挤条成型Mg/Sn/W复合氧化物催化剂制备及性能表征
Synthesis and characterization of extruded composite oxides Mg/Sn/W and its catalysis performance in cyclohexanone to ε-caprolactone
摘要
Abstract
The forming process of Mg/Sn/W composite oxide catalysts was studied.The characteristics of the catalysts were determined by using X-ray diffraction (XRD),surface detection system (BET) and scanning electron microscopy (SEM).The effects of different binders,content of binder,different pore-forming agent,content of pore-forming agent and calcination temperature in the preparation process were investigated.Thus the optimum conditions of Mg/Sn/W composite oxide catalyst forming process were determined:the content of proper binder pseudoboehmite sol was 15％ and the content of proper activated charcoal was 5％.The drying temperature was 80 centigrade,and the baking temperature was 550 centigrade with the baking time of 3 hours.Under this condition the reaction selectivity is 86.57％.关键词
