本発明においては、触媒を構成する各元素の出発原料は、モリブデン成分原料としてはモリブデン酸アンモニウムを使用した場合に高性能触媒が得られる。特にモリブデン酸アンモニウムには、ジモリブデン酸アンモニウム、テトラモリブデン酸アンモニウム、ヘプタモリブデン酸アンモニウム等、複数種類の化合物が存在するが、その中でもヘプタモリブデン酸アンモニウムを使用した場合が最も好ましい。ビスマス成分原料としては硝酸ビスマスを使用した場合に高性能な触媒が得られる。鉄、コバルト、ニッケル及びその他の元素の原料としては通常は酸化物あるいは強熱することにより酸化物になり得る硝酸塩、炭酸塩、有機酸塩、水酸化物等又はそれらの混合物を用いることができる。例えば、鉄成分原料とコバルト成分原料及び/又はニッケル成分原料を所望の比率で10~80℃の条件下にて水に溶解混合し、20~90℃の条件下にて別途調合されたモリブデン成分原料およびZ成分原料水溶液もしくはスラリーと混合し、20~90℃の条件下にて1時間程度加熱撹拌した後、ビスマス成分原料を溶解した水溶液と、必要に応じX成分原料、Y成分原料とを添加して触媒成分を含有する水溶液またはスラリーを得る。以降、両者をまとめて調合液(A)と称する。
次いで上記で得られた調合液(A)を乾燥し、乾燥粉体とする。乾燥方法は、調合液(A)を完全に乾燥できる方法であれば特に制限はないが、例えばドラム乾燥、凍結乾燥、噴霧乾燥、蒸発乾固等が挙げられる。これらのうち本発明においては、スラリーから短時間に粉体又は顆粒に乾燥することができる噴霧乾燥が特に好ましい。噴霧乾燥の乾燥温度はスラリーの濃度、送液速度等によって異なるが概ね乾燥機の出口における温度が70~150℃である。また、この際得られる乾燥粉体の平均粒径が10~700μmとなるよう乾燥することが好ましい。こうして乾燥粉体(B)を得る。
得られた乾燥粉体(B)は空気流通下で200℃から600℃で、好ましくは300℃から600℃で焼成することで触媒の成型性、機械的強度、触媒性能が向上する傾向がある。焼成時間は1時間から12時間が好ましい。こうして予備焼成粉体(C)を得る。
成型方法に特に制限はないが円柱状、リング状に成型する際には打錠成型機、押し出し成型機などを用いた方法が好ましい。さらに好ましくは、球状に成型する場合であり、成型機で予備焼成粉体(C)を球形に成型しても良いが、予備焼成粉体(C)(必要により成型助剤、強度向上剤を含む)を不活性なセラミック等の担体に担持させる方法が好ましい。ここで担持方法としては転動造粒法、遠心流動コーティング装置を用いる方法、ウォッシュコート方法等が広く知られており、予備焼成粉体(C)が担体に均一に担持できる方法で有れば特に限定されないが、触媒の製造効率や調製される触媒の性能を考慮した場合、より好ましくは固定円筒容器の底部に、平らな、あるいは凹凸のある円盤を有する装置で、円盤を高速で回転させることにより、容器内にチャージされた担体を、担体自体の自転運動と公転運動により激しく撹拌させ、ここに予備焼成粉体(C)並びに必要により、成型助剤および/または強度向上剤、細孔形成剤を添加することにより粉体成分を担体に担持させる方法が好ましい。尚、担持に際して、バインダーを使用するのが好ましい。用いうるバインダーの具体例としては、水やエタノール、メタノール、プロパノール、多価アルコール、高分子系バインダーのポリビニルアルコール、無機系バインダーのシリカゾル水溶液等が挙げられるが、エタノール、メタノール、プロパノール、多価アルコールが好ましく、エチレングリコール等のジオールやグリセリン等のトリオール等がより好ましい。グリセリン水溶液を適量使用することにより成型性が良好となり、機械的強度の高い、高性能触媒が得られ、具体的にはグリセリンの濃度5重量%以上の水溶液を使用した場合に特に高性能触媒が得られる。これらバインダーの使用量は、予備焼成粉体(C)100重量部に対して通常2~80重量部である。不活性担体は、通常2~8mm程度のものを使用し、これに予備焼成粉体(C)を担持させるが、その担持率は触媒使用条件、たとえば反応原料の空間速度、原料濃度などの反応条件を考慮して決定されるものであるが、通常20重量%から80重量%である。ここで担持率は以下の式(3)で表記される。こうして成型体(D)を得る。成形体(D)は工程e)の本焼成前に乾燥させ、使用したバインダーの一部を蒸発させることもできる。
担持率(重量%)
=100×〔成型に使用した予備焼成粉体(C)の重量/(成型に使用した予備焼成粉体(C)の重量+成型に使用した不活性担体の重量+成型に使用した成型助剤と強度向上剤の重量)〕
成型体(D)は200~600℃の温度で1~12時間程度焼成することで触媒活性、有効収率が向上する傾向にある。焼成温度は400℃以上600℃以下が好ましく、500℃以上600℃以下がより好ましい。流通させるガスとしては空気が簡便で好ましいが、その他に不活性ガスとして窒素、二酸化炭素、還元雰囲気にするための窒素酸化物含有ガス、アンモニア含有ガス、水素ガスおよびそれらの混合物を使用することも可能である。こうして触媒(E)を得る。焼成温度を高くすることで適宜活性を抑制することができる。そのような触媒は、例えばホットスポットが発生するような原料ガス入口側で使用することができる。
