碱土金属氧化物掺杂CeO_2催化1,4-丁二醇选择性脱水合成3-丁烯-1-醇
|
摘要
采用浸渍法制备了碱土金属氧化物MO(MgO、CaO、SrO和BaO)掺杂的MO-CeO2催化剂,通过X-射线粉末衍射、H2程序升温还原和CO2程序升温脱附等手段表征了催化剂的结构和表面性质,并考察其对1,4-丁二醇选择性脱水合成3-丁烯-1-醇反应的催化性能.结果表明,碱土金属氧化物掺杂未改变CeO2的萤石型结构,但可增加MO-CeO2催化剂的氧缺陷位和表面碱性位点,进而提高其催化1,4-丁二醇选择性脱水的活性和3-丁烯-1-醇的选择性.其中,CaO-CeO2催化剂表现出最优的催化性能,3-丁烯-1-醇收率达52.44%.
Alkaline earth metal oxides(MO = MgO,CaO,SrO and BaO) doped CeO2 catalysts were prepared by the impregnation method,the structure and surface properties were characterized by using X-ray diffraction,H2 temperature programmed reduction and CO2 temperature programmed desorption,and their catalytic performances of selective dehydration of 1,4-butanediol to 3-buten-1-ol were investigated.The results indicated that the cubic fluorite structure of CeO2 was not changed,however,more oxygen defects and surface basicity sites were formed,and then improved the conversion of dehydration of 1,4-butanediol and the yield of 3-buten-1-ol.Especially,the CaO-CeO2 catalyst showed the highest catalytic performance of dehydration of 1,4-butanediol to 3-buten-1-ol,and the yield of 3-buten-1-ol was 52.44%.
