| 摘 要： | 针对环氧乙烷生产中的含乙烯排空气的处理，在试验了数种吸附剂的基础上，筛选了活性炭吸附剂。它对乙烯具有良好的吸附选择性，并能有效地脱除氩气，及部分ＣＯ２。经条件试验表明，该吸附剂对乙烯的回收率＞９０％，Ａｒ的脱除率＞８９％，ＣＯ２的脱除率＞２１％。且过程简单、经济，具有良好的工业应用前景。

| Abstract: | Adsorption method is used to recover ethylene,and remove argon and carbon dioxide from a vent gas stream in the production of ethylene oxide by direct oxidation It is found that activated carbon,specially activated carbon G is highly selective to ethylene It can recover 91% of ethylene,and at the same time remove 89% of argon and 21% of carbon dioxide from recycling stream by pressure swing adsorption It can be used in ethylene oxide factory to reduce the consumption of ethylene |

| Keywords: | adsorption activated carbon ethylene argon carbon dioxide |
