Description
N.Y.ChenおよびW.E.Garwood、Catl.Rev.Sci.Eng.、28巻(1986年)、185頁 K.TanabeおよびW.Hoelderich、Appl.Catal.A:General、181巻(1999年)、399頁
従来型ZSM−5の調製
Al2O3が1、TPA2Oが9、Na2Oが1.25、SiO2が50、H2Oが385のモル組成を有するゲルの結晶化によって従来型ZSM−5ゼオライトを調製した。このゲルは、テトラプロピルアンモニウムヒドロキシド水溶液(147g、40wt%)を水(22g)に添加し、続いてこの混合物に撹拌しながらアルミン酸ナトリウム(3.00g、NaAlO2、54wt%Al2O3、41wt%Na2O)を添加して得た。アルミン酸ナトリウムが溶解するまで撹拌を続け、その後、オルトケイ酸テトラエチル(166g、Si(OCH2CH3)4、99%)を添加した。
例2
メソ細孔性ZSM−5の製造
40gのカーボンブラック(Carbot Corp.社が供給するBlack Pearls2000)を130℃で12時間乾燥することによってメソ細孔性ZSM−5ゼオライトを製造した。この冷却したカーボンブラックにテトラプロピルアンモニウムヒドロキシド(40wt%、73.5g)、アルミン酸ナトリウム(NaAlO2、54wt%Al2O3、41wt%Na2O、0.75g)、水(11g)およびエタノール(65g)からなる澄明溶液を含浸させた。エタノールを蒸発させた後、このカーボンブラックに、カーボンブラックの初期湿潤状態の含浸(incipient wetness impregnation)をもたらすに相当する量のオルトケイ酸テトラエチル(99%、Si(OCH2CH3)4、83g)を含浸した。得られた合成ゲルの組成は、Al2O3が1、TPA2Oが20、Na2Oが1、SiO2が100、H2Oが200、EtOHが200であった。
例3
メタ−キシレンの異性化
実施例1および実施例2のH−ZSM−5触媒をペレットにして、粉砕し、150〜300マイクロメートルの範囲の大きさの粒子を分別し、そしてこれを使用してメタ−キシレンの異性化を実施した。
例4
実施例1および実施例2のH−ZSM−5触媒をペレット化し、粉砕し、そして150〜300マイクロメートルの範囲の大きさの粒子を分別し、これを使用してメタ−キシレンの異性化ならびに供給物中に存在するエチルベンゼンの転化を実施した。
