Abstract
A porous substrate is described for use as a particulate filter for catalytic or non-catalytic supported soot regeneration methods. The substrate employs catalytic and/or non-catalytic forms of soot regeneration. The substrate has a honeycomb structure and filters, during operation of the particulate filter, nanoparticles in an exhaust gas flow through the porous substrate. The porous substrate is characterized by having a cell density in the region from 200 to 300 CPSI, a wall thickness of 10 to 16 mil, a porosity of 35 to 55% and a pore size of 9 to 15 μm.
Claims21
A particulate filter having catalytic and non-catalytic forms of soot regeneration, comprising:
- a porous substrate having a honeycomb structure and filters configured such that during operation an exhaust gas having nanoparticles flows through the honeycomb structure and filters of the porous substrate, wherein the porous substrate has a cell density in a region from 200 to 300 CPSI.
A particulate filter having catalytic and non-catalytic forms of soot regeneration, comprising:
- a porous substrate having a honeycomb structure and filters configured such that during operation an exhaust with gas nanoparticles flows through the honeycomb structure and filters of the porous substrate, wherein the porous substrate has a cell density in the region from 220 to 270 CPSI, wherein the porous substrate has a wall thickness in the region of 12 mil, wherein the porous substrate has a porosity in the region of 42%, and wherein the porous substrate has a pore size in the region from 11 to 12 μm.
A particulate filter having catalytic and non-catalytic forms of soot regeneration, comprising:
- a porous substrate having a honeycomb structure and filters configured such that during operation an exhaust gas having nanoparticles flows through the honeycomb structure and filters of the porous substrate, wherein the porous substrate has a cell density in a region from 200 to 300 CPSI, wherein the porous substrate has a wall thickness in a region from 10 to 16 mil, and wherein the porous substrate has a porosity in a region from 35% to 55%.
