Description
本出願は、2020年06月19日付の韓国特許出願第10-2020-0074931号に基づく優先権の利益を主張し、当該韓国特許出願の文献に開示された全ての内容は本明細書の一部として組み込まれる。
本記載のステップS1は、一例として、アルミナ前駆体を1次焼成して、αアルミナ1~15重量%、θアルミナ60~95重量%及びδアルミナ4~25重量%を含む混合相アルミナを形成するステップであり、この場合に、高い破砕強度及び耐化学性を有する触媒の製造が可能であるという利点がある。
本記載のステップS2は、一例として、前記混合相アルミナを水蒸気で前記1次焼成温度よりも低い温度でスチーム処理して活性化させるステップである。
本記載のステップS3は、一例として、ステップS2で活性化された混合相アルミナを2次焼成温度で焼成するステップである。
ベーマイト(Boehmite)を1100℃の条件で10時間、空気雰囲気下で焼成して、αアルミナ10重量%、θアルミナ70重量%及びδアルミナ20重量%を含んでなる混合相アルミナを得、前記混合相アルミナを管型反応器内に充填した後、温度を400℃に調節し、その後、反応器内に水蒸気と窒素を3時間供給してスチーム処理した。このとき、水蒸気は、HPLCポンプを用いて0.026~0.1g/minで供給し、窒素は、マスフローコントローラ(Mass Flow Controller;MFC)を用いて133ml/minで供給し、窒素と水蒸気の混合比は、N2:H2Oの体積比でN2:H2O=2500:1であり、水蒸気:混合相アルミナの重量比は0.01~100:1とした。また、スチーム処理の後に、550℃で5時間焼成してアルミナ触媒を収得した。
前記実施例1のスチーム処理において、水蒸気と窒素の供給を3時間の代わりに6時間にした以外は、前記実施例1と同様の方法で行った。
ベーマイトを1100℃の条件で10時間、空気雰囲気下で焼成して混合相アルミナを収得した。このとき、収得された混合相アルミナは、αアルミナ10重量%、θアルミナ70重量%、δアルミナ20重量%及びγアルミナ0重量%であった。
前記実施例1において、550℃で5時間焼成するステップを排除した以外は、前記実施例1と同様の方法で行った。
前記実施例1~2及び比較例1~2で製造された触媒の特性を、下記の方法で測定し、その結果を下記の表1と図1及び図2に示した。
前記製造された触媒は、イソプロピルアルコール(IPA)の脱水反応によりプロピレンを生成する反応を介して触媒活性を評価した。
前記製造された触媒の表面の物理的な性状の変化を確認するためにSEMイメージを活用した。
前記製造されたアルミナ触媒の結晶構造をX線回折(XRD;X-ray Diffraction)を通じて確認し、図2に示した。
