研究了La 2 O3取代γ-Al 2 O3对Ni催化剂醋酸水蒸气重整制氢性能的影响。在通过共沉淀法制备的催化剂载体中，La/（La + Al）重量比在0至1范围内。在Ni/La-3Al催化剂（La/（La + Al）重量比为0.25）上，在700 °C、S/C = 1和LHSV = 10 h-1时，碳转化率和氢产率分别达到100%和72.72%，明显高于其他催化剂。在Ni/La-3Al催化剂上，详细研究了S/C、LHSV和稳定性对催化剂活性的影响，其高活性可保持30 h以上。
The effect of replacement of γ-Al2O3by La2O3was 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 h−1. 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.
