R−(COOH)n
(式中、nは、1〜3であり、Rは、ニトロ基、アミノ基、水酸基またはアルコキシル基のうち1種以上により置換されていてもよい、環状または脂肪族の、飽和または非飽和部位を表す。)を有するカルボン酸である。適切な酸の特定の例には、限定の意図なく、ギ酸、酢酸、クエン酸、コハク酸、マロン酸、プロピオン酸、酪酸、吉草酸、カプロン酸、グルタル酸、アジピン酸、乳酸、安息香酸、フタル酸、サリチル酸、アスコルビン酸、シュウ酸などが含まれる。炭酸は、弱有機酸の範囲内に含まれる。炭酸を含浸させるには、溶液が二酸化炭素で飽和しており、溶液中に二酸化炭素の存在を維持するのに併せて、雰囲気中の二酸化炭素の分圧が十分にあることが必要である。好適な弱有機酸には、限定されるものではないが、酢酸およびクエン酸が含まれる。これらの酸の2つ以上の組み合わせを用い得るが、一般には、それらを個別に用いることが好ましい。
ワックス中のチタニア担体担持コバルト系触媒の塊83g(200日間を超えて運転中のフィッシャー−トロプシュ反応器から回収)をビーカーに入れ、トルエンで覆った。混合物を85〜90℃に加熱し、手動で撹拌した。加熱/撹拌中に、塊をバラバラに砕いた。5分後、トルエン/ワックス溶液をデカントして新たなトルエンを加え、この処理を更に二回繰返した。三回目のデカントの後、残ったトルエン/触媒スラリーをブフナーロートに移し、高温でろ過した。高温のトルエンをろ過ケーク上に3回注ぎ、ろ過ケークを減圧吸引した。ろ過ケークを、ロート上で減圧を掛けて乾燥して、非発火性触媒58.4gを得た。触媒は、その高い透磁率によって示されるように、相当量の還元コバルトを含んでいた。触媒は、小さな永久磁石によって容易に動かされた。第二の試料を、ロート上で乾燥した後、終夜空気乾燥するという更なる工程を加えた、同様の方法で調製した。その特性は同じであった。
例1に従って調製された触媒(120g)を、固定床反応器に充填した。これを窒素により30分間パージングした。反応器の温度を100℃に上昇し、ガス流を10%水素/窒素に変更した。次いで、温度を288℃に上昇し、ガス流を純水素450sccmとした。触媒を3時間維持して、有機化合物の除去を完了し、金属化合物を還元した。反応器を冷却し、100℃未満に低下した際に、ガス流を窒素に変更した。反応器が雰囲気温度に冷却した際に、触媒を窒素雰囲気下で抜き出し、還元触媒118.4gを得た。触媒は相当量の金属コバルトを含み、また永久磁石により容易に動かされた。
例1からの触媒を、実験室固定床反応器で試験した。触媒(2ml、2.80g)を石英希釈材(4ml、6.54g)と混合し、内径1cmの管状反応器に入れた。ガラスウール栓を用いて、触媒床をしかるべき場所に保持した。多点熱電対を床に挿入して、温度を監視した。初期段階で375℃、19.7気圧、水素315sccmの条件で、触媒を2時間に亘って水素で還元した。アルゴン10sccmおよび水素260sccmの流れの下で、触媒を、19.7気圧で177℃に冷却した。冷却後、供給物組成をアルゴン12sccm、水素134sccmおよび一酸化炭素/二酸化炭素混合物94sccmに変更した。これは、H256.0%、CO211.6%、Ar4.9%およびCO27.5%(%はモル%として示される)の名目原料組成を示した。次いで反応器を、2.8℃/時間で199℃に加熱し、その温度で24時間保持した。その後、反応器を2.8℃/時間で213℃に加熱し、その温度で試験の残りの間保持した。
例1からの触媒30gをセラミック皿におき、300℃で2時間空気中で焼成した。焼成触媒を、乾燥した暗灰色の粉末として回収した。例3に示された手順に従って、焼成触媒の触媒活性試験を行った。CO転化率は55.0%であり、メタン選択性は10.9%であった。これらの条件下で24時間後に、CO転化率は52.4%であり、メタン選択性は10.5%であった。この例では、失活触媒を空気焼成することによって触媒活性が回復されうることが示される。
