Pseudo boehmite
Pseudo boehmite
This product is odorless, white sandy powder. Has high pureness, 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, 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.
The following is the technical indicators for powder:
Brand | Pore Volume | BET ≥m2/g | L.O.I % | Al2O3 % | SiO2 ≤% | Fe2O3 ≤% | Na2O ≤% | Al2O3·3H2O ≤% | Bulk Density ≤g/cm3 |
HF-P-5 | 0.3-0.6 | 260 | 18-22 | 68-72 | 0.3 | 0.01 | 0.08 | 3 | 0.6-0.8 |
HF-P-10 | 0.85-1.05 | 360 | 18-22 | 68-72 | 0.03 | 0.01 | 0.008 | 3 | 0.2-0.3 |
Application:
1. Catalyst carrier (used as FCC and hydrogenation);
2. Cement (used in cracking catalyst for semi-synthetic rare-earth Y molecular sieve, aluminum silicate refractory fiber);
3. Catalyst (used as making ethylene by alcohol dehydration and making epoxy ethane);
