Microporous ceramic balls, also known as porous ceramic balls, are created by perforating inert alumina ceramic balls. Therefore, they have the same bulk void fraction as inert ceramic balls, serving to cover and support catalysts while dispersing gas and liquid. Additionally, they have 20-30% additional structure pores with adsorption capabilities, enabling them to adsorb impurities in filtered oil products. This helps protect the catalyst and extend the operating cycle of the equipment.
