Abstract: C2-C4-olefins are prepared by catalytic conversion of methanol and/or dimethyl ether in the presence of a zeolite catalyst at elevated temperatures, by a process in which the catalyst used is a pure borosilicate zeolite which has been tableted or extruded without a binder and treated with hydrofluoric acid and hydrochloric acid. The treatment of the catalyst with hydrofluoric acid is carried out using 0.001-1N HF, and that with hydrochloric acid is carried out using 3-25% strength acid. The time-on-stream of the catalyst is improved.

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.
