Abstract
New geometries for monolithic catalyst supports are described where, the number of square cells per square inch is increased and the cell wall thicknesses are decreased. Catalytic cycle efficiencies are improved due to an increase in the geometric surface area and reduction in thermal inertia. Physical properties, are discussed and the effect of the new structures on thermal shock resistance, melting, pressure drop, strength, coatability and catalytic activity are described.
By 1981, it is expected that a major share of monolithic converters produced will have substrates of 400 or 600 squares/in and 0.006 inches thick walls.
