(1). Product features
AA open-hole ceramic ball is a new product developed by our company on the basis of inert alumina ceramic ball. Increase the specific surface area and porosity, thereby increasing the dispersion and flux, and reducing the resistance of the system. It can be widely used in petroleum, chemical and natural gas industries to replace inert alumina ceramic balls as catalysts and covering supporting fillers.
The product won the national patent in 1995, the first prize of provincial outstanding new product in 1996, and the provincial patent product excellence award in 1997. Since the product was put on the market, it has been favored and praised by users. It has been proved by users that in the same reactor and reactor under the same operating conditions, compared with the original covering support material, the vapor-liquid distribution is more uniform, the flow rate is significantly increased, the system resistance is significantly reduced, and the catalyst does not agglomerate , Does not burn, thus prolonging the service life of the catalyst.
