Abstract
【解決手段】 本発明のフィルタ触媒は、触媒担体基材と、触媒層と、を有するフィルタ触媒において、1〜20μmの細孔を11%以上の気孔率で有することを特徴とする。本発明のフィルタ触媒は、十分なパティキュレートが堆積したときの圧損の上昇を抑えることができる効果を有する。
【選択図】 なし
Description
まず、アルミナ(Al2O3)粉末150g、水200gを秤量し、アルミナ粉末を水に投入、攪拌して分散させ、湿式ミリングを施してスラリーを調製した。アルミナ粉末全体を100wt%としたときに、1μm以下の粒径の粒子が77%となっていた。
スラリーのアルミナをチタニア(TiO2)のみで形成した以外は、実施例1と同様にして本実施例のフィルタ触媒を製造した。
スラリーのアルミナのコート量を75gとした以外は、実施例1と同様にして本実施例のフィルタ触媒を製造した。
アルミナ粉末150g、水200gを秤量し、アルミナ粉末を水に投入、攪拌して分散させ、湿式ミリングを施してスラリーを調製した。アルミナ粉末全体を100wt%としたときに、1μm以下の粒径の粒子が77%となっていた。
アルミナ粉末150g、水200gを秤量し、アルミナ粉末を水に投入、攪拌して分散させ、湿式ミリングを施してスラリーを調製した。アルミナ粉末全体を100wt%としたときに、1μm以下の粒径の粒子が10%となっていた。
アルミナ粉末75g、水200gを秤量し、アルミナ粉末を水に投入、攪拌して分散させ、湿式ミリングを施してスラリーを調製した。アルミナ粉末全体を100wt%としたときに、1μm以下の粒径の粒子が77%となっていた。
実施例および比較例のフィルタ触媒の細孔構造を水銀ポロシメータ(島津製作所製、商品名:オートポアー9200)を用いて測定した。測定結果を表1に示した。なお、細孔構造の測定における水銀ポロシメータの操作は、0〜200MPaの間で水銀圧入圧力を上昇させていくことで行われた。
つづいて、実施例および比較例のフィルタ触媒の圧損の測定を行った。
