Monolithic porous body for use as catalyzed particle filter, has input channels surrounded by output channels so that no porous partition of one of input channels is common with porous partition of other of input channels

摘要

The body has a honeycomb structure comprising a multiplicity of channels (16) delimited by porous partitions (18). A part of the channels is closed at one of inlet and evacuation faces (12, 14) for forming input channels (20), and the other part of the channels is closed at the other face for forming output channels (22). The channels comprise a transversal section in the form of polygon with three sides. The input channels are surrounded by the output channels so that no porous partition of one of the input channels is common with a porous partition of the other of the input channels.
