加氢富气干法脱除硫化氢催化剂的研究

Research on Catalyst for Hydrogen Sulfide Removal in Hydrotreating Offgas Dry Process

以γ -Al2 O3 为载体 ,以钒、铋为活性组分 ,镧、钠等为助剂制成用于干法选择氧化脱除加氢富气中硫化氢的催化剂。其最佳反应条件是 :反应温度 180℃ ;空速 14 0 0h-1;常压。在该反应条件下加氢富气中H2 S的平均转化率为 93% ,平均选择性为 90 5 %。小试及工业放大试验结果表明该催化剂具有寿命长、性能稳定、再生效果好等优点 ,适用于脱除加氢富气中的硫化氢。

A γ-Al 2O 3 catalyst containing V,Bi,La and Na was used to selectively oxidate H 2S in hydrotreating play offgas to elemental sulfur. The result shows that this catalyst has superior activity and selectivity to elemental sulfur. In a 1000 hours run, the conversion of H 2S was 93%, and the selectivity to sulfur was 90 5% in average.
