Abstract
In a process for producing ethylene oxide by the partial oxidation of ethylene by means of a gaseous mixture containing 25-70% by volume of oxygen in the presence of a silver-containing catalyst, the process is carried out in two reaction zones in series, with purging from and recycling to each, the mixture in each having an oxygen concentration 1-10% by volume, a concentration of oxygen not in excess of 10% by volume, a concentration of halogenated inhibitor in the range of 0.0001 to 100 p.p.m. by weight, a concentration of methane and/or ethane in the range of 0.001 to 40% by volume, a reactor temperature in the range of 150-400 DEG C., a reactor pressure in the range of 50 to 650 p.s.i.g., a flow rate in the range of 150-1500 standard cubic ft. per hour per zone, an average zone diameter of 0.5-2.0 inch, and a zone length of 5-40 ft., the conditions being controlled to provide in the first zone a concentration of ethylene in the range of 5-30% by volume, a selectivity in the range 65-75% and a conversion in the range of 10-30%, and in the second zone a concentration of ethylene in the range of 1-5% by volume, a selectivity of 60-70% and conversion of 30-90%, and an ethylene oxide concentration in the exit gases of either stage of 0.3-5.0% by volume.
