Abstract
Description
ナノサイズのゼオライトを形成するために、ヒュームドシリカ(AEROSIL(登録商標)200、エボニックインダストリーズより入手可能)、アルミニウム粉末、およびテトラエチル水酸化アンモニウム(TEAOH)(35wt%水溶液、アルドリッチより入手可能)を、それぞれ、シリカ供給源、アルミニウム供給源、およびテンプレート剤として使用した。前駆体ゲルは、30TEAOH:50SiO2:Al2O3:750H2Oの酸化物モル組成比を有していた。金属アルミニウムを、TEAOH含有水溶液の一部に溶解して透明な溶液を作り、次に、ヒュームドシリカおよびTEAOH含有水溶液の他の部分により作製したスラリーに加えた。形成したアルミノケイ酸塩流体ゲルを、ビーカー内で周囲温度にて4時間撹拌し、次に、125ミリリットル(mL)のポリテトラフルオロエチレン(PTFE)で線を引いたステンレス・スティールのオートクレーブに移した。結晶化を、413ケルビン(K)にて、オーブン内での静止状態下、またはオイルバス中60rpmでの回転状態下のいずれかで生じさせた。様々な結晶化期間の後、オートクレーブをクエンチして結晶化プロセスを停止させた。
従来のナノサイズのゼオライト触媒を、以下のプロセスにより調製した。ヒュームドシリカ(AEROSIL(登録商標)200、エボニックインダストリーズより入手可能)、アルミニウム粉末、およびTEAOH(35wt%水溶液、アルドリッチより入手可能)を、それぞれ、シリカ供給源、アルミニウム供給源、およびテンプレート剤として使用した。前駆体ゲルは、酸化物モル組成30TEAOH:50SiO2:Al2O3:750H2Oを有していた。金属アルミニウムを、TEAOH含有水溶液の一部に溶解して透明な溶液を作り、次に、ヒュームドシリカおよびTEAOH含有水溶液の他の部分により作製したスラリーに加えた。形成したアルミノケイ酸塩流体ゲルを、ビーカー内で周囲温度にて4時間撹拌し、次に、125mLのPTFEで線を引いたステンレス・スティールのオートクレーブに移した。結晶化を、413Kにて、オーブン内での静止状態下、またはオイルバス中での回転状態(60rpm)下のいずれかで生じさせた。様々な結晶化期間の後、オートクレーブをクエンチして結晶化プロセスを停止させた。最終生成物を、液体から16,000rpmの遠心分離を使用して分離し、pH<9.0まで脱イオン水で数回洗浄し、383Kにてオーブン内で乾燥させた。
により決定した。実施例1および実施例2の触媒についての触媒活性試験の結果を、表3において示す。
