Four product quality improvement methods for synthesis gas to ethylene glycol are reviewed,including liquid phase hydrogenation,NaOH addition,additive agent and ion exchange resin adsorption.The action principles and effects of the four methods were discussed.The performance of hydrogenation cata-lyst is the basis for improvement of ethylene glycol product quality.The performance of liquid phase hydrogenation catalyst should be improved further to simplify the production process.The engineers and technicians can consult the methods of improving product quality in this paper.
