Abstract
The present invention relates to catalyst field, discloses a kind of aging method of continuous ageing reactor and aluminium hydroxide.Continuous ageing reactor provided by the invention includes reactor body, the feed inlet (3) for being arranged at the reactor body top and the discharge port (10) for being arranged at the reactor body lower part, demarcation strip (14) is provided with the reactor body inner wall, the reactor body is divided into more than 2 aging chambers by the demarcation strip (14)；Agitating shaft (12) is provided with the middle part of the reactor body, corresponding to each aging chamber on the agitating shaft (12) is respectively arranged with blade (13).Pass through continuous ageing reactor provided by the invention and the aging method of aluminium hydroxide, it is possible to achieve the continuous ageing of aluminium hydroxide slurry, prepares high purity pseudoboehmite.
Description
Technical field
The present invention relates to catalyst field, and in particular, to a kind of aging side of continuous ageing reactor and aluminium hydroxide
Method.
Background technology
Boehmite is that a kind of particle is tiny, crystallization is imperfect, has the aluminium hydroxide of thin fold lamella, its is aqueous
State is thixotropy gel, has the characteristics that specific surface area height, large pore volume, the high boehmite of crystalline phase purity is that a kind of performance is excellent
Good catalyst carrier.Boehmite can not only improve the activity of catalyst, but also can carry as catalyst carrier for hydrgenating
The intensity of high catalyst.The direct phases of physico-chemical property such as the performance of boehmite and its specific surface area, pore structure, crystallite dimension
Close, therefore, it is necessary to its physico-chemical property be adjusted, to reach application demand in the preparation process of boehmite.Wherein
A kind of most often applied means for adjusting physico-chemical property are to carry out burin-in process to aluminium hydroxide slurry, so that changing it compares surface
The physico-chemical properties such as product, pore structure and crystallite dimension.
At present, the main method of boehmite is prepared by choline aluminium Hydrolyze method, alum pyrolysismethod, aluminium carbonate ammonium
Pyrolysismethod and aluminium alcoholates method.And in addition to aluminium alcoholates method, the boehmite of other methods preparation, purity is difficult to be guaranteed, Wu Faman
Requirement of the sufficient catalyst carrier to boehmite purity.The step of aluminium alcoholates method prepares boehmite be：First by alcohol and metal
Aluminium reacts generation aluminum alkoxide at a certain temperature, and aluminum alkoxide hydrolyzes generation alcohol and aluminium hydroxide slurry, passes through again afterwards again
Different physico-chemical property boehmites are made in aging process.
For hydroxide slurry ageing process, industrial generally use autoclave aging reaction device, by hydroxide material
It is added in autoclave aging device, maintains certain temperature, pressure to carry out burin-in process, the shortcomings that this processing mode is aging
Process is intermittent operation, and production efficiency is relatively low, simultaneously because batch is handled, the aging condition of every batch of is difficult to keep complete
It is homogeneous, cause the physical property of product fluctuation larger.There is presently no the relevant report of aluminium hydroxide slurry continuous ageing.
The content of the invention
The object of the present invention is to provide a kind of continuous ageing reactor, which can realize the continuous of aluminium hydroxide slurry
Aging, can be used for preparing high purity pseudoboehmite.
To achieve these goals, the first aspect of the invention is to provide a kind of continuous ageing reactor, the reactor
Including reactor body, it is arranged at the feed inlet on the reactor body top and is arranged at going out for the reactor body lower part
Material mouth, is provided with demarcation strip on the reactor body inner wall, the reactor body is divided into more than 2 by the demarcation strip
Aging chamber；Agitating shaft is provided with the middle part of the reactor body, each aging chamber is corresponded on the agitating shaft and is respectively arranged with paddle
Leaf.
The second aspect of the invention is to provide a kind of aging method of aluminium hydroxide, and this method is anti-in above-mentioned continuous ageing
