Abstract: The advances in ethylene oxide and ethylene glycol technology were summarized. The characteristics of different types of silver catalyst，their industrial applications and development trends were analyzed. The progress of production technology of ethylene oxide was reviewed，including operation technology of highly selective silver catalyst in the early stage and aging stage，simplified process of ethylene oxide absorption and desorption sections，technology of increasing ethylene oxide purity and reducing equipment corrosion，catalytic hydration technology，technology of refining ethylene glycol products，and development of new types of ethylene oxidation reactor. The development of ethylene glycol via syngas，its industrial application and existing problems were summarized. The suggestions about domestic silver catalyst development，complete set of technology development and commercialization of ethylene glycol process via syngas were presented.
