Abstract
Description
(1)第一反応塔(原料油が最初に導入される反応塔)の入口、あるいは
(2)各触媒床の間や複数の反応塔を持つ場合には反応塔と反応塔との間から、
の二通りの注入法がある。本発明において(1)のみあるいは(1)と(2)の両方といったいずれの方法も採用することができるが、好ましくは(1)と(2)の両方から水素ガスを注入する方法が好ましい。そして、より確実に副生する硫化水素を除去し、効率よく脱硫・芳香族水素化を進行せしめるためには、水素ガス全注入量のうち好ましくは60容量%以下は(1)から注入し、残りの水素ガスは(2)から注入することが好ましい。さらに、(1)から注入される水素ガス量が水素ガス全注入量のうち55容量%以下であることがより好ましく、40容量%以下であることがさらに好ましく、30容量%以下であることが特に好ましい。すなわち、(2)から注入される残りの水素ガスの量が多いほど水素ガスの添加効果がより効率良く発揮される傾向にある。なお、ここでいう第一反応塔の入口とは、原料油を所定の温度まで温める加熱炉の手前でもよく加熱炉出口でもよい。
反応温度390℃、水素圧力18MPa、LHSV1.2h−1、水素/油比200NL/Lという反応条件とした以外は実施例1と同様にして水素化処理試験を実施した。
