Abstract

A plate-type catalytic converter includes a stack of first plates and second plates. In operation, a flow medium flows from an inflow side to an outflow side. Leading edges of the second plates are set back in the direction of the outflow side relative to leading edges of the first plates. Catalytic activity can therefore be significantly improved as compared with a plate-type catalytic converter of conventional construction for the same physical volume, since the contribution toward the catalytic activity of the catalyst which is provided by turbulent flow is increased without increasing pressure loss or an additional risk of blockage by ash.
