Perforated ceramic ball
Perforated ceramic ball is developed on the basis of inert ceramic ball. It has an adequate mechanical strength, good chemical and thermal stability as the normal inert ceramic  ball. Furthermore, it has larger surface area and void space which directly make the dispersion  and flux of the fluids increased, and bring down the resistance of the system resulting from the perforated holes on the ball. As a new efficient catalyst support and covering material, it has been widely used in oil refinery, chemical, fertilizer production, natural gas and environmental protection.
