Abstract
This study investigated the performance of various designs of ceramic monolithic catalyst supports for automotive emissions control. A test was conducted to examine the relationship of monolith volume, precious metal loading, cell density, and monolith frontal area on FTP emissions. The conclusion is that higher volume and/or higher cell density monoliths will yield improved catalytic performance using equal or less total precious metal per converter.
