China Manufacturer for Aluminium Oxide - What is the application of pseudo boehmite? – Ton Year Detail:
What is the application of pseudo boehmite?,
Pseudo Boehmite,
Product Performance:
A white gel (wet) or powder (dried), odorless, tasteless and nontoxic. It is a thixotrope with the characters of high purity crystalline phase, EXCELLENT GELATION and strong caking property.
It is a cement of the cracking catalyst for semi-synthetic rare-earth Y molecular sieve, a cement in aluminum silicate refractory fiber, a catalyst in making ethylene by alcohol dehydration and in making epoxy ethane. It also can be used as raw material for activated alumina and other aluminates.
Pseudoboehmite Application:
1. FCC and hydrogenation catalyst carrier.
2. Cement in aluminum silicate refractory fiber.
3. Catalyst in making ethylene by alcohol dehydration and in making epoxy ethane.
4. Used as raw material for activated alumina and other aluminates.

Analysis of the advantages of macroporous pseudo-boehmite
Advantages of product indicators
1. The impurity content is more than 10 times lower than other domestic manufacturers. The content of Na2O, SiO2, Fe2O3 is lower than 50PPM, and the contents of Ca, Mg, SO42-, Cl-, Pb, Cd, V, etc. are lower than 10PPM.
2. The hole volume and surface area are larger and more stable than other manufacturers. In particular, downstream customers’ pore volume and specific surface area after molding will not be greatly reduced, and the strength after molding without relying on other binders is very high, which is beyond the reach of other domestic manufacturers.
Our company’s raw materials are all purchased from high-purity materials. The entire process adopts stainless steel or plastic-lined equipment and pipelines, two-stage reverse osmosis water equipment, three iron removal processes and three backwashing processes to ensure high purity and no pollution.
Second quality stability measures
Our company’s process is equipped with cooling and heating equipment to ensure that the temperature in the process is constant. Equipped with complete laboratory equipment and personnel, the entire process of the production process inspection and monitoring, and regular calibration with downstream customers, universities and other institutions to ensure the control of the production process and the stability of product indicators.
