Description
本発明の方法で使用される分解触媒成分は、顕著な活性を備えた所望の種類のどのような触媒でもよい。好ましくは、ここで使用される触媒は、結晶性アルミノケイ酸塩を含む触媒であり、好ましくは、アンモニア交換され、少なくとも部分的に希土類金属カチオンと交換されたものであり、しばしば、「希土類−交換結晶性ケイ酸アルミニウム」、例えば、REY、CREY又はREUSY、又は、安定化アンモニウム又は水素ゼオライトの1種とされるものである。
本発明の金属不動態化剤/捕捉剤は、軽油及び残留物のFCC分解の間、分解触媒のニッケル脱水及びバナジウムアタックを低減させる。
不活性担体支持材料は、金属不動態化剤/捕捉剤を保持するために使用される。担体支持材料は、特に限定はされないが、(i)インサイチュFCC含有ゼオライト、(ii)焼成カオリン、(iii)アルミナ又は(iv)シリカから選択される。シリカを使用した場合、熱安定性付与のためジルコニウムを添加することができる。Sasol社製のPuralox(登録商標)のようなアルミナも有効である。微粒子の態様の焼成カオリンが好ましい。現状の発明で使用されうる担体の製造方法は、ここで参照された米国特許第7678735号に共通して選定される。使用される担体の量は、触媒混合物の約1質量%以上99質量%以下、好ましくは5質量%以上95質量%以下である。担体は、好ましくは、約5m2/g以上200m2/g以下の表面積を有する。
RSbM金属不動態化剤/捕捉剤は、通常、1)担体をアンチモン溶液に含浸させ、2)担体微粒子の細孔容積の一部だけが充填されるように、前記1)の処理済担体を酸化還元元素溶液に含浸させ、そして、3)細孔容積の残りの部分を濃水酸化アンモニウム溶液で充填させることで作製される。塩化アンチモン又は三酸化アンチモンがアンチモン溶液の作製に使用することができる
上述した方法に従い、反応温度は少なくとも約900°F(482℃)とする。上限は約1100°F(593.3℃)以上である。好ましい温度範囲は、約950°F以上1050°F以下(510℃以上565.6℃以下)である。反応全圧は、幅広く変化させることが可能であり、例えば、約5psig以上50psig以下(0.34気圧以上3.4気圧以下、34.45kPa以上344.51kPa以下)又は、好ましくは約20psig以上約30psig以下(1.36気圧以上 2.04気圧以下、137.80kPa以上206.70kPa以下)である。最大ライザー滞在時間は約5秒であり、ほとんどの原料油用には、滞在時間は約1秒から約2.5秒、又はそれ以下である。芳香族量が多い高分子量原料油用には、約0.5秒から約1.5秒の滞在時間が適しており、これにより、容易に分解され、高いガソリン収量をもたらす芳香族であるモノ‐及びジ‐芳香族及びナフタレンは分解されるものの、高収量のコークスとC2と軽質ガス(lighter gase)を生成するポリ芳香族の分解が明らかに起こる前に作業を終了させることができる。反応器の長さ対直径の比は広く変えることができるが、反応器は高線速度(例えば25フィート/秒以上75フィート/秒、即ち、7.6201m/秒以上22.8603m/秒以下)を付与するために十分延伸される必要があり、このため、長さ対直径の比は、約20以上約25以下が好ましい。反応器は均一な直径を持つことができるし、流路に沿って略一定の速度を維持するために、反応経路に沿って連続したテーパー又は段階的に直径を増加させてもよい。
Fe/Sb混合物を含む不動態化剤/捕捉剤を作製した。
1)アンチモン溶液
50mlビーカー内でSb2O3を適切量計量し、そのビーカーに30mlまで水を入れ、70℃迄加熱した。H2O2を加え、混合物を70℃で1時間保持した。下記反応が起こった。
焼成カオリン支持体をボールに入れ、工程1の溶液の約1/3で湿らせた。支持体を纏め、残り2/3の工程1の溶液で上記工程を繰り返した。湿った支持体をパイレックス(登録商標)製のボールに入れ、支持体を100℃通気オーブンで一晩乾燥させた。
50mlビーカーでFe(NO3)3・9H2Oを計量し、22mlまでビーカーを水で充填し、それらの成分をFe(NO3)3・9H2Oが溶解するまで混合した。
実施例1の工程に従い、多様なFb:Sb比の不動態化剤/捕捉剤を作製した。
プロモーターを含む金属不動態化剤/捕捉剤を作製した。
先ず、3.91gのSbCl3を、25mlの脱イオンH2Oと15mlのHCl(37%)に溶解させ、次いで、12.62gのFe(N03)3・9H20と3.53gのMn(N03)3・4H2Oを混合した。この混合物40mlを100gの焼成カオリンに加え、十分混合し、焼成カオリンを100℃で一晩(16時間)乾燥させた。取り込み後の担体を更に400℃3時間大気中で焼成した。収量%は、Fe2O3,が3.0862%、MnO2が1.0944%、Sb2O3が2.2779%であった。
