The activated alumina for PTA produced by Zibo Xiangrun is white spherical with high purity and strong adsorption capacity. It is widely used in PTA tail gas purification to remove impurities such as water, acetic acid, and tetrabromomethane.
The core role of activated alumina for PTA
In the PTA production process, activated alumina is mainly used as a catalyst carrier and impurity adsorbent, and is applied to the following key links:
Oxidation reaction section: carrying metal catalysts such as cobalt and manganese to promote the oxidation of paraxylene to terephthalic acid.
Hydrogenation refining section: adsorb impurities in the reaction liquid to improve the purity of PTA products.
Features and advantages

• Higher specific surface area
• Optimized pore volume design
Physical properties:
• Higher compressive strength
• Excellent wear resistance
• Good thermal stability
Chemical properties:
• Adjustable surface acidity
• Extremely low impurity content
• Excellent resistance to hot liquid aging
