| titleOfInvention | Silver catalyst carrier, its preparation method, the catalyst be made up of it and application |
| abstract | The invention provides a kind of carrier of silver catalyst, this carrier comprises following component: the Al of a, 85 ~ 99.9wt%n 2 on 3 , wherein Alpha-alumina is>=85wt% based on aluminium oxide gross weight; B, compound Zirconium oxide containing zirconium and metal M, wherein metal M is be selected from one or more elements in periodic table of elements IIA race, IIIB race and the IVB race element except zirconium, and in this compound Zirconium oxide, the total amount of metallic element accounts for total weight of carrier content is 0.01-10wt%; With alkaline-earth metal and/or its compound of c, one or more periodic table of elements IIA race; It is 0.01-5wt% that its metallic element weight accounts for total weight of carrier content.The silver catalyst be made up of this carrier is produced in the process of oxirane at ethylene and is demonstrated good activity and selectivity, and especially selective tool has clear improvement.In addition, the invention still further relates to the preparation method of described carrier, and the silver catalyst be made up of this carrier and application thereof. |
