采用固-气反应体系,研究了一系列负载型碱金属盐催化剂对生物质1,2-丙二醇脱水环氧化制备环氧丙烷(PO)的催化作用。通过X射线衍射和CO2程序升温脱附研究了载体、碱金属盐中的阳离子和阴离子以及煅烧温度对产物的影响。结果表明,碱性较弱的催化剂具有较高的PO产率。在KNO 3/SiO2催化剂上,在400 °C和常压下,PO的最高收率为58.2%。催化剂在550 °C空气中焙烧后可重复使用。
A series of supported alkali metal salts were investigated as catalysts to produce propylene oxide (PO) from biomass-derived 1,2-propanediol via dehydrative epoxidation in a solid–gas reaction system. The effects of supports, cations, and anions in the alkali metal salts and calcination temperature were investigated by X-ray diffraction and CO2-temperature-programmed desorption. The results indicate the catalysts with relative mild basicity having higher yields of PO. The highest yield of PO is 58.2% from reactions at 400 °C at an atmospheric pressure over KNO3/SiO2. In addition, the catalyst could be reused after calcination in air at 550 °C.
