Macroporous pseudo boehmite

    

Macroporous pseudo-boehmite molecular formula: AlOOH•nH 2O, n= 0. 08～0. 62, non-toxic, odorless, odorless, white powder, high purity, large specific surface area, uniform pore size distribution, water absorption Good, excellent dispersion, moderate thermal stability, and strong wear resistance. It has good molding properties and can be used as a desiccant, adsorbent and catalyst carrier of different shapes after molding.
The main purpose:
Its product γ-Al2O3 calcined at 400-900 °C is widely used as a catalyst carrier, catalyst and adsorbent in petrochemical, fine chemical and other industries; it can be obtained by calcination at 1100-1200 °C to obtain nano-scale α-Al2O3. It is used as a coating additive, high-grade ceramics, high-efficiency catalyst for petrochemical industry, sub-micron/nano-scale abrasive materials and polishing materials, cosmetic fillers and inorganic membrane materials. It is a new type of material with broad development prospects.

We can produce pseudoboehmite powder according customers requirement

Small pore pseudo boehmite

This product is non-toxic, odorless, odorless, white gelatinous (wet) or powdery (dry), high purity of crystal phase, good molding performance, and characteristic of thixotropic gel.
This product is mainly used as a catalyst carrier – a raw material for activated alumina, and can also be used as a molding binder for molecular sieves and silicate refractory fiber products, such as a binder for semi-synthetic rare earth Y-type molecular sieve cracking catalyst, as alcohol Dehydration to ethylene catalyst and ethylene oxide catalyst

SB Powder

Highly viscous alkoxide method pseudo-boehmite SB powder

The company’s high-viscosity alkoxide method boehmite products have a variety of pore sizes ranging from 0.35-0.55/0.6-0.8/0.8-1.3 specifications. The gelation property reaches the effect of imported SB powder (produced by Sasol, Germany). It is prepared by alkoxide method, high purity, no impurities, good pores, fast gel formation and transparent color, which can be used for catalysts and carriers in various occasions.