例2に従って調製された触媒(3.2g)を、窒素雰囲気下で2オンス(59.15cm 3 )の瓶に入れ、水0.82mlを初期湿潤まで加えた。次いで、含浸触媒を空気雰囲気下で1時間おき、その後減圧オーブン中80℃で乾燥し、引き続き300℃で2時間空気中で焼成した。例3に示された手順に従って、触媒の触媒活性試験を行った。CO転化率は55.1%であり、メタン選択性は9.5%であった。これらの条件下で24時間後に、CO転化率は52.8%であり、メタン選択性は9.2%であった。
氷酢酸7.21gを脱イオン水に加え、容量50mlに希釈することによって溶液を調製した。酢酸溶液2.75gを、不活性条件下で例2からの触媒10gに加えた。次いで、試料を空気雰囲気下において、激しく混合した。緩やかな発熱が生じ、これは数分後に静まった。空気中で更に2時間後、試料は緑味灰色であった。試料を100℃で1時間乾燥し、次いで300℃で2時間焼成した。暗灰色の粉末10.11gを回収した。例3に示された手順に従って、触媒の触媒活性試験を行った。CO転化率は82.1%であり、メタン選択性は7.1%であった。この条件下で1日後に、CO転化率は78.1%であり、メタン選択性は7.3%であった。
ギ酸5.52gを脱イオン水に加え、容量50mlに希釈することによって溶液を調製した。ギ酸溶液2.80gを、不活性条件下で例2からの触媒10gに加えた。次いで、試料を空気雰囲気下において、激しく混合した。その結果生じた緩やかな発熱は数分後に静まった。空気中で更に2時間後、試料は緑味灰色であった。試料を100℃で1時間乾燥し、次いで300℃で2時間焼成した。暗灰色の粉末10.4gを回収した。
クエン酸23.05gを脱イオン水に加え、容量50mlに希釈することによって溶液を調製した。クエン酸溶液2.77gを、不活性条件下で例2からの触媒10gに加えた。次いで、試料を空気雰囲気下において、激しく混合した。緩やかな発熱が生じ、これは数分後に静まった。空気中で更に2時間後、試料は明るい灰色であった。試料を100℃で1時間乾燥し、次いで300℃で2時間焼成した。暗灰色の粉末約10gを回収した。例3に示された手順に従って、触媒の触媒活性試験を行った。CO転化率は64.1%であり、メタン選択性は7.1%であった。この条件下で1日後に、CO転化率は60.9%であり、メタン選択性は7.1%であった。
例1からの触媒30gをセラミック皿におき、300℃で2時間空気中で焼成した。物質を、乾燥した暗灰色の粉末として回収した。
氷酢酸7.21gを脱イオン水に加え、容量50mlに希釈することによって溶液を調製した。溶液2.01gを、例9からの触媒9.07gに加えた。次いで、試料を空気雰囲気下において、激しく混合した。発熱は生じなかった。空気中で更に2時間後、試料は灰色であった。試料を100℃で1時間乾燥し、次いで300℃で2時間焼成して、暗灰色の粉末9.04gを回収した。例3に示された手順に従う触媒の試験において、CO転化率は48.1%であり、メタン選択性は7.35%であることが示された。
溶液pHの低下が止まるまで、ドライアイスを脱イオン水に溶解することにより、溶液を調製した。pHは約4〜6.8に達した。炭酸溶液2.70gを、不活性条件下で例2からの触媒10gに加えた。次いで、試料を空気雰囲気下において、激しく混合した。緩やかな発熱が生じ、これは数分後に静まった。空気中で更に4時間後、試料は灰色であった。試料を100℃で1時間乾燥し、次いで300℃で2時間焼成した。暗灰色の粉末9.4gを回収した。
