摘要： A method for improving the quality of ethylene glycol products, which mainly solves the technical problem of low UV-light transmittance of the ethylene glycol products present in the prior art. The method successfully solves the problem by use of the technical solution wherein the ethylene glycol raw material and hydrogen are passed through a rotating packed bed reactor loaded with solid oxide catalyst at a temperature of about 20 to about 280 ° C., a pressure of about 0.1 to about 4.0 MPa, a space velocity of about 0.2 to about 100.0 hr−1 and a molar ratio of hydrogen to ethylene glycol of from about 0.01 to 40:1, and ethylene glycol is obtained after the reaction. The solid oxide catalyst is at least one of copper-based, nickel-based and palladium-based catalysts, and the rotation rate of the rotating packed bed reactor is about 300 to about 5000 rpm.
