Abstract
A process for the production of ethylene oxide, which comprises effecting ethylene oxidation with oxygen in the presence of carbon dioxide, the components being present in a volume ratio of 5-15 ethylene to 10-15 oxygen to 75-85, carbon dioxide. The process is effected at a temperature of from 290.degree. to 300.degree. C. and a pressure of from 35 to 50 atm. The components form an upward flow moving at a speed of from 10 to 12 m/sec. The oxidation is carried out in the presence of a silver catalyst on a carrier likewise forming an upward flow which moves at a speed of from 4 to 6 m/sec. The reaction mixture resulting from the oxidation procedure contains the desired product, the unreacted ethylene and the unreacted oxygen. The desired product is recovered from the mixture.
