Honeycomb bodies having an array of channels with different hydraulic diameters and methods of making the same

A catalytic honeycomb body comprising:

• a matrix of intersecting porous walls forming first channels and second channels, each first channel having a first hydraulic diameter, and each second channel having a second hydraulic diameter, wherein the second hydraulic diameter is smaller than the first hydraulic diameter;
• and
• plugs disposed in a percentage of the second channels at an outlet end, the percentage of the second channels with plugs is greater than zero and less than or equal to 15%;
• and
• a catalyst disposed on the porous walls of the first channels and the second channels;
• wherein the intersecting porous walls have a transverse wall thickness (Tw), a channel density (CD), an average bulk porosity (% P), and a median pore diameter (d50), wherein:
• Tw≤0.20 mm,
• CD≥62 channels per cm2,
• % P≥50%, and
• 4.0 μm≤d50≤30.0 μm.
