Claims23
An exhaust emission purification device, comprising:
- a catalyst body including a plurality of flow channels extending between an intake side and a discharge side of the catalyst body for a passage of an exhaust gas,
- wherein the catalyst body comprises a sintered catalyst material.
A method for producing a catalyst body, comprising:
- combining a metal powder mass of a catalyst material with a binder and filling the combined metal powder mass and binder into a catalyst body molding tool to produce a preform;
- hardening the binder by introducing heat;
- and
- subjecting the preform to pressure-free sintering to thereby cause the binder to evaporate.
