| titleOfInvention | eta-Al2O3Microsphere and preparation method and application thereof |
| abstract | The invention discloses eta-Al 2 O 3 Microspheres and a preparation method and application thereof. The preparation method comprises the following steps: dissolving sodium aluminate in water to prepare a sodium aluminate solution, then adding a certain amount of amide into the sodium aluminate solution, uniformly stirring to form a clear solution, and then sealing and standing for a certain time to carry out double hydrolysis to generate a white precipitate; filtering to obtain precipitate, washing, drying, and calcining to obtain eta-Al 2 O 3 And (3) microspheres. eta-Al synthesized by small experiment 2 O 3 Is microspheres assembled by nano sheets and having the average particle size of 2.45-5.80 mu m and the specific surface area of 281.4-331.4 cm 2 A pore volume of 0.24-0.28 cm/g 3 The average pore diameter is 3.4-4.2 nm, and the surface of the microsphere is smoother along with the increase of the concentration of the amide; eta-Al obtained after amplification 2 O 3 The appearance and texture properties of the microspheres are similar to those of a small experiment, and the selectivity of the catalysts in all the examples is 80.5-83.9%, so that the selectivity is not greatly different. |
