摘要
介绍了非晶态合金催化荆的结构特点,比较了载体、添加金属或稀土元素等改性对催化剂热稳定性能和催化性能的影响。分析了镍基非晶态催化剂硫中毒的机理,综述了载体以及添加稀土元素对催化剂抗硫性能的影响,并对非晶态合金催化剂的研究和应用前景进行了展望。
The characteristics of the amorphous alloy catalysts and the effects of supports and addition of metals or rare earth metals on their thermal stability and catalytic properties were reviewed. The sulfur poisoning mechanisms for amorphous nickel-based alloy catalyst and the effects of supports and addition of metals or rare earth metals on sulfur tolerance of the catalysts were discussed. The prospects for researches and application of the amorphous alloy catalyst were outlined.
