Description
水の存在下で重質炭化水素油を触媒に接触させて軽質炭化水素油を製造する重質炭化水素油の分解方法であって、
前記触媒がセリウム元素を含有し、
さらに、鉄元素及び第4A族元素を含有し、
前記鉄元素の含有量が5〜30質量%であり、
前記セリウム元素、鉄元素及び第4A族元素は、各々酸化物であり、セリウム元素、鉄元素、及び第4A族元素のモル数が下記式(I):
{(セリウム元素のモル数)}+(第4A族元素のモル数)}/鉄元素のモル数>1.0・・・(I)
の関係を満たすことを特徴とする。
前記触媒は、セリウム元素を2.0質量%以上の量で含有するのが望ましい。
また、前記触媒が、第4A族元素を15〜60質量%の量で含有していてもよい。
本発明の重質炭化水素油の分解方法は、
水の存在下で重質炭化水素油を触媒に接触させて軽質炭化水素油を製造する重質炭化水素油の分解方法であって、
前記触媒がセリウム元素を含有し、
さらに、鉄元素及び第4A族元素を含有し、
前記鉄元素の含有量が5〜30質量%であり、
前記セリウム元素、鉄元素及び第4A族元素は、各々酸化物であり、セリウム元素、鉄元素、及び第4A族元素のモル数が下記式(I):
{(セリウム元素のモル数)}+(第4A族元素のモル数)}/鉄元素のモル数>1.0・・・(I)
の関係を満たすことを特徴としている。
{(セリウム元素のモル数)}+(第4A族元素のモル数)}/鉄元素のモル数>1.0・・・(I)
上記式(I)を満たすこと、すなわち、セリウム元素のモル数と第4A族元素のモル数との合計が鉄元素のモル数を超えることにより、上述のように酸化鉄が還元されて凝集することで触媒活性が劣化するのを抑制するとともに、格子酸素の供給速度が向上することでさらに有効に触媒活性の劣化を抑制するものと推定される。
触媒Aとして、表1に示す組成のZ-1407(第一稀元素化学工業製)を用いた。触媒Aの結晶構造をXRDにより解析したところ、酸化ジルコニウムのピークがわずかに検出されたのみで酸化セリウム、酸化鉄のピークは全く検出されなかった。
Fe(NO3)3・9H3O:226.2g、Al(NO3)3・9H2O:52.5g、ZrOCl2・8H2O:11.3gを水道水1.5リットルに攪拌溶解した。次いで、NaOH溶液(48.7%)を徐々に加えながら、1時間攪拌した。その後、固液分離を行い、得られた固形分を熱湯でろ過洗浄した。次いで、得られたケーキ状のろ過物を、500℃で1時間熱処理して、56gの触媒Bを得た。得られた触媒Bの組成を表1に示す。触媒Bの結晶構造をXRDにより解析したところ、ヘマタイト構造の酸化鉄のピークが明確に検出された。
ステンレス製の反応器(内容積10ml)中に、触媒Aを6.0mL充填した。次いで、触媒Aを充填した反応器内にイオン交換水を1.5mL/hで流通させつつ、同時に窒素を5mL/minで流通させながら、常圧下で500℃まで加熱した後、水素を添加することなく、ベンゼンで10倍に希釈した重質炭化水素油(減圧残油/常圧残油=50/50(質量比)の混合重質炭化水素油、重量平均分子量=2,200)を1.1ml/hの速度で反応器内に投入した。得られた生成油の重量平均分子量は332であり、その分子量分布図を図1に示す。なお、重量平均分子量は、ゲル浸透クロマトグラフィーを用いてポリスチレン換算値により求めた。
触媒Bを用いた以外、実施例1と同様にして重質炭化水素油を投入した。得られた生成油の重量平均分子量は495であり、その分子量分布図を図2に示す。
なお、実施例1及び比較例1に供した原料の重質炭化水素油の分子量分布を図3に示す。
