Ethylene carbonate can be formed from ethylene glycol and CO2 over CeO2-ZrO2 catalysts. The activity of ethylene carbonate formation was much dependent on the catalyst composition and calcination temperature, and it is found that CeO2-ZrO2 (Ce/(Ce+Zr)=0.33) calcined at high temperature (1273 K) is very effective catalyst. The by-product of diethylene glycol was formed at higher reaction temperature than 423 K, however, at lower temperature, diethylene glycol was not detected.
