| 英文摘要 | the structure and surface acid-base properties of al(2)o(3)-, cao-, mgo-, and kno(3)-modified mgo catalysts were characterized by x-ray diffraction, thermogravimetry, nh(3) temperature-programmed desorption, and co(2) temperature-programmed desorption. the catalysts were applied to catalyze the gas-phase transformation of propylene glycol in a fixed-bed reactor. the results indicated that the catalytic performance of these catalysts significantly depended on the surface acid-base properties. main products detected were propionaldehyde and acetone on al(2)o(3), acetol on mgo, and acetone and allyl alcohol on cao. however, the mgo catalyst modified with kno(3) remarkably enhanced the selectivity for propylene oxide. a six-pathway reaction mechanism was proposed to describe the catalytic transformation of propylene glycol based on the acid-base properties and the reaction results of the catalysts. |
