| 摘 要： | 采用浸渍负载法制备了分子筛担载的钾催化剂K/Zeo(Zeo = ZSM-5,Y),研究了分子筛及K/Zeo对乳酸制备2,3-戊二酮的催化活性.对催化剂进行了X-光衍射和低温氮气吸附表征.结果表明,改性过程导致分子筛的骨架结构在一定程度上的破坏,比表面积、孔体积减小,而孔径增加.催化剂反应性能评价及碳平衡研究表明,与改性...

| Abstract: | A series of KNO3 modified zeolite catalysts(K/Zeo,Zeo = ZSM-5,Y)were prepared in impregnation method and employed in the conversion of lactic acid to 2,3-Pentanedione(PDO).The characterizations of XRD and low-temperature N2-physisorption indicated that the process of KNO3 modification damaged to some extent the framework of zeolites,resulting in the decrease of specific surface area and pore volume but the increase of the pore size of the zeolites.The catalytic performance evaluation and carbon balance exam... |
