Description
分解率(%)=[(被処理ワックス単位質量中の沸点が360℃を超える炭化水素の質量)−(水素化分解生成物単位質量中の沸点が360℃を超える炭化水素の質量)]×100/(被処理ワックス単位質量中の沸点が360℃を超える炭化水素の質量)…(1)
<新規水素化精製触媒の調製>
粉末状のシリカジルコニア(シリカ単位/ジルコニア単位モル比が7)を60質量%と粉末状のアルミナを40質量%とを含有する組成物に水を加えて粘土状に混練して捏和物を調製した。この捏和物を押出成型により直径約1.5mm、長さ約3mmの円柱状に成型した。得られた成型体を120℃で3時間乾燥し、更に空気中、450℃で3時間焼成して担体を得た。
上記により得られた水素化精製触媒を固定床流通式反応器に充填し、水素気流下、340℃で4時間の還元処理を行って触媒を活性化した。
<再生水素化精製触媒の調製>
(炭素分測定工程)
参考例により得た使用済み触媒から一部試料を採取し、ヘキサンにて十分に洗浄した後、減圧乾燥器にて70℃で2時間乾燥した。この試料中に含まれる炭素質物質を堀場製作所社製炭素・硫黄分析装置EMIA−920Vにより定量した。その結果、使用済み触媒はその乾燥全質量に対して、炭素原子として3.5質量%の炭素質物質を含有していた。また、試料のヘキサン洗浄・乾燥の前後における質量変化から、使用済み触媒の炭化水素含有量は触媒の乾燥全質量に対して9質量%と算出された。
使用済み水素化精製触媒に対して、窒素気流中400℃にて3時間、脱油処理を行なった。
脱油した使用済み触媒を加熱炉内に触媒前駆体を仕込み、空気雰囲気下、300℃まで昇温し、その後300〜400℃の間を10℃/hの昇温速度で昇温し、その後500℃にて2時間焼成することにより、再生水素化精製触媒を得た。得られた再生水素化精製触媒中の炭素質物質を前述の炭素・硫黄分析装置により定量した結果、触媒の全質量を基準とし、炭素原子換算で0.05質量%であった。

(第1脱油工程)
参考例により得た使用済み触媒に対して、窒素気流中400℃にて3時間、脱油処理を行なった。

参考例の「新規水素化精製触媒による炭化水素油の製造」において得られた軽油留分に上記予備再生触媒を浸漬した。
前記予備再生触媒を軽油留分中より引き上げ、窒素気流中400℃にて3時間、脱油処理を行なった。
第2脱油工程を経た予備再生触媒を、第1焼成工程における昇温条件と同一の条件で昇温後、450℃にて1時間焼成して再生水素化精製触媒を得た。この再生水素化精製触媒中の炭素質物質の含有量は炭素原子換算で0.2質量%であった。
