Abstract
Description
最近、ナフテン系基油は、変圧器油、絶縁油、冷凍機油、ゴムおよびプラスチックのプロセス油、印刷インキまたはグリースの基礎材料、および金属加工油の基油など、多様な産業分野で幅広く用いられている。
本発明によれば、厳しい条件下で水素化処理を施すことにより、不純物の水準を顕著に減らすことができ、これにより、後続の脱ろう段階で異性化反応が活発に起こるので、高品質の製品を高収率で生産することが可能になる。
本発明に係る工程は、図1に示すように、石油系炭化水素の流動接触分解工程(FCC)を介して得られる軽質サイクル油(LCO)およびスラリー油(SLO)を水素化処理工程(R1)に供給して水素化処理する段階、前記水素化処理された留分を脱ろう工程(R2)に供給して脱ろうする段階、および脱ろうされた留分を分離装置(V2)を用いて粘度範囲によって分離する段階を含む。
本発明に係る方法の供給原料として、LCOおよびSLOは、それぞれ単独で使用してもよく、所定の割合で混合して使用してもよい。
軽質サイクル油からのナフテン系基油の製造
流動接触分解工程(FCC)を介して沸点310〜380℃の軽質サイクル油留分(LCO)を分離して水素化処理反応器に供給した。
水素化処理は、水素化処理用触媒としてコバルト−モリブデンおよびニッケル−モリブデンの組み合わせ触媒を使用し、LHSV0.5〜2.0hr-1、供給原料に対する水素の体積比1000〜2000Nm3/m3、反応圧力120〜160kg/cm2gおよび温度300〜400℃の条件で行われた。
軽質スラリー油からのナフテン系基油の製造
FCCを介して得られた沸点345℃以上のスラリー油を、真空蒸留装置(VDU)を用いて、軽質留分、中間留分、残油留分に分離した。残油留分を除いた軽質留分または中間留分を水素化処理反応器に供給した。本実施例では、沸点360〜480℃の軽質留分を供給原料として用い、ナフテン系基油を製造した。
水素化処理段階後、得られた中間留分は110ppm未満の硫黄含量であり、10wt%以下の量で多環芳香族炭化水素を含有していた。
軽質サイクル油と軽質スラリー油との混合留分からのナフテン系基油の製造
実施例1でFCCを介して分離されたLCOと、実施例2でVDUを用いて分離されたLt−SLOを同一の体積比で混合して供給原料として使用した。
水素化処理段階は、Nippon Ketjen社のニッケル−モリブデン組み合わせ触媒を使用し、LHSV0.5〜2.0hr-1、供給原料に対する水素の体積比1300〜2000Nm3/m3、反応圧力130〜190kg/cm2、および温度340〜400℃の条件で行った。
その後、脱ろうを、市販の(Pt/Pd)/ゼオライト/アルミナ成分の異性化脱ろう触媒および水素化仕上げ触媒を使用して、LHSV0.5〜2.0hr-1、供給原料に対する水素の体積比400〜1000Nm3/m3、反応圧力130〜160kg/cm2gの条件で行った。このため、反応温度は、異性化脱ろう段階では300〜370℃、水素化仕上げ段階では210〜300℃に設定した。
スラリー油からのナフテン系基油の製造
FCCを介して得られた沸点345℃以上のSLOを供給原料として用いてナフテン系基油を製造した。
水素化処理段階は、Nippon Ketjen社のニッケル−モリブデン組み合わせ触媒を使用し、LHSV0.5〜2.0hr-1、供給原料に対する水素の体積比1500〜2000Nm3/m3、反応圧力150〜200kg/cm2g、および温度350〜400℃の条件下で行った。
その後、脱ろうを、市販の(Pt/Pd)/ゼオライト/アルミナからなる異性化脱ろう触媒および水素化仕上げ触媒を使用して、LHSV0.5〜2.0hr-1、供給原料に対する水素の体積比400〜1000Nm3/m3、反応圧力140〜160kg/cm2gの条件で行った。このため、反応温度は、異性化脱ろう段階では320〜370℃、水素化仕上げ段階では210〜300℃に設定した。
