Study of Ammonia Storage and Delivery Methods for SCR System

SCR 用アンモニア貯蔵法の検討

The purpose of this study is to evaluate two methods of directly supplying ammonia for a selective catalytic reduction (SCR) deNOx system of a diesel engine. Unlike urea-SCR, direct ammonia supply methods for SCR enable NOx reduction in low temperature ranges. One supply method uses an ammonia salt called ammonia carbamate. This method generates large amounts of ammonia, but requires an apparatus temperature higher than 80°C to avoid re-precipitation of the ammonia carbamate. In contrast, a method utilizing an ammonia storage material is more compact than liquid urea and re-precipitation does not occur.ディーゼルエンジンから排出されるNOx を浄化する技術としてアンモニアをSCR に直接供給する方法が挙げられる．本報告ではアンモニア直接供給による触媒低温度域におけるNOx 低減効果，ならびにアンモニア塩やアンモニア吸蔵材を用いたアンモニア貯蔵法を検討した結果について報告する．
