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: A novel catalyst, esp. for use in the dehydrogenation of satd. hydrocarbons to give olefins, comprises (a)50-95 wt.%, calculated as Fe2O3, of one or more Fe cpds.; (b) 3-50 wt.% calculated as K2O, of a K cpd.; (c) 0.1-20 wt.%, calculated as Cr2O3 or Al2O3, of one or more Cr or Al cpds.; (d) 0.1-20 wt.%, calculated as MoO3 or WO3 of one or more Mo or W cpds.; (e) 0.1-20 wt.%, calculated as V2O5 or P2O5, of one or more V or P cpds.; (f) 0.1-5 wt.%, calculated as Li2O, of a Li cpd.; and (g) other components obtd. when the Fe and K are predominantly or wholly introduced in the form of the water-insol. K ferrite K2Fe22O34. USE/ADVANTAGE - The catalyst is in ready-to-use form esp. for the prepn. of styrene from Et benzene, giving high activity and high selectivity simultaneously, and being self-regenerating under the reaction conditions, such properties being attained by predominantly or solely introducing the Fe and K as the ferrite K2Fe22O34.

Abstract: A silver catalyst containing lithium and cesium as promoters for the direct oxidation of ethylene with oxygen to give ethylene oxide is applied to a porous carrier and essentially consists of alpha -alumina and contains certain amounts of soluble calcium, aluminum, potassium and sodium salts. The carrier has a BET surface area of from 0.4 to 0.8 m2/g, a pore volume of not less than 0.45 ml/g, the pores being equally accessible to cold and warm water, a bulk density of less than 700 kg/m3 and a shape which, in the reactor, provides a geometrical surface area of not less than 600 m2/m3, on which more than 13% by weight of silver are applied as active component and more than 115 kg of silver are available per m3 of reactor, and from 100 to 300 ppm by weight of lithium and from 200 to 600 ppm by weight of cesium are present as promoters. A process for the preparation of the silver catalyst and its use for the oxidation of ethylene are described.
