Dehydratation of bioethanol to ethylene over the oxide catalysts
AbstractThe catalytic systems without noble metal on the base of oxides of copper, chromium and cerium in the catalytic dehydration of bioethanol to ethylene were studied and compared. It was found that all the studied catalysts regardless of the nature of the metal have high efficiency at W-3000 and 6000 hr-1, T-4000C, Cethanol – 21,7 g/m3. The optimal catalyst is 3% Ce +1% La / γ- Al2O3, where the yield of the desired product - ethylene 82% at Т - 400оС and W- 6000 hr-1.
