| titleOfInvention | Method and apparatus for manufacturing alumina |
| abstract | In the present invention, the starting aqueous slurry containing seed alumina hydrate is introduced into a circulation system, and the aqueous slurry is circulated to recover the starting aqueous slurry, and an aqueous aluminum salt solution and a neutralizing agent solution are added to the purified aqueous slurry, and the pH value is Alumina is prepared by a process that mixes together in 6 to 11 to contain the alumina hydrate formed before the aqueous slurry is recovered to the starting slurry. The production of alumina consists of a vessel equipped with a shaker and containing an aqueous slurry, a circulator capable of guiding the aqueous slurry outwards and circulating the externally-induced aqueous slurry and allowing it to be returned to the container, and a circulating aqueous slurry, an aqueous solution of aluminum and a neutralizing agent. An additional mixer for mixing the aqueous solutions together, wherein the purifying device described above adds an aqueous solution of aluminum salt to the circulating aqueous slurry and a second liquid adding device for adding the neutralizing aqueous solution to the purified aqueous slurry; Together in an alumina manufacturing apparatus installed in an aqueous slurry feedback zone. In the present invention, a porous alumina, such as alumina, which provides an excellent carrier of the hydrotreating catalyst, and a porous oxidized compound mainly composed of alumina can be provided, and the porous alumina prepared by the present invention and a porous oxidized compound mainly composed of alumina Is simple but manufactured with high productivity and can form shaped articles of high mechanical strength. |
