摘要: 在实验室选择具有良好化学惰性的气相法SiO2为载体,加入一定量的改性剂以及氧化铁为主的复合氧化物作为活性组分,采用浸渍法制备出选择性氧化催化剂LS-06。试验结果表明,在反应温度为200 ℃、气体体积空速为1 600 h-1、H2S体积分数为1%~3%的条件下,LS-06催化剂上H2S选择性氧化的转化率可达95%以上,硫磺产率为90%以上。1 000 h长周期对比试验结果表明,LS-06催化剂具有良好的活性及活性稳定性,综合性能达到国外同类催化剂水平。

Abstract: The selective oxidation catalyst LS-06 was prepared by impregnation method using chemical inertness fumed silica as a carrier and the composite oxide of modifier and iron oxide as active component.The results of laboratory evaluation showed that the selective oxidation conversion rate of hydrogen sulfide over the catalyst is more than 95% and the sulfur yield is more than 90% at reaction temperature of 200 ℃,the gas volume space velocity of 1 600 h-1 and the volume concentration of hydrogen sulfide of 1%—3%.The results of 1 000 h long cycle contrast experiment indicated that the LS-06 catalyst has a good activity and stability,and the comprehensive performance reaches the same level as foreign similar catalyst.
