Description
ΔH298K=46.1kJ/mol
式(I)の反応は、吸熱反応であるため、安定したアンモニア分解率を得るためには反応系に熱を与えて反応温度350℃以上にする必要がある。
ΔH298K=−315.1kJ/mol
式(I)と式(II)の反応を同一の反応管内で起こさせると式(I)の吸熱分を式(II)で発生する熱で補うことが可能となる。また、式(II)の酸素量を制御することで触媒層温度を制御することができる。例えば、エンジン排ガスの廃熱を熱交換して予熱された供給ガス温度が変動する場合において、安定して水素を製造することが可能となる。
CeO2+2x/3NH3→CeO2−x+xH2O+x/3N2(0<x<2)
上記還元後の触媒がアンモニア酸化・分解反応に供される。アンモニア酸化・分解触媒の還元処理は、同触媒反応器に充填する前に行っても後に行ってもよい。
触媒担体として、ZrO2のモル濃度が10、20、50、80%である4種の市販のCeO2−ZrO2(第一稀元素化学工業(株)製)を用いた。
上記の触媒担体に触媒活性金属を担持させた。触媒活性金属は、貴金属であるRu、Pt、Rh、Pt−Rhおよび卑金属であるCo、Ni、Fe、Cu、Mo、Mnを用いた。触媒担持量はすべて2重量%となるようにした。
上記各金属の触媒担体上への担持は、各金属の前駆体である各金属塩を純水に溶解させ、この溶液に、上記の触媒担体を、触媒活性金属の担持量が2重量%(金属として)になるように分散させた。
600cpiのコーディエライト上にウォッシュコート法を用いて約250g/Lの触媒担持量になるまで触媒活性金属を担持させた。
(触媒の還元処理)
得られた各ペレット状触媒1gまたはハニカム状触媒4mLを流通型反応管に充填した後、水素気流中還元処理温度を150℃から800℃までにわたって50℃刻みとして処理した。還元処理時間は2時間とした。
上記の反応管に充填された各温度で還元処理された触媒を、窒素雰囲気下、25℃で保持し、その後、酸素(空気)とアンモニアを同時に触媒層に供給した。アンモニア供給量は2.5NL/分と一定にし、空気供給量は空気/アンモニアの体積比1.0とした。触媒層温度と出口ガス組成を、それぞれ、熱電対と質量分析計により計測した。
(触媒の還元処理)
得られた各ペレット状触媒1gまたはハニカム状触媒4mLを流通型反応管に充填した後、水素気流中600℃で2時間にわたって還元処理を行った。
上記の反応管に充填された還元処理された触媒を、窒素雰囲気下に冷却し、所定の温度に達した後に、酸素(空気)とアンモニアを同時に供給した。アンモニア供給量は1NL/分と一定にし、空気供給量は空気/アンモニアの体積比1.0とした。触媒層の温度と触媒層出口における水素発生量を、それぞれ、熱電対と質量分析計により計測した。
