چکیده انگلیسی
The effect of replacement of γ-Al2O3 by La2O3 was studied on Ni catalysts for hydrogen production via acetic acid steam reforming. The La/(La + Al) weight ratio ranged from 0 to 1 in the catalyst support prepared by co-precipitation method. Over the Ni/La-3Al catalyst (the La/(La + Al) weight ratio at 0.25), the carbon conversion and hydrogen yield reached 100% and 72.72%, respectively, which was obviously higher than other catalysts at 700 °C, S/C = 1 and LHSV = 10 hâ1. The effect of S/C, LHSV and stability test were studied in detail over Ni/La-3Al catalyst, whose high activity maintained for more than 30 h.
