Title:
POROUS HONEYCOMB FILTER
Document Type and Number:
WIPO Patent Application WO/2006/030811
Kind Code:
A1
Abstract:
A porous honeycomb filter having a controlled pore distribution, characterized in that a pore volume of the pores having a pore diameter of 15 μm or less is 0.07 cc/cc or less, and a pore volume of the pores having a pore diameter of 40 μm or more is 0.07 cc/cc or less. The above porous honeycomb filter does not show the decrease in the capturing efficiency even when the porosity thereof is varied, and thus can combine good capturing efficiency and a low pressure loss.
