Abstract
Process for producing ethylene oxide by the partial oxidation of ethylene by a gaseous mixture of oxygen containing 25 to 70% oxygen in the presence of a catalyst containing silver, characterized by the improvement that means operating with two reaction zones, in series, purging and re-cycling each cycle, and each with an oxygen concentration of the order of 1 to 10%, a concentration of carbon dioxide of the order of 0.1. at 10%, a concentration of halogenated inhibitors in the order of 0.0001 to 100 parts per million, a concentration of hydrocarbons lower in the order of 0.001 to 40%, a reactor temperature of the order of 150 to 400 degrees centigrade, a reactor pressure of the order of 3.52 to 45.70 kg/cm2, a fluidity in the order of 4.248 to 42.84 m3, under normal conditions, hour per elongated zone with the diameter of the average zone of the order of 12 , 7/to 50.8 mm, and a zone length of 1.524 to 12, 192 m. controlling the particular combination of conditions for preparing in the first zone an ethylene concentration of the order of 5 to 30%, a selectivity of the order of 65 to 75% and a conversion of the order of 10 to 30%, and, in the second zone , an ethylene concentration of the order of 1 to 55%, a selectivity of the order of 60 to 70% and a conversion of the order of 30 to 90%, and a concentration of ethylene oxide in the exhaust gases for each stage of the order from 0.3 to 5.0%.
