摘　　要：采用共沉淀法制备了含铝、钛、硅等元素的EKl01硫化氢选择性氧化催化剂，并讨论了催化剂在各使用工艺条件下的性能。实验表明，催化剂在常压，230℃～310℃，空速〈2000h～，进口硫化氢体积分数1．2％～4．4％、氧硫比0．94～1．04，二氧化碳体积分数65％～92％的条件下转化率和选择性分别可达97％和98％以上，硫磺回收率可达95％以上。催化剂经500h稳定性试验后仍具有稳定的转化率和选择性。EK101 hydrogen sulfide selective oxidation catalyst containing elements like aluminum , titanium and silicon was prepared with coprecipitation method, the performances of the catalyst in various process conditions are discussed herein.The result presents that under the conditions of atmospheric pressure, 230℃～310℃,air speed＜2 000 h -1 , 1.2%～4.4%of volume fraction of hydrogen sulfide at inlet, 0.94～1.04 of sulfur/oxygen ratio and 65%～92% of CO2volume fraction, the conversion rate and selectivity of the catalyst can reach above 97% and 98% respectively, and the recovery rate of sulfur can reach above 95%.After 500h stability test, the catalyst still possesses stable conversion rate and selectivity.
