Ultraporous pseudo-transition alumina is a high-performance catalytic and adsorbent material designed with exceptional porosity and surface area, ensuring enhanced efficiency for industrial applications. Engineered with optimized alumina formulations, it improves adsorption capacity, promotes stable catalytic activity, and delivers superior thermal resistance for various chemical processes. This material is widely used in catalyst supports, adsorbents for gas purification, and advanced petrochemical refining applications, offering reliable performance for continuous industrial processing.
Product Overview
Ultraporous pseudo-transition alumina is an important catalyst support material in petrochemical industries. As petroleum resources become increasingly poor and heavy, there is a growing demand for large pores in catalyst supports. This product is synthesized through a low-cost hydrothermal method using amorphous alumina, overcoming the technical limitations of conventional methods that couldn’t achieve both high specific surface area and large pore diameter. The technology has reached internationally advanced levels.
Key Features
- High Specific Surface Area and Large Pore Diameter:Specific surface area up to 320 m²/g, pore volume reaching 1.5 ml/g, and average pore diameter over 20 nm.
- Concentrated Pore Size Distribution:Pore size is stable and uniform, with a high retention rate of pore structure during the forming process.
- Sulfur and Sodium-Free:No sulfur, sodium, or other impurities introduced during production, ensuring high product purity.
- Customizable Pore Structure:The pore structure can be adjusted over a wide range and customized to meet user-specific needs.
Applications
- Petrochemical Industry:Widely used as a catalyst support in hydrotreating agents, refining agents, and other catalysts, meeting the demand for large-pore alumina supports.
- Catalyst Supports:Replaces conventional pseudo-transition alumina products made by neutralization, offering higher efficiency and more stable catalytic performance.
- Petroleum Refining:Suitable for environments where petroleum resources are degrading and becoming heavier, supporting more efficient catalytic reactions.
