| Abstract: | Titania-alumina of various compositions (atomic ratios: 1/8, 1/1, 8/1) were prepared by coprecipitation. The active components were impregnated on Al2O3, TiO2-Al2O3 and TiO2. The abilites of sulphur-resistance of supports and catalysts were studied with various techniques including BET, IR etc. It was found that the amount of SO2 absorbed changed with the variation of support compositions.The stronger the surface acidity of support was,the smaller the amount of SO2 absorbed. Mechanism of sulphur-poisoning was discussed. |
