Abstract
Ammonia storage is a challenge in the selective catalytic reduction of NO x in vehicles. We propose a new system, based on metal ammines as the ammonia source. In combination with iron containing zeolites as the SCR catalyst it should be possible to obtain a low temperature system for NO x removal.
