Abstract
Catalyseur à base d'argent et de métaux alcalins déposés sur un support obtenu en appliquant dans un ordre quelconque un composé d'argent décomposable par la chaleur et des composés de métaux alcalins sur support, puis en activant le catalyseur. Le catalyseur final contient, rapportés à la quantité d'argent, en plus d'une quantité efficace de lithium, 0,05 à 0,35 atomes % de potassium et/ou 0,03 à 0,25 atome % de rubidium et/ou 0,01 à 0,2 atome % de césium. Application de ce catalyseur à la préparation de l'oxyde d'éthylène par oxydation de l'éthylène avec de l'oxygène moléculaire.Catalyst based on silver and alkali metals deposited on a support obtained by applying in any order a silver compound decomposable by heat and alkali metal compounds on a support, then activating the catalyst. The final catalyst contains, based on the amount of silver, in addition to an effective amount of lithium, 0.05 to 0.35 atom% potassium and / or 0.03 to 0.25 atom% rubidium and / or 0.01 to 0.2 atom% cesium. Application of this catalyst to the preparation of ethylene oxide by oxidation of ethylene with molecular oxygen.
