Description
オフガスまたは排ガスをセラミックキャンドルフィルタに通し及び粒状物を捕集するステップ、
フィルタの壁上に及び/または壁内に配置されている酸化触媒と接触させることによって、フィルタの分散側に捕集された粒状物中の煤の量を減少させ及びオフガスまたは排ガス中の炭化水素の量を減少させるステップ、
を含み、
ここで前記酸化触媒は、フィルタの20ppm/重量と1000ppm/重量との間の全量で一種以上の貴金属を含む、
前記方法を提供する。
酸化バナジウム(II)(一酸化バナジウム)、VO;または
酸化バナジウム(III)(三二酸化バナジウムまたは三酸化バナジウム)、V2O3; または
酸化バナジウム(IV)(二酸化バナジウム)、VO2;または
酸化バナジウム(V)(五酸化バナジウム)、V2O5;
のことを指す。
白金またはパラジウムの触媒活性形態はその金属及び/または酸化物形態である。
以下の例は、長さ3m及び壁厚20mmのカルシウム−マグネシウム−シリケート繊維から製造されたセラミックキャンドルフィルタを用いて得ることができる性能を例証するものである。フィルタは、その壁内において、フィルタの全重量に基づいて計算して1.26重量%のV及び2.36重量%のTiを含むV/Ti触媒でコーティングした。コーティングされたフィルタの多孔度は83%であった。このフィルタを、40ppmの無水トルエン、19体積%のO2、8体積%のH2Oを含む入口ガス中でのトルエンの酸化について試験した。
以下の例は、追加的に36ppmのPdでコーティングされた、例1のセラミックキャンドルフィルタのCO酸化性能を例証するものである。これらの試験は、約150ppmの湿性CO、19%のO2及び8%のH2Oを含むガスを用いて行った。
本願は特許請求の範囲に記載の発明に係るものであるが、本願の開示は以下も包含する:
1.
