Low Sodium Pseudo Boehmite
Low Sodium Pseudo Boehmite is white gel or powder. It is odorless, tasteless and non-toxic. It has high purity of crystalline phase, good gel property and strong caking property. The molecular sieve 5A can adsorb any molecule less than the aperture, generally known as a calcium molecular sieve.
Description
Description
This product is made from sodium aluminate solution and carbon dioxide gas through a special rubber process. With its good stability and excellent physical and chemical properties, the product is widely used in the production of various petroleum distillate hydrogenation catalysts, coal tar hydrogenation catalysts, cracking gasoline hydrogenation fine catalysts, and chemical catalysts. Due to its lack of chloride and sulfur ions, this kind of aluminum hydroxide is often used in the research and production of various organic synthesis catalysts.
Features
1. Low Sodium Pseudo Boehmite has the advantages of high purity of crystalline phase, good gel property and strong caking property.
2. This product is often used in the field of hydrogenation fission, residual oil hydrogenation and hydrotreating catalyst.
3. It is often used in γ- Al_2o_3 and α- The preparation of Al2O3 can also be used as a catalyst carrier for petroleum production.
4. It is a methanation catalyst carrier, a vehicle tail gas treatment carrier, and a semi-synthetic rare earth Y molecular sieve cracking catalyst.

This sieve is absorbed by material at the molecular level. It can absorb up to 22% of the water from its own body weight. The adsorption principle is similar to chromatography, but it does not change the molecular combination of matter.
1,Natural gas drying, desulfurization and removing carbon dioxide;
2,Nitrogen and oxygen separation, nitrogen and hydrogen separation, the production of oxygen, nitrogen and hydrogen;
3,Oil stripping and separating normal hydrocarbons from branched and cyclic hydrocarbons.
4,Remove water: depending on the pressure, temperature and water content of regas.Generally, the 200~350℃ dry gas is in 0.3~0.5kg/cm. At pressure, the outlet temperature is cooled at 1 ~ 4 hours to 110~180℃..
5,Remove the organic matter: replace the organic matter with water steam, and then remove the water parts.
6,Storage: room temperature, relative humidity not more than 90%; should not be directly exposed to air; avoid water, acid and alkali.
7,Packaging: cardboard bucket or carton packaging.
Note: Avoid the molecular sieve exposure directly to the air.
