Activated alumina is a versatile material widely used in adsorption, catalysis, and water treatment. Suppliers of activated alumina play a critical role in providing tailored products to meet diverse industrial needs. This article highlights key suppliers and their product offerings, focusing on material specifications, applications, and technical support.

Key Suppliers and Product Highlights

ChemicalBook

• Core Products: ChemicalBook lists suppliers for various activated alumina types, including Rhodium on activated alumina (5% Rh basis) and general-purpose activated alumina (3-5mm particle size).
• Specialization: The platform connects buyers with manufacturers offering catalyst carriers, adsorbents, and custom formulations, such as acidic activated alumina and catalyst carriers. 

• Technical Data: Provides detailed specifications like molecular formula (Al₂O₃), pH classification (acidic, neutral, alkaline), and activation methods.

Utopbio Co., Ltd.

• Product Focus: Alkaline activated alumina (pH 9) in 500g and 15kg packaging, designed for column chromatography and adsorption applications.
• Unique Features: Manufactured via dehydration of hydrate gels at 300–500°C, with adjustable activity (Brockmann scale I–V) based on moisture content.
• Applications: Used as a desiccant, catalyst, and adsorbent in organic synthesis and natural product purification.

Taodocs-referenced Suppliers

• Industrial-Grade Offerings: Suppliers highlighted in Taodocs provide activated alumina for defluoridation in drinking water, transformer oil regeneration, and gas drying (dew point as low as -70°C) .

• Regeneration Support: Expertise in optimizing regeneration conditions (e.g., sodium metaaluminate concentration) to maintain defluoridation efficiency.

Selection Criteria for Suppliers

1. Purity and Activity: Prioritize suppliers with strict quality control (e.g., 5% Rh loading for catalyst carriers) and activity certification .
2. Customization: Choose suppliers offering pH-specific grades (acidic pH 4, neutral pH 7.5, alkaline pH 9) and particle size options (3–5mm).
3. Technical Support: Opt for suppliers providing MSDS, regeneration protocols, and application guidance (e.g., defluoridation parameters).

Global Market Considerations

• Regional Availability: Asian suppliers dominate high-purity catalyst carriers, while European suppliers focus on chromatography-grade materials.
• Cost Factors: Bulk pricing for industrial desiccants (e.g., 15kg drums) vs. premium pricing for ultra-high purity catalyst supports. 

By evaluating these activated alumina suppliers and criteria, industries can source activated alumina tailored to their specific processes, ensuring efficiency and compliance with technical requirements.
