Description
一実施形態においては、硫黄を、最小のオレフィン飽和で、オレフィン質ナフサから選択的に除去するための触媒は、(a)コバルト塩、(b)モリブデン塩、および(c)少なくとも一種の有機添加剤(有機配位子など)で含浸されているシリカ担持触媒である。シリカ担体は、シリカ担体基準でシリカ少なくとも約85重量%、好ましくはシリカ少なくとも約90重量%、特にはシリカ少なくとも約95重量%を含む。シリカ担体の例には、シリカ、MCM−41、シリカ結合MCM−41、フュームドシリカ、金属酸化物変性ケイ質担体、および珪藻土が含まれる。
シリカ担体は、従来の技術を用いて、CoおよびMo塩の水溶液で含浸された。有機配位子は、シリカ担体と接触させる前に、塩の水溶液へ添加されてもよい。シリカ担体を金属塩で含浸する一実施形態は、初期湿潤方法によるものである。初期湿潤は、従来の方法である。即ち、水素処理触媒の調製、製造、および使用における当業者に知られるものである。この方法においては、金属塩および有機添加剤を含む水溶液は、担体と、従来の技術を用いて初期湿潤点まで混合される。
触媒を、初期湿潤技術によって調製した。Davisilシリカ、フュームドシリカCab−O−Sil、MCM−41、Y/SiO2、Mg/SiO2、Ti/SiO2、およびZr/SiO2を、担体として調製した。調製の際に用いられるCoおよびMo前駆体化合物は、炭酸コバルト水和物およびヘプタモリブデン酸アンモニウム四水和物であった。有機添加剤のニトリロ三酢酸(NTA)を、含浸溶液で用いた。NTA/炭酸コバルト水和物のモル比は、0.5であった。
RT−225(Albemarle Corporation製造の商業Co/MoHDS触媒)、および分散助剤としてNTAを用いる本発明の担持CoMo触媒を、直留ナフサおよび3%H2Sを用いて硫化した。個々の触媒は、使用前には、焼成されなかった。
Y/SiO2、Mg/SiO2、Ti/SiO2、およびZr/SiO2のDavisilシリカおよび変性シリカ担体の選択性は、有機配位子としてのNTAを用いて、この実施例で、実施例1の調製方法および実施例2のHDS手順を用いて示される。図2は、ナフサの重量基準で、「%C5オレフィン飽和(重量基準):2−メチル−チオフェンの%HDS(重量基準)」のプロットを示すグラフである。図2で分かるように、触媒は、オレフィン飽和40〜60%未満をHDS60〜90%で有して、RT−225商業触媒に勝る実質的な選択性の向上を示した。
この実施例は、実施例1に従って調製されたDavisilシリカ担持CoMo触媒に対する有機配位子(添加剤)の効果を、実施例2の手順を用いて、HDS性能に関して示す。有機配位子は、グリセロール、酢酸、TEA、フェナントロリン、キノリノール、アセチルアセトネート、サリチル酸、およびNTAである。図3は、重量基準で「%C5オレフィン飽和:%2−メチル−チオフェンHDS」を示すグラフである。図3に示されるように、60〜95%HDS転化率では、全ての触媒は、RT−225商業触媒に勝る約30〜約60の選択性の向上を示した。触媒の調製に用いられた有機配位子の内で、NTAを用いて作製された触媒は、有機配位子(フェナントロリン、キノリノール、サルチル酸、酢酸、トリエタノールアミン(TEA)、グリセロール、およびアセチルアセトネートなど)を用いて作製された他の触媒より、良好な選択性を示した。しかし、有機配位子を用いて作製された触媒は、ベースケースRT―225に比較して、より良好な選択性を示した。
この実施例は、実施例1に従って調製されたDavisilシリカ担持CoMo触媒に対する有機配位子の別の組の効果を、実施例2の手順を用いて、HDS性能に関して示す。有機配位子は、NTA、グアニジン、エチレンジアミン四酢酸(EDTA)、シクロヘキサンジアミン四酢酸(CYDTA)、アラニン、およびアルギニンであり、これは、実施例4におけるように、RT−225に比較される。図4は、重量基準で「%C5オレフィン飽和:%2−メチル−チオフェンHDS」を示すグラフである。図4に示されるように、TNAおよびグアニジンを用いて作製された触媒は、他の有機配位子を用いて作製された触媒より良好な選択性を示す。しかし、有機配位子を用いて作製された触媒は、RT−225に比較して、より良好な選択性を示した。
