摘要
研究了碱金属助剂对Pt/γ Al2O3催化剂选择性氧化富氢气氛中CO性能的影响。结果表明,碱金属助剂的引入对Pt/γ Al2O3的催化性能有不同程度的改变,其中添加Na和K后,能明显提高低温下的CO转化率。
The effects of alkali metal promoters on the catalytic performance of Pt/γ-Al_2O_3 for preferential oxidation(PROX) of CO in hydrogen-rich stream were studied. The results showed that doping of alkali metal promoters had different influences on the performance of Pt/γ-Al_2O_3 catalyst. The doping of Na and K promoters increased the conversion of CO at low temperature.
