-
Porous ceramic balls are a type of spherical filler material made from high-quality chemical ceramic raw materials (such as alumina, kaolin, etc.) and obtained through high-temperature firing. They have a large number of open pores and a high specific surface area. Unlike solid ceramic balls, their interiors and surfaces are filled with interconnected micro-pore channels, which endows them with unique properties.
Characteristic:
1. High specific surface area: The dense internal microporous structure makes its specific surface area much larger than that of solid ceramic balls, providing sufficient contact space for reactants.
2. Excellent adsorption performance: It can adsorb moisture, impurities and harmful substances in gases or liquids.
3. Good mechanical strength: It has high compressive strength and wear resistance, capable of withstanding bed pressure and the impact of materials, and has a long service life.
4. Stable chemical inertness: It is resistant to acids, alkalis and corrosion, and can remain stable in various harsh chemical environments, not participating in reactions.
5. High temperature resistance: It can withstand temperatures above 1000℃, suitable for high-temperature reaction environments.
6. Low resistance and large porosity: The bed structure is loose, effectively reducing system resistance drop.
7. Uniform appearance: The spherical structure ensures uniform distribution during filling, avoiding the occurrence of channel flow.
Application：
1. Petrochemicals (Core Application)
◦ Function: As a covering and supporting material for the catalyst bed, it filters impurities, protects the catalyst, and evenly distributes the airflow.
◦ Application: Widely used in hydrogenation, reforming, cracking and other reactors.
2. Environmental Protection and Gas Treatment
◦ Function: As an adsorbent or catalyst carrier, it is used for purifying exhaust gas and drying air.
◦ Application: Applied in exhaust gas desulfurization and denitrification, compressed air drying,变压吸附 oxygen and nitrogen production， etc.
3. Chemical Industry
◦ Function： As a catalyst carrier or reaction filler.
◦ Application： Used in various organic synthesis， gas purification and separation in chemical processes.
4. Metallurgical Industry
◦ Function： As a purification filler.
◦ Application： Used in the purification and recovery systems of blast furnace gas and coke oven gas.
