- •
The increase of yttrium loading decreased the acidity of Ni/Al2O3
Y2O3 catalysts.- •
The increase of Y loading favored Ni reducibility at lower temperatures.
- •
The Y effect is more noticeable at high water to ethanol molar ratios.
- •
The highest hydrogen production is observed in the 15%wt. Y2O3 containing catalyst.
