Catalyst for preparing nonene and dodecene by propylene oligomerization and its preparation method and application |
| abstract |
The invention discloses a catalyst for preparing nonene and dodecene by oligomerization of propylene and a preparation method and application thereof. The method includes the following steps: a) dispersing a zirconium dioxide precursor, a silicon dioxide precursor and a surfactant in a solvent, and performing a precipitation reaction to obtain a slurry, the amount of the silicon dioxide precursor and the zirconium dioxide precursor added Satisfy that the mass ratio of silica and zirconia is 1:20-1:0.5; b) aging the slurry to obtain a precipitated product. After molding and calcining, a catalyst is obtained. The invention enables the catalyst to have higher selectivity in the application of propylene oligomerization to prepare nonene and dodecene, and at the same time, it can also have higher stability and less corrosivity. |
