1. Description of proposed boehmite product: This product is non-toxic, tasteless and odorless. The wet product is white colloid and the dry powder is white powder. The pore size distribution is uniform, the volume is large and the water absorption is good. It has high radial purity, good molding performance and thixotropic gel properties. The product has good dispersibility, is easy to dissolve in strong acid and alkali solution, and has good molding performance.
2. Packaging and storage of pseudo boehmite: pseudo boehmite is packed in woven bags. Store in a cool, well ventilated and dry warehouse.
3. Main uses of proposed boehmite:
This product is mainly used as raw material of catalyst support activated alumina, such as raw material of hydrogenation catalyst, support of hydrogenation catalyst and oxychlorination catalyst.
It can also be used as molding binder for zeolite and silicate refractory fiber products, such as binder for semi synthetic rare earth Y zeolite cracking catalyst.
The product is a good raw material for the production of various aluminum salts. After molding, it can be used as desiccant, adsorbent and catalyst carrier with different shapes.
1. Optimizing the selection of process equipment and washing and filtration with high-efficiency fixed chamber vacuum belt filter are the key to reduce the fresh water consumption in the production of pseudo boehmite.
2. The third washing solution is used for the batching of sodium aluminate solution to reduce the external displacement and improve the utilization efficiency of new water. It is an important measure to reduce new water consumption.
3. The main way to reduce the consumption of new water is to appropriately increase the temperature of washing hot water, formulate a reasonable process system and adopt a segmented cooling system.
Pseudo boehmite is a kind of pseudo boehmite with incomplete colloidal crystallization. Products 1, non-toxic, 2, tasteless, 3, odorless, 4, crystalline phase high purity, 5, good solubility, 6, strong adhesion, 7, with thixotropic gel characteristics.
