HONEYCOMB BODIES HAVING AN ARRAY OF THROUGH CHANNELS WITH A RANGE OF HYDRAULIC DIAMETERS

Abstract:

A ceramic honeycomb body, suitable for use in exhaust gas processing, includes a honeycomb structure having a plurality of through-channels, a first portion of the plurality of through-channels have a first hydraulic diameter dh1, a second portion of the plurality of through-channels have a second hydraulic diameter that is smaller than the first hydraulic diameter dh1, the first hydraulic diameter dh1 is equal to or greater than 1.1 mm, and the first and second portions of through-channels, taken together, have a geometric surface area GSA greater than 2.9 mm.sup.-1. Diesel oxidation catalysts and methods of soot removal are also provided, as are other aspects.
