| Abstract: | The catalysis of active carbon from residuum with chemically modified surface in the hydration of ethylene oxide (EO) to ethylene glycol (EG) was studied.Effects of surface chemical modification conditions and hydration conditions on conversion of EO and selectivity of EG were investigated.The results showed that residuum active carbon with chemically modified surface was an effective catalyst for the hydration of EO to EG. Under proper conditions,both the conversion of EO and the selectivity of EG could reach 95%. |
