Claus Alumina Spherical Catalyst for Support Layer AOK-78-61

Intended to improve gas distribution in the reactors, is also used as a catalyst and support layer.
Applications:
•        Refining
•        Metal industry
•        Gas processing
•        Oil producing

FEATURES AND ADVANTAGES
• Is also used as a Claus catalyst so to increase the unit operational resource;
• Less bulk density compared to the porcelain spheres.
