SILVER CATALYST FOR PRODUCTION OF ETHYLENE OXIDE, METHOD OF PREPARING CATALYST AND ETHYLENE OXIDE PRODUCTION PROCESS Russian patent published in 2001 - IPC

FIELD: organic synthesis catalysts. SUBSTANCE: catalyst contains support including alumina as chief component and also silicon oxide and metal or a compound of at least one Ib or IIb-group element, such as, for instance, silver oxide, as well as precipitated silver as active component. Support is prepared by mixing at least alpha-alumina, silicon compound, organic binder, and compound of at least one Ib or IIb-group element, after which mixture is calcined at 1000 to 1800 C. Silver is applied onto support in proportion of 1 to 30 wt %. Catalyst may also contain alkali metal in amounts between 0.01 and 100 mcmol per 1 sq.m of catalyst surface. EFFECT: increased selectivity and lifetime of catalyst. 14 cl, 1 tbl, 15 ex
