Yesterday, we received a rigorous inquiry from Mr. Li, a Korean petrochemical engineer: "We want to load alumina ceramic balls into the hydrotreating reactor as a catalyst bed protector. We currently need to purchase Φ6mm ceramic balls. The impurity content of the feed oil is relatively high, and the reactor operating pressure is 8.0MPa and the temperature is 380°C. Under high-pressure and high-temperature operation, are there any special requirements for the crushing strength of the ceramic balls? Do you have suitable ceramic balls?" After understanding the customer's needs, we immediately answered the customer's questions and provided selection guidance to help the customer choose the right ceramic balls.
Zibo Xiangrun gave the customer a clear response: "Yes, we have industrial alumina ceramic balls that far exceed standard requirements. Ceramic balls used under normal operating conditions are not suitable for this high-pressure environment."
For this customer's high-pressure hydrogenation reactor, we recommended ceramic balls with an average crushing strength exceeding 130N/particle, or even 150N/particle. Furthermore, the wear rate must be below 0.5%. This ensures the ceramic balls are resistant to wear and dust generation under long-term operation and airflow.
After clearly defining the technical requirements, we recommended Zibo Xiangrun's high-performance alumina ceramic ball series to our Korean customer.
Product Model: [92% Alumina Ceramic Ball]
Key Data:
Specifications: Φ6mm, customizable size (spherical, uniform).
Crushing Strength: ≥ 150 N/particle (actual data typically stabilizes at 160-180 N/particle).
Abrasion Rate: ≤ 0.1% (far below the 0.5% requirement).
Al₂O₃ Content: ≥ 92% (ensuring excellent chemical inertness and thermal stability).
This product is designed specifically for high-pressure, high-temperature reactors such as hydrocracking and hydrorefining. Its strength fully meets and exceeds the customer's demanding 8.0 MPa operating conditions.
In the design of the bed protection system, even the slightest error can lead to a huge mistake. A minor mistake can result in significant financial losses. If you have any questions or needs regarding alumina ceramic balls, please contact Zibo Xiangrun Environmental Engineering Co., Ltd., a professional alumina manufacturer.
