Multiple bed catalyst

摘要

The catalyzer (1) has a housing (2) containing 2 catalytic monoliths (3,4) arranged axially one after the other in the exhaust gas flow, both enclosed by a common heat-resistant mat (5), supporting the monoliths in the catalyzer housing. At least 2 heat-resistant peripheral spacer elements (9) are fitted in the axial gap between the monoliths.
