Description
例えば、Zr含有量が7.40重量%である触媒担体10g(10gのZrO2 に対応する)は、酢酸で処理される。Zr0.074gは、前記溶出液で検出される。Zrの放出は、(0.074 g*(123.223)/91.224))/10 g = 0.1%として計算される。
硬度(ディメンジョン(dimension)):N
試料からの距離:5.00mm
遅延時間:0.80s
フィードタイプ:6D
速度:0.06mm/s
(水負荷後の重量(g)−水負荷前の重量(g))×10 = 吸水度(%)
ZrO2 の収率 = 鉱酸処理後の触媒担体における(ZrO2 に変質した)Zr含有量×得られた触媒担体の量/使用された(ZrO2 に変質した)Zrの量
本発明に係る方法によって作製された触媒担体のZrO2 の収率は、少なくとも85%、好ましくは少なくとも95%、より好ましくは少なくとも97%に達する。
層状ケイ酸塩として主な構成物質モンモリロナイトを有し且つ酸で処理され且つ乾燥された粉末状のベントナイト(酸で活性化されたベントナイト)500gは、約1μmのd10値、約5μmのd50値、約7μmのd90値を有する、ZrO2 61.875gに対応する量の市販のZr(OH)4 と、有機結合剤/孔形成薬10gとに混合された。
触媒担体は、ZrO2 132gに対応した市販のZr(OH)4 の量が使用されたこと以外は、例1と同様に作製された。このようにして得られた成形体は、表1aに示される特徴を有する。
触媒担体は、前記触媒担体が8時間だけ塩酸で処理されたこと以外は例1と同様に作製された。このようにして得られた成形体は、表1bに示される選ばれた特徴を有する。
触媒担体は、成形後に550℃だけで第1焼成が実施されたこと以外は同様に作製された。このようにして得られた成形体は、表2に示される選ばれた特徴を有する。
商標名が「KA−160」であり、ズード−ケミー アーゲー(ミュンヘン、ドイツ)から販売されている触媒担体は、表3に示される特徴を有する。
(US 5,808,136を参照。)Zr含有量が15.5重量%である酢酸ジルコニウム(ZrO(OAc)2 )の水溶液74.6gは、水約8.5mLで希釈された。例3に係るズード−ケミー アーゲー製の100gの触媒担体KA−160が、上記溶液に含浸された。含浸された担体は、乾燥され、500℃で焼成された。得られた触媒担体は、ジルコニウム含有量が約10重量%である(13.53重量%のZrO2 に対応しているとして計算される。)。前記触媒のさらなる特徴は、表4に示される。
触媒担体は、20%硝酸ジルコニル溶液57.8gを水19.7mLで希釈したものが使用されたこと以外は例1と同様にして作製された。このようにして得られた担体の特徴は、表5に示される。
表6では、例3、4、1及び1aの平均孔径、総細孔容積、前記総細孔容積における特定の孔径の割合が対比される。
