A kind of titanium-doped γ-alumina and preparation method thereof |
| abstract |
The invention discloses a titanium-doped γ-alumina and a preparation method thereof. The titanium-doped γ-alumina has the following properties: titanium dioxide is uniformly dispersed in the γ-alumina bulk phase, the size of titanium element clusters is greater than 2.5 nm and the Below 5.0nm; the total porosity is 60%-85%, the macropore diameter is 100-1000nm, and the proportion of macropores to the total porosity is 40%-90%; the macropore distribution is uniform and three-dimensional through; the ratio of macropore wall thickness to pore size size is 0.5‑4.5; the lateral crushing strength is 8‑25N/mm. In the present invention, titanium-doped γ-alumina is prepared by a sol-gel method. The product has three-dimensional macropores and high mechanical strength of the material, which can meet the strength requirements of existing heterogeneous catalytic reactions and can be used as a good carrier for catalysts. |
