Product Overview

This γ-phase aluminum oxide represents a premium-grade catalyst support material engineered for demanding laboratory applications. The material features a high surface area (typically 150-300 m²/g) combined with a unique bimodal pore structure that provides both mesopores and macropores. This dual porosity system enhances mass transfer while maintaining excellent mechanical stability. The alumina undergoes rigorous purification processes to ensure minimal impurities, with typical metal oxide content below 0.1%. Its thermal stability extends up to 1100°C, making it suitable for high-temperature applications. The powder exhibits consistent particle size distribution (typically 50-200 μm) and demonstrates excellent resistance to acidic/basic environments. The material’s high crush strength and low abrasion characteristics ensure long-term performance in fixed-bed reactors. Each batch undergoes strict quality control to verify surface area, pore volume, and phase purity, with certificates of analysis provided for traceability.

FAQs

1.

What is the typical surface area range for this γ-alumina?

The material typically exhibits a surface area between 150-300 m²/g depending on the specific production batch and thermal treatment history. 2.

How does the bimodal pore structure benefit catalyst applications?

The combination of mesopores and macropores facilitates efficient reactant diffusion to active sites while minimizing pressure drop in packed beds. 3.

What purification methods are used to achieve high purity?

The alumina undergoes multiple washing steps with high-purity acids followed by calcination at controlled temperatures to remove trace metal impurities. 4.

Can this material be used in fluidized bed applications?

While primarily designed for fixed-bed systems, the particle size distribution can be adjusted for fluidized bed use with proper attrition resistance testing. 5.

What documentation is provided with each batch?

Standard documentation includes certificate of analysis with surface area data, pore volume measurements, phase composition, and trace metal analysis.
