Description
沈殿生成装置(中和沈殿槽)では、原料溶解装置で調製した触媒成分物質の溶液とアルカリ等の添加物質の溶液を混合して沈殿を生成させる。
濾過装置では、湿式粉砕装置で微粉砕処理したスラリーを濾過し、必要に応じて濾過ケーキの洗浄を行う。
スラリー化槽では、濾過装置から排出された濾過ケーキに水を加えてスラリーにし、湿式粉砕装置へ供給する原料スラリーを調製する。
湿式粉砕装置では、スラリー化槽から排出された沈殿物(スラリー)を湿式粉砕機へ装入し、50%粒径が1μm以下、好ましくは0.8μm以下程度になるように微粉砕する。
水分調整槽では、湿式粉砕されたスラリーに、水を加え、噴霧乾燥に適した水分量のスラリーを調整する。
乾燥造粒工程は水分調整槽から排出された原料スラリーを乾燥すると共に粒状物にする工程であって、噴霧乾燥装置を有している。
(比較例1)
原料スラリーを湿式粉砕処理せずに、噴霧乾燥機へ供給して乾燥造粒し、焼成した。この試験においては、原料スラリーを湿式粉砕処理せずに、噴霧乾燥機へ供給したこと以外は、実施例1と同じ条件により、触媒を製造した。このとき、噴霧乾燥機へ供給したスラリー中の粒子の大きさは50%粒径が10μmであった。又、噴霧乾燥により得られた粒状物の粒度は50%粒径が80μmであった。
Claims (2)
- 一酸化炭素の水素化反応の触媒成分物質を含有する原料スラリーを乾燥造粒し、得られた粒状物を焼成する触媒の製造方法において、乾燥造粒する前に前記原料スラリーをその中の触媒成分物質の50%粒径が0.8μm以下になるように湿式粉砕処理することを特徴とするスラリー床反応用触媒の製造方法
- 乾燥造粒する方法が噴霧乾燥法であることを特徴とする請求項1に記載のスラリー床反応用触媒の製造方法
