithic catalyst supports

Abstract Extruded monolithic catalyst substrates are widely used in automotive and stationary emissions control reactors. They are increasingly being used, developed, and evaluated in many other reactor applications such as for the chemical processing industries, for catalytic combustion, for ozone abatement, and others. This paper will compare the variety of extruded monoliths used for these applications and will review the forming and characterization of them. Emphasis is on the materials used for automotive substrates, catalysts for selective catalytic reduction of NOx and for new high surface area substrates.
