Abstract: The parent patent describes a catalyst for ethylene oxide prodn. consisting of Ag and alkali metal, or their cpds., on a carrier. The catalyst contains (atom % on Ag) Na 0.1-2% and either K 0.05-0.35%; Rb 0.03-0.25% or Cs 0.0005-0.2% (or mixts. of the heavier metals). The first addition describes similar catalysts contg. only 0.0005-0.0005% Cs or 0.003-0.03% Rb (or their mixt.). In this addition the Na is partly or completely replaced by Li. Excellent selectivity and lifetime are provided.

Abstract: Supported catalysts containing silver and alkali metals, for the preparation of ethylene oxide from ethylene and oxygen in the gas phase, are prepared or regenerated by modifying, respectively, a new or spent supported catalyst which already contains metallic silver and may or may not contain the light alkali metals lithium and/or sodium and, where a spent catalyst is concerned, also contains the heavy alkali metals potassium, rubidium and/or cesium, with a solution containing the heavy alkali metals, the modifier solution used containing (a) a surfactant and/or a reducing agent, in the case of the preparation of a new catalyst or (b) a surfactant, in the case of the regeneration of a spent catalyst.

Abstract: Alpha-Al2O3-supported Ag catalysts for ethylene oxide prepn., from C2H4 and O2, contain less than 0.001 wt.% alkali-soluble Si cpds. (I), calculated as SiO2 and w.r.t. total catalyst wt. Long catalyst life can be achieved without loss in activity and selectivity.
