Abstract
Description
図1は、開示された方法を実施するために用いることができる装置を概略図示する説明図である。
図3は、モリブデン含浸モルデナイト触媒を用いるC9芳香族の定常状態転化のプロセスフローを概略図示する説明図である。
本発明は、一般に、パラキシレン製造用の化学供給原料として特に適するキシレン異性体類の製造方法に関する。特に、本方法は、C9芳香族含供給物をキシレン異性体類含有中間生成物流に転化するに適する条件下で、C9芳香族含有供給物を触媒と接触させ、中間生成物流からキシレン異性体類の少なくとも一部を分離し、貧キシレン異性体類中間生成物流を供給物に再循環させることを含む。あるいは、キシレン異性体類の製造方法は、C9芳香族とベンゼンを含む供給物をキシレン異性体類含有生成物流に転化するに適する条件下で、供給物の総量を基準として約30 wt.%未満のベンゼンとC9芳香族とを含む供給物をVIB族金属酸化物含浸非硫化ラージポアゼオライトと接触させることを含む。
本実施例は、2種の触媒(触媒A及びB)の調製を記載する。これら触媒は、続いて実施例2〜4に記載するプロセスで用いた。第1の触媒である「触媒A」はモルデナイトゼオライトであり、第2の触媒である「触媒B」はモリブデン含浸モルデナイトゼオライトを含む。本実施例は、さらに、他の2種の触媒(触媒C及びD)の調製をも記載する。これらの触媒は、続いて実施例5に記載するプロセスで用いた。「触媒C」は、モリブデン含浸β型ゼオライトからなり、一方、「触媒D」はモリブデン含浸 USY型ゼオライトからなる。
本実施例は、ニトロ化級(nitration-grade)トルエンをベンゼン及びキシレンに転化するためのモルデナイト触媒(実施例1の「触媒A」)及びモリブデンを含浸した同一の触媒(実施例1の「触媒B」)のパフォーマンス・ケイパビリティを説明する。各実験において、破砕した触媒を3/4インチ管状ステンレススチール栓流反応器に充填し、液体供給物の導入前に、2時間かけて、400℃(752゜F)で200psig(約1.4MPa)で水素を流しながら処理した。供給物流は水素とトルエン(水素:トルエンモル比が4:1)の混合物であり、反応条件は400℃(752゜F)で200 psig(約1.4 MPa)であり、WHSVは触媒Aについて1.0及び2.0、触媒Bについて1.0、2.0及び5.0であった。各実験で得られた液体供給物(Feed Wt.%)及び生成物(Pdt. Wt.%)の分析結果はTable 1に示す。
本実施例は、ほぼ100%のC9芳香族含有供給物をキシレン異性体類に転化するためのモルデナイト触媒(実施例1の触媒A)及びモリブデンが含浸された同一の触媒(実施例1の触媒B)のパフォーマンス・ケイパビリティを説明する。供給物の組成は下記Table 2に示し、5回の実験の各々で同一であった。各実験において、触媒を3/4インチ管状ステンレススチール栓流反応器に充填して、液体供給物の導入前に、2時間にわたり、400℃(752゜F)で200 psig(約1.4 MPa)で水素を流しながら処理した。供給物流は、 モル比が4:1の水素及び炭化水素の混合物であった。反応条件は、400℃(752゜F)、200 psig(約1.4 MPa)であった。触媒Aを用いる2種の実験についてのWHSVは1.0及び1.5であり、一方、触媒Bを用いる3種の実験についてのWHSVは1.0、1.5及び2.0であった。液体供給物及び各実験で得られた生成物の分析結果は下記Table 2に示す。
前述の実施例は、単一工程(single pass)で得られ得る転化を示す。再循環を用いる定常状態プロセスで得られ得る転化率を決定又は推定することも可能である。触媒Aを用いるプロセスでの再循環収率は、上記Table 2に示した結果に基づいてプロセスをモデル化することによって決定した。このモデル化に基づくプロセスフローダイアグラムを図2に示す。
1.49 lbmoles x (0.26 + 0.36) ÷ 2 = 0.462 Ibmoles.
同様に、ベンジル基のキシレンポテンシャルは、ベンジル基のモル量を生成物中BTXに対する供給物中芳香族環の選択率と掛け合わせることにより決定される。
0.822 Ibmoles x 0.69 = 0.567 Ibmoles.
上述の内容に基づいて、メチル基の利用可能性はキシレン類の製造を制限するといえる。これに基づいて、モル基準での再循環収率は、0.462 Ibmoles キシレン類;0.105 Ibmoles ベンゼン(0.567と0.462との差);0.082 Ibmoles エチルベンゼン;0.173 Ibmoles C10+重質質芳香族と計算される。軽質非芳香族を含む相対質量基準では、9% 軽質非芳香族;8% ベンゼン;49% キシレン類;9% エチルベンゼン;25% C10+重質芳香族となる。
触媒Bを用いる定常状態プロセスでの再循環収率は、上記Table 2に示す結果に基づいてプロセスをモデル化することにより同様に決定される。このモデル化に基づくプロセスフローダイアグラムを図3に示す。図3は、異なる転化率が得られ得る点を除いて図2に示したモデル化と多数の類似点を有する。
本実施例は、モルデナイト触媒(実施例1の触媒A)とモリブデンを含浸した同じ触媒(実施例1の触媒B)の約61 wt% C9芳香族(A9)炭化水素類及び約38 wt%トルエンを含む供給物をキシレン異性体類へ転化するパフォーマンス・ケイパビリティを説明する。2種の別個の実験を同じ供給物で行った。各実験において、触媒を3/4インチ管状ステンレススチール栓流反応器に充填し、液体供給物の導入前に、水素を流しながら2時間400℃(752゜F)、200 psig(約1.4 MPa)で処理した。供給物流は、水素及び炭化水素の4:1モル比の混合物であった。反応条件は、400℃(752゜F)、200 psig(約1.4 MPa)、WHSV 1.0に設定した。液体供給物及び生成物の分析結果を下記Table 5に示す。
本実施例は、ラージポアモリブデン含浸ゼオライト触媒のパフォーマンス・ケイパビリティを説明する。特に、本実施例は、モリブデン含浸モルデナイト触媒(実施例1の触媒B)、モリブデン含浸β型ゼオライト(実施例1の触媒C)及びモリブデン含浸USYゼオライト(実施例1の触媒D)について、約60 wt% C9芳香族(A9)炭化水素及び約38 wt%トルエンを含む供給物をキシレン異性体類に転化するためのパフォーマンス・ケイパビリティを説明する。同じ供給物について4種の別個の実験を行った。各実験において、触媒を3/4インチ管状ステンレススチール栓流反応器に充填し、液体供給物の導入前に、水素を流しながら2時間、約400℃(752 ゜F)(下記に示したデータにおいて特にことわらない限り)及び200 psig(約1.4 MPa)で処理した。供給物流は、水素及び炭化水素の4:1モル比混合物であり、反応条件は400℃(752゜F)(特にことわらない限り)、200 psig(約1.4 MPa)、WHSV 1.0に設定した。液体供給物及び生成物の分析結果は、下記Table 6に示す。
