| titleOfInvention | Preparation method of octylene aldehyde gas phase hydrogenation catalyst for octanol production |
| abstract | The invention discloses a preparation method of octylene aldehyde gas phase hydrogenation catalyst for octanol production. The method comprises: firstly, adopting coprecipitation to add mixed aqueous solution of copper nitrate and zinc nitrate and aqueous solution of precipitator into a reactor for neutralization, obtaining copper and zinc precipitate; secondly, adopting cocurrent coprecipitation add mixed aqueous solution of zinc nitrate and aluminium nitrate and aqueous solution of precipitator into a reactor for neutralization, obtaining copper, zinc and aluminum precipitate; thirdly, ageing the precipitate, washing, filtering, drying, pelletizing and roasting to obtain powder material; fourthly, adding graphite and deionized water to the powder material and tabletting to obtain the catalyst. The invention adopts fractional continuous coprecipitation method to effectively increase specific surface area of the catalyst, to increase hydrogenation activity of the catalyst and to improve thermal stability of the catalyst. Furthermore, the coprecipitation is finished in the same rector to simplify the technical process, to save the equipment investment, to reduce the production cost and to realize industrialized production more easily. |
