A particle trap, such as in a honeycomb body, for separating particles out of an exhaust gas flow, includes a flow channel. An exhaust gas flow which includes particles flows through the flow channel. Internals, such as projections, humps, protuberances or the like are situated on one side of the flow channel. An opposite region of a channel wall is completely or partially porous. When a flow of exhaust gas which includes particles flows through the particle trap, the particles are diverted toward the porous channel wall, to which they adhere. They can then be removed again by regeneration. The particle trap and an associated process for separating particles out of an exhaust gas flow, are particularly advantageous when used in the exhaust system of an internal-combustion engine, in particular a diesel engine, specifically and advantageously in combination with a soot filter.
