Abstract
Description
カチオン性高分子電解質をカオリンスラリーに添加し、その後で後続のゼオライト成長のための微小球基材へと加工することによって、改善された耐摩損性がインサイチュ形成(その場で形成された)FCC触媒にもたらされる。
本発明の微小球触媒は、本発明の譲受人に譲渡された米国特許第4,493,902号明細書に開示された包括的方法によって製造される。本発明の触媒のアルミナリッチな非ゼオライトマトリックスが超微細粉末の形態である含水カオリン供給源から誘導され、ここで前述の米国特許第6,943,132号明細書に開示されるように、この超微細粉末の少なくとも90質量%が2.0マイクロメートル未満であり、好ましくは少なくとも70質量%が1マイクロメートル未満であることは、必須ではないが好ましい。この超微細含水カオリンは、微粉砕され、かつ発熱を経て焼成される。ゼオライト微小球が、より大きなサイズを有するカオリンから誘導されるアルミナリッチなマトリックスを用いて形成され、かつ少なくとも実質的にその特徴的な発熱を経て焼成されることも、本発明の範囲内である。Satintone(登録商標)No.1(ムライトが実質的に全く生成されることなくその特徴的な発熱を経て焼成された市販のカオリン)は、アルミナリッチなマトリックスを形成するために商業ベースで用いられる材料である。Satintone(登録商標)No.1は、粒子の70%が2マイクロメートル未満である含水カオリンから誘導される。アルミナリッチなマトリックスを形成するために用いられる他の供給源には、少なくとも実質的にその特徴的な発熱を経て焼成された微細含水カオリン[例えばASP(登録商標)600、すなわち“Aluminum Silicate Pigments”(EC-1167)と題するEngelhard社の技術告示No. TI-1004に記載されている市販の含水カオリン]が含まれる。ブックレットクレーが最も広範に商業的に用いられており、世界規模で多大な成功を収めている。
37.5乾燥質量%の含水カオリンおよび62.5乾燥質量%の焼成カオリンからなる含水および焼成カオリンスラリーをブレンドして全スラリー固体水準を約50質量%にすることにより、本発明による試料を生成した。この含水および焼成カオリン成分に関する注目すべき物理的特性を、第1表および第2表に列挙した。+325メッシュ残渣は、325メッシュスクリーン(スクリーンメッシュ間の間隔が44μm)を通過しない粗い材料である。1μm未満の%および2μm未満の%の分類は、Sedigraph 5200により測定された球相当径が1または2μm未満である粒子の質量%である。この焼成カオリンは、約950℃で開始してしばしばスピネル相またはムライト相と呼ばれる形態またはこれら2つの相の組み合せを形成する特徴的な発熱転移を経て加熱された材料からなる。ムライト指数(MI)は、100%ムライト参照試料に対するこのカオリン試料中のムライトピークの比であり、この比は焼成カオリンへの熱処理の程度を示す。見かけ嵩密度(ABD)は、空隙率を含む材料の単位体積あたりの質量である。タップ嵩密度(TBD)は、TAP-PACK Volumeter(ISO 787−11)を用いて測定された、より効率的な粒子充填を促進するための作業を行った後の嵩密度の程度である。
Superfloc C577の供給量を変化させて、またはその他のカチオン性高分子電解質薬剤を添加して本発明の微小球を製造するために、同一の含水および焼成カオリン成分を利用した。ポリアミン添加を、実施例1と同様に、バインダー供給量を減少させてケイ酸ナトリウムとして4質量%のSiO2を用いて行った。「対照標準」と表示されている比較試料を、噴霧乾燥前に添加されるケイ酸ナトリウムとして8質量%のSiO2を用いて形成した。第5A表および第5B表に、処理して完成触媒とするために各々の微小球試料の結晶化に利用した配合を示す。
