摘　　要：在不同温度下煅烧以沉淀方法制得的La(OH) 3 ,研究锻烧产物及其催化活性 ,发现LaOOH在 380～ 5 0 0℃范围内生成。此研究结果对降低还原脱硫的反应温度有重要意义。单纯的La(OH) 3 粉末催化效果不明显 ,用γ -Al2 O3作载体 ,采用浸泡法制得的Ce-La/Al2 O3Lanthanum hydroxide calcined in different temperature range and its activity was studied.Temperature range of LaOOH was in 380～500℃.It is significant to reduce the temperature of the catalytis reduction of SO 2 to elemental sulfur by using pulse discharge plasma.The activity of pure La(OH) 3 powder was almost ineffective.Using γ-Al 2O 3 as carrier,doped ceria catalyst was active for the SO 2 reduction.
