Abstract
【解決手段】 酸化チタンと、酸化チタンに対し1を越えて15重量%以下のリン酸またはリン酸アンモニウム塩とを水の存在下で接触させ、表面にリン酸イオンを吸着させた酸化チタンに、モリブデン(Mo)及び/またはタングステン(W)のオキソ酸もしくはオキソ酸塩と、バナジウム(V)のオキソ酸塩もしくはバナジル塩とを、0を越えて8原子%以下で担持した排ガスの浄化用触媒。
【選択図】なし
Description
(1)酸化チタンと、酸化チタンに対しH3PO4として1を越えて15重量%以下のリン酸またはリン酸アンモニウム塩とを水の存在下で接触させ、表面にリン酸イオンを吸着させた酸化チタンに、モリブデン(Mo)及び/またはタングステン(W)のオキソ酸もしくはオキソ酸塩と、バナジウム(V)のオキソ酸塩もしくはバナジル塩とを、0を越えて8原子%以下で担持したことを特徴とする排ガスの浄化用触媒。
(2)バイオマス専焼、またはこれと化石燃料とを混焼した排ガスに、還元剤としてNH3を吹き込み後、(1)記載の触媒と接触させ、排ガス中に含まれる窒素酸化物を還元除去することを特徴とする排ガスの浄化方法。
NH3+HO-Ti-(TiO2上の活性点) → NH4-O-Ti- (式1)
1/2K2CO3+HO-Ti-(TiO2上の活性点) → K-O-Ti- +1/2H2O+1/2CO2 (式2)
H3PO4+3(HO-Ti-) → PO4(-Ti-)3+3/2H2O (式3)
3/2K2CO3+PO4(-Ti-)3+3/2H2O → K3PO4+3(HO-Ti-) (式4)
本願発明の触媒において、これら活性成分の添加方法はどのような方法でもあってもよいが、水の存在下で混練または加熱混練する方法が経済的であり、優れている。さらに活性成分担持後の触媒成分は、公知の方法によりハニカム状に成形して用いられる他、網状に加工した金属基板やセラミック繊維の網状物に目を埋めるように塗布して板状化した後、波型などにスペーサ部を成形したものを積層し、触媒構造体として触媒装置に用いることができる。特に後者はカリウム化合物を含む灰が触媒間に堆積しにくいので好結果を与え易い。
[実施例1]
酸化チタン(石原産業社製、比表面積290m2/g)900g、85%リン酸84.5g、シリカゾル(日産化学社製,OSゾル)219g及び水5568gをニーダに入れて45分間混練し、リン酸をTiO2表面に吸着させた。これにモリブデン酸アンモニウム113g及びメタバナジン酸アンモニウム105gを添加して更に1時間混練し、リン酸を吸着したTiO2表面にMoとVの化合物を担持させた。その後、シリカアルミナ系セラミック繊維(東芝ファインフレックス社製)を151gを徐々に添加しながら、30分間混練して均一なペースト状物を得た。得られたペーストを、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、メタルラス基材の網目を埋めるように塗布した。これを風乾後、500℃で2時間焼成して本願発明の触媒を得た。この触媒の組成はTi/Mo/V=88/5/7原子比であり、H3PO4添加量はTiO2に対し8重量%である。
実施例1において、リン酸添加量をそれぞれ84.5gを10.6g及び42.4gに変える以外は同様にして触媒を調製した。
[実施例4]
実施例1において、リン酸の添加量を159g、メタバナジン酸アンモニウムの添加量を121gにそれぞれ変更する以外は同様にして触媒を調製した。本触媒の組成はTi/Mo/V=88/5/8原子比でありH3PO4添加量はTiO2に対し15重量%である。
実施例1に用いた酸化チタンを比表面積90m2/gの酸化チタンに変更し、リン酸の添加量をTiO2に対し4重量%に変え、さらにメタバナジン酸アンモニウムとモリブデン酸アンモニウムとを、6.8gと61.8g、及び27.7gと62.7gとにそれぞれ変更する以外は実施例1と同様にして触媒を調製した。本触媒の組成はTi/Mo/V=96.5/3/0.5原子比、及び95/3/2原子比、H3PO4添加量はTiO2に対し4重量%である。
[実施例7]
実施例1の触媒に用いたモリブデン酸アンモニウム113gをメタタングステン酸アンモニウム162gに変える以外は実施例1と同様にして触媒を調製した。本触媒の組成はTi/W/V=88/5/7原子比であり、H3PO4添加量はTiO2に対し8重量%である。
実施例1、5〜7において、リン酸の添加及び吸着処理を行わない以外は同様にして触媒を調製した。

実施例1〜7及び比較例1〜4の触媒を20mm幅×100mm長さに切り出し、バイオマス燃焼灰中に含まれるカリウム化合物による劣化を模擬するため、これに炭酸カリウムの水溶液を触媒成分に対しK2Oとして0.5重量%の添加量になるように含浸後、150℃で乾燥した。
Claims (2)
- 酸化チタンと、酸化チタンに対しH3PO4として1を越えて15重量%以下のリン酸またはリン酸アンモニウム塩とを水の存在下で接触させ、表面にリン酸イオンを吸着させた酸化チタンに、モリブデン(Mo)及び/またはタングステン(W)のオキソ酸もしくはオキソ酸塩と、バナジウム(V)のオキソ酸塩もしくはバナジル塩とを、0を越えて8原子%以下で担持したことを特徴とする排ガスの浄化用触媒。
- バイオマス専焼、またはこれと化石燃料とを混焼した排ガスに、還元剤としてNH3を吹き込み後、請求項1記載の触媒と接触させ、排ガス中に含まれる窒素酸化物を還元除去することを特徴とする排ガスの浄化方法。
