Abstract
การประดิษฐ์นี้จะเกี่ยวข้องกับสารพาหะของคะตะลิสต์ ที่จะถูกใช้เป็นสารรองรับ สำหรับส่วนประกอบของตะคะลิสต์ที่เป็นโลหะ และออกไซด์ของโลหะ ของการใช้ใน ชนิดต่างๆ ของปฎิกิริยาทางเคมี โดยเฉพาะอย่างยิ่ง , การประดิษฐ์จะจัดให้มีกระบวนการ ของการสร้างสารพาหะชนิดแอลฟา อะลูมินา ซึ่งจะเหมาะสมเป็นสารรองรับสำหรับซิลเวอร์ , และการใช้ของคะตะลิสต์ดังกล่าวนี้ในปฎิกิริยาทางเคมี , โดยเฉพาะ อีพอกซิเดชันของ เอทธิลีนไปเป็นแอทธิลีน ออกไซด์ สารผสมจะประกอบด้วยไฮเดรเทด พรีเคอเซอร์ของ แอลฟา อะลูมินา อย่างน้อยหนึ่งชนิด ; แอลฟา อะลูมินาที่เลือกได้ ; และสารประสาน สารผสมจะปราศจากอนุภาคล่อผลึกอย่างแท้จริง The invention will involve catalyst carriers. To be used as a support For metal takalist components And metal oxides of use in various kinds of chemical reactions. In particular, the invention will provide a process. Of the production of alpha alumina carriers which would be suitable as a supporting agent for silver, and the use of such catalists in chemical reactions, especially epoxidation of Ethylene to ethylene oxide, mixtures contain hydrated At least one type of alpha alumina precancer; Selectable alpha alumina; And the compound mixture will be absolutely free of crystalline particles
