摘要：

Ni/Cu/Al/Fe hydrotalcite-like compounds (HTlcs) were synthesized by a co-precipitation method. The catalytic activity of the reduced HTlcs in glucose hydrogenation was investigated. The effects of preparation methods and activation treatments on the performance of the obtained catalysts were discussed in detail. The non-calcined catalyst which was reduced at 923 K in a H-2 flow showed higher activity for glucose hydrogenation. The conversion of glucose and selectivity to sorbitol on Ni4.63Cu1Al1.82Fe0.79 at 398 K were 93.6 and 94.2%, respectively. The reactivated catalyst through acetone elution was found to show fairly good activity in recycling experiments.
