Abstract

1411315 Epoxidation A I GELBSHTEIN L A VASILEVICH I T FROLKINA G K BORESKOV O N DYMENT J N STEPANOV B B CHESNOKOV M G SLINKO N S UTKINA V V STROGANOVA M S AKSENOVA V A DAVYDOV I G TALAEVA O B PROSVIROVA AND I B ZAKHAROVA 19 Oct 1973 48818/73 Heading B1E [Also in Division C2] A fluidised catalyst for the oxidation of ethylene to ethylene oxide comprises silver, cadmium carbonate and/or cadmium oxide and fused alumina. Preferably the catalyst contains 9.5-76% (wt.) of silver, 0.5-4.0% of cadmium carbonate and/or cadmium oxide (calculated as cadmiums) and 20-90% of fused alumina and the alumina has a particle size of from 2 microns to 0.5 mm. The catalyst may also contain silver chloride in an amount of between 0.03 and 0.3% of the weight of the silver present. During the oxidation process there may be introduced into the fluidised bed a chloride of sodium, potassium, lithium, barium or cadmium in an amount of 0.1-5% of the weight of silver present in the catalyst.
