Pseudo Boehmite Porous Aluminium Hydroxide Powder Cas 21645-51-2

Pseudo Boehmite (CAS 21645-51-2), also known as Alumina Monohydrate, is a white, porous powder with high purity, high pore volume, and high specific surface area. It is a precursor to activated alumina and is characterized by its excellent peptizing performance—it easily transforms into a stable colloidal state under acidic conditions. This makes it an indispensable material in the production of catalysts, adsorbents, and specialized ceramic binders.

Applications

Catalyst Carrier

The primary support material for hydrocracking, hydrogenation, and tail gas purification catalysts in the oil and gas industry.

Molecular Sieve Binder

Used as a high-strength binder for semi-synthetic Y-type molecular sieve cracking catalysts.

Adsorbents & Desiccants

Precursor for high-surface-area activated alumina used in gas drying and fluoride removal from water.

Specialty Ceramics

Applied in the production of high-purity alumina ceramics, abrasives, and refractory materials.

Packaging & Logistics

• Standard Packaging: 25kg multi-wall paper bags with plastic inner liner; 500kg or 1000kg jumbo bags.

• Loading Quantity: 15-18 MT per 20' FCL (depending on density and palletization).

• Storage: Store in a dry, ventilated warehouse. Keep away from moisture and acidic vapors.

Synonyms

Alumina Monohydrate; PB; Aluminium Hydroxide Oxide; Pseudo-Boehmite Powder.

Matching Materials

• Nitric Acid ($HNO_{3}$): Used as a peptizing agent to create alumina sols.

• Zeolites: Blended with Pseudo Boehmite for FCC catalyst production.

• Active Metals (Ni, Mo, Co): Impregnated onto the alumina support for specific catalytic reactions.
