Abstract
Description
発明のN2O除去装置は、図1、図2に示すように、複数のガス流路1とN2O分解触媒が充填された触媒充填層2(2a~2j)を、各々交互に配列して有している。
特許文献1に記載された製法で製造した鉄-ゼオライト触媒を使用する。なお、試験に用いた鉄-ゼオライト触媒は、特許文献1に記載された製法で製造したものであり、直径2mm×長さ5mmのペレット状、ゼオライトはβ型およびMFI型のものである。
使用開始からt日後における、空間速度A/Hr、排ガス温度450℃、還元剤としてアンモニアをNH3/N2Oモル比が1.0~1.3となるように添加した条件下でのN2O分解率y(t,A)は下式となる。
y(t,A)= 100-100×(1- 0.9996t)2000/A
例えば、空間速度2000/Hrでは、使用開始時のN2O分解率はほぼ100%であり、使用期間4年(=1160日)ではN2O分解率は80%となる。
上記の性能を持つ触媒を用いて、10年間、N2O分解率の年平均値が80%以上となるようにN2O除去処理を行うのに必要な触媒量を試算した。対象とする排ガスは、下水汚泥焼却炉からの排出される排ガス(触媒入口温度:450℃)であって、その流速は、52,000N m3/hとした。
