Abstract: Ethylene glycol is widely used in chemical industry. Compared with traditional petroleum- based production method, biomass based processes not only feature abundant feed supply and flexible product portfolio, but also act as promising alternatives for additional ethylene glycol product. This review is focused on catalysts and reaction mechanism of sugar alcohol selective hydrogenolysis, direct catalytic conversion of cellulose, biomass fermentation and ethylene glycol production via glyoxal as fermentaion product. It is suggested that more efforts should be made to improve biomass pre-treatment procedure, develop efficient and stable catalysts and upgrade product quality.

Key words: biomass, sugar alcohol, cellulose, fermentation, ethylene glycol
