Abstract
【解決手段】 金属水銀を含む排ガスを、酸化チタンを第一成分、ニッケル(Ni)、マンガン(Mn)もしくはバナジウムの硫酸塩、またはリン酸塩を第二成分とする触媒に、100℃以上、200℃以下で接触させ、前記金属水銀を酸化する排ガスの浄化方法。
【選択図】 図1
Description
(1)イオウ酸化物および金属水銀を含む排ガスを、酸化チタンを第一成分、ニッケル(Ni)、マンガン(Mn)もしくはバナジウムの硫酸塩、またはリン酸塩を第二成分とする触媒に、100℃以上、200℃以下で接触させ、前記金属水銀を酸化することを特徴とする排ガスの浄化方法。
(2)酸化チタンを第一成分、ニッケル(Ni)、マンガン(Mn)もしくはバナジウムの硫酸塩、またはリン酸塩を第二成分として含有する、排ガス中の金属水銀の酸化触媒。
(3)乾燥または焼成による最大履歴温度が300℃以下であることを特徴とする(2)に記載の触媒。
(4)モリブデン(Mo)またはタングステン(W)のオキソ酸もしくはオキソ酸塩を第三成分としてさらに含有することを特徴とする(2)または(3)に記載の触媒。
(1)低温におけるSO2の酸化は、下記の酸素による酸化反応(1式)ではなく、(2式)のNOとの反応が中心である。(1式)の酸化反応は300℃以上で優勢である。
SO2+1/2O2 → SO3 (1式)
2NO+SO2 → N2O+SO3 (2式)
(2)酸化チタンは(2式)の反応の優れた触媒になる。
(3)SO2による触媒の劣化は、触媒活性成分の硫酸塩化に伴う体積増加と、(2式)の反応で生成したSO3が硫酸または酸性硫酸塩類として触媒の細孔を閉塞させることにより引き起こされる。脱硝装置やEPで注入されたアンモニアが残存する場合には、酸性硫酸アンモニウムとして細孔を閉塞し、劣化を加速する。
本発明は、上記知見を基になされたもので、下記の作用効果を有する。
(b)最高熱履歴温度を300℃以下に制限することにより、硫酸塩またはリン酸塩が触媒の酸化チタンと反応して分解することを防ぎ、使用段階で硫酸塩化して体積増加する現象を低減した。
(c)SO2の酸化(2式)が酸化チタンにより促進されることを避けるため、活性成分の硫酸塩/リン酸塩に加え、酸化チタンに吸着されやすいMo、Wのオキソ酸イオンを含む化合物を添加して酸化チタン表面を覆い、(2式)による酸化を抑制した。
以下、本発明を具体例を用いて詳細に説明する。
硫酸ニッケル(NiSO4・6H2O)223gをシリカゾル(日産化学社製、o-ゾル、SiO2含有量20重量%) 412gに溶解後、酸化チタン(石原産業社製、比表面積290m2/g)900gを添加後、混練機により混合した。途中水を約200g添加して粘稠なペーストにした後、無機繊維(カオリン系、ニチアス社製)を155g添加して硬いペーストを得た。このペーストを厚さ0.2mmのSUS430製鋼板をメタルラス加工した厚さ0.7mmの基材の上にき、これを二枚のポリエチレンシートに挟んで一対の加圧ローラを通して、該メタルラス基材の網目を埋めるように塗布した。得られた板状触媒は、120℃乾燥後、150℃で2時間焼成した。
実施例1に用いた硫酸ニッケルを硫酸マンガン(MnSO4・5H2O)204gに代える以外は実施例1と同様にして触媒を得た。
[実施例3]
実施例1に用いた硫酸ニッケルを硫酸バナジル(VSO4・xH2O、VOSO4含有量72.2%)を191gに代える以外は実施例1と同様にして触媒を得た。
[実施例4]
硝酸ニッケル(Ni(NO3)2・6H2O)246g、85%リン酸98gとを練り合わせて反応させた後、シリカゾル(日産化学社製、o-ゾル、SiO2含有量20重量%)を422gを加えてスラリ状にし、これに酸化チタン(ミレニアム社製G5、比表面積300m2/g)を添加、水を200g添加しながら混練、さらに無機繊維158g添加して混練した。このペーストを厚さ0.2mmのSUS430製鋼板をメタルラス加工した厚さ0.7mmの基材の上にき、これを二枚のポリエチレンシートに挟んで一対の加圧ローラを通して、該メタルラス基材の網目を埋めるように塗布した。得られた板状触媒は、120℃乾燥後、200℃で2時間焼成した。
実施例4に用いた硝酸ニッケルを硝酸マンガン(Mn(NO3)2・6H2O) 243gに代える以外は実施例4と同様にして触媒を調製した。
[実施例6]
実施例4に用いた硝酸ニッケルを五酸化バナジウム(V2O5)77gと水150gの混合物に代える以外は実施例4と同様にして触媒を調製した。
[実施例7〜10]
実施例3ないし6に用いた触媒について、焼成温度をそれぞれ300℃(実施例7)、500℃(実施例8)、300℃(実施例9)および500℃(実施例10)に代える以外は同様にして触媒を得た。
実施例3において硫酸バナジルの添加に加えて、メタタングステン酸アンモニウム(WO3含有量93%)を121g添加し、他は実施例3と同様にして触媒を調製した。
[実施例12]
実施例6において五酸化バナジウムの添加に加えて、モリブデン酸アンモニウムを139g添加して混練すると共に、焼成温度を300℃に変更する以外は同様にして触媒を調製した。
実施例1において硫酸ニッケル、実施例4において硝酸ニッケルとリン酸をそれぞれ添加せず、第一成分である酸化チタンのみの触媒を調製した。
[比較例3〜5]
実施例4〜6においてリン酸を添加せず、500℃、2時間焼成する以外は同様にしてそれぞれ触媒を調製した。
[反応例1]
実施例1〜12、及び比較例1〜5で得た触媒をそれぞれ100mm×20mmの短冊状に切り出し、(1式)の反応で生成するSO3が細孔内に蓄積して劣化する速度を把握するため、表1の条件で発生するN2Oの生成量を各触媒の劣化速度の指標として測定した。また表2の条件で各触媒の金属水銀のHg酸化率を測定した。得られた結果を表3と表4に纏めて示した。
