摘要
The invention relates to a porous substrate for use as a particulate filter preferably for automotive and non-automotive applications. The substrate employs catalytic and non-catalytic forms of soot regeneration. The substrate has a honeycomb structure and filters, during operation of said particulate filter, nanoparticles in an exhaust gas flowing through said porous substrate. The porous substrate is characterized by having a cell density in the region from 200 to 300 cpsi (31-47 channels/cm2), a wall thickness of 10 to 16 mil (250-406 μm), a porosity of 35 to 55% and a pore size of 9 to 15 μm.
