Alumina, preparation method thereof and catalyst containing alumina |
| abstract |
The invention provides alumina, which is subjected to air roasting treatment at 900 ℃ for 1-6h, and the total pore volume measured by low-temperature nitrogen adsorption is not less than 1.25cm 3 (ii) in terms of/g. The invention also provides a preparation method of the alumina and a catalyst using the alumina as a carrier. The alumina prepared by the method has better high temperature resistance and larger pore volume. The catalyst prepared by using the catalyst as a carrier has better activity and correspondingly prolonged service life. |
