TL;DR: The catalysts of attractive activities for use in the oxidation of ethylene to ethylene oxide comprise silver supported on a porous heat resisting support, a group VI A transition metal, potassium, rubidium and/or cesium and sulphur as discussed by the authors.

TL;DR: Olefine oxides are produced by contacting an olefine with oxygen in the presence of a silver containing catalyst and a chlorine-containing reaction modifier; the performance of the catalyst is improved by contacting it with a nitrate or nitrite forming substance for example nitric oxide as mentioned in this paper.

TL;DR: A gas stream from a reaction in which ethylene oxide is produced by reacting ethylene with oxygen which gas stream comprises oxides of nitrogen and steam is cooled to condense water, condensed water is removed, and then recovered from the gas stream as mentioned in this paper.

TL;DR: In this article, the authors proposed a porous heat resisting support which comprises at least 0.003 gram equivalents of rubidium and/or cesium chemically absorbed on the surface of the support per kilogram of the total catalyst.

TL;DR: The catalysts of attractive activities for use in the oxidation of ethylene to ethylene oxide comprise silver supported on a porous heat resisting support, a group VI A transition metal, potassium, rubidium and/or cesium and sulphur as mentioned in this paper.
