摘要
采用微型连续流动式固定床反应器，考察了几种炼油厂瓦斯脱硫化氢催化剂的性能。结果表明：以Ｖ２Ｏ５与Ｂｉ２Ｏ３为活性组分，ＴｉＯ２与Ａｌ２Ｏ３为载体的催化剂，在常压，１８０℃，ＧＨＳＶ为１０００ｈ－１，Ｏ２／Ｈ２Ｓ（物质的量比）为１：（０．８～１．２）的条件下，试验效果最佳。当进料中硫化氢的质量浓度低于２ｇ／ｍ３时，单程运转１４０ｈ后，硫化氢的转化率仍达８５％以上。
The performance of several catalysts for selectively oxidating H 2S to S in oil refining gas stream is studied with continous flowing micro fixedbed reactor. The excellent one is the catalyst composed of V 2O 5, Bi 2O 3 and TiO 2, Al 2O 3 at atmosphere, 180 ℃,GHSV=1 000 h -1 and O 2/H 2S of amount of substance ratio 1∶(0.8～1. 2). The conversion of H 2S is over 85% through a single period of 140 hour run, as the capacity of H 2S in feeding stream below 2 g/m 3.
