Application:
It 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, further more, it has larger surface area and free void 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 support and covering material of catalyst, it has been widely used in oil refinery, chemical, fertilizer, natural gas and environment protection industries since put into market .
