Description
a)アルミナに対するシリカの比として4.5から6.5の比及び1.5重量%未満のアルカリ濃度を有するフォージャサイト構造の出発ゼオライトを準備するステップ、
b)前記出発ゼオライトを、600から850℃まで、好ましくは600〜700℃、より好ましくは620〜680℃、特に630〜670℃の範囲の温度と、好ましくは外部から供給される0.2から1気圧までの範囲の水蒸気の分圧とで、24.30から24.45Åまでの単位胞の大きさを有する中間体ゼオライトを生じさせるのに有効な時間(適切には0.5から5時間まで、より適切には1〜3時間である)熱水的に処理するステップ、
c)前記中間体ゼオライトを、酸及び場合によってアンモニウム塩を含む酸性化した溶液と、24.10から24.40Åまでの範囲の単位セルの大きさ、13を超えるバルクのシリカ対アルミナのモル比及び少なくとも875m2/gの表面積を有する高表面積ゼオライトを生じさせるのに有効な条件下で接触させ、それによって前記高表面積ゼオライトを生じさせるステップ、及び
d)前記高表面積ゼオライトを回収するステップ。
20から100まで、好ましくは20から80まで、特に50までの範囲のSAR、
少なくとも890、具体的には少なくとも910m2/gの表面積、
0.28ml/gを超え、適切には0.30ml/gを超える、Lippens、Linsen及びde Boer、Journal of Catalysis、3−32、(1964)に記載されている吸着質として窒素を使用するt−法としても知られるt−プロット法を用いる窒素ポロシメトリーによって測定されるミクロ細孔容積。一般に、ミクロ細孔容積は、0.40ml/g未満、適切には0.35ml/g未満である。ここでのミクロ細孔は、2nm未満の直径を有する細孔である。
単位セルの大きさ:ASTM D−3942−80の方法を用いるX線回折によって測定。
表面積:文献、S.Brunauer、P.Emmett及びE.Teller、J.Am.Chm.Soc,60、309(1938)及びASTM法D4365−95に記載されている標準的なBET(Brunauer−Emmett−Teller)法の窒素吸着技術に従って測定。下に示した測定において、その結果は、高温の前処理に続く0.03の窒素分圧においてとられたシングルポイント評価として与えられている(下の注も参照)。
アルミナに対するシリカのモル比(SAR):化学分析によって測定、示されている値は、「バルク」のSAR(即ち、全体のSAR)であり、具体的に言うと結晶骨格のSARではない。
触媒中に利用されている本発明のゼオライトYは、WO2004/047988の教示に従って調製した。使用した出発材料は、低アルカリ含量(1.5重量%の酸化アルカリ未満)アンモニウムの形のYゼオライトである。これらのゼオライトは、当技術分野で知られている2つの方法の1つによって調製した。同様の結果を得るその他の方法を排除するつもりはないが、本発明の実施例は、Na型ゼオライトYのK+イオン交換を含み、続いてアンモニウムイオン交換があるCooper法(米国特許第5,435,987号明細書に記載されている)か、又は自己超大気圧下でのアンモニウム交換を含むAlafandi法(米国特許第4,085,069号明細書に記載されている)のいずれかによって調製した。この低アルカリ含量アンモニウム型Yゼオライトは、超安定なタイプのYゼオライトを創り出すために1つ又は2つのステップで水蒸気焼成した。その水蒸気加熱したゼオライトを次に塩化アンモニウムと塩酸との組合せによる1ステップの処理からなる酸脱アルミニウム処理(acid de alumination treatment)にかけた。そのイオン交換脱アルミニウム処理における水含有量は、5から25%までの無水ゼオライトを有するゼオライトスラリーを提供するには概ね十分であった。そのような変動は、得られる結果に実質的に影響を及ぼすとは考えられない。
更に、上記触媒担体のIRスペクトルを、水銀カドミウムテルル検出器を用いるBiorad FTS175 FT−IRスペクトロメーターを用いて測定した。セルに10個の位置を含む試料保持器を装備し、試料は、25.3±0.1mgのゼオライト粉末から3.5〜4トンの圧力でプレスした18mmの直径を有する自己支持ウエハーとして測定した。バックグラウンド測定については試料保持器の開放位置を使用した。バックグラウンド及び試料のスペクトルは、2cm−1の分解能で250のスキャンを集めることによって測定した。スペクトロメーターは、水蒸気の妨害を最小限にするために窒素によりフラッシュする。試料は、5×10−4ミリバールより下まで排気した後、特別の加熱帯中そのままの状態で、10℃/分の割合で450℃まで上昇させ、保持時間が450℃で30分間である温度プログラムを適用することによって活性化した。その後、試料は20℃/分で50℃まで冷却した。次いでバックグラウンド及び試料のIRスペクトルを測定した。
上記スペクトルを記録した後、試料保持器を加熱帯に戻し、50℃でさらに15分間、真空を維持しながら平衡状態にさせた。H/D交換は、そのままの状態で、8〜9トールのヘキサジュウテロベンゼン(C6D6)を活性化したゼオライト試料と50℃で15分間相互作用させ、続いて45分間にわたって5×10−4ミリバールの目標圧力まで(最大で1時間)排気することによって実施した。次いでバックグラウンド及び試料のIRスペクトルを測定した。
結晶化度は、XRDによって測定されるピークの広がりの変化を追うことにより高度に結晶性のVUSYの対照と比較することによって測定される。
