- •
La species addition stabilizes γ-Al2O3 towards sintering and loss of surface area.
- •
Strongest acido-basic couples are obtained in low loading La2O3/Al2O3.
- •
5%La2O3/Al2O3 is equally or more selective to ethylene at high ethanol conversion.
- •
5%La2O3/Al2O3 reduces ethylene overconversion products.
