陶瓷球

Our DTC series are generally used for catalyst bed support for oil refining, petrochemical and natural gas applications. The product is often used in the temperature range of 100°C to 500°C. Most of desulphurization systems in oil refineries use this kind ceramic ball. It is a standard item for the desulphurization process. Products of these specifications are produced from high quality chemical–porcelain clay, which has excellent stability, high crushing strength and resistance to thermal shock.In addition to our DTC Inert Balls, we also produce other shapes such as full cylinders, hollow cylinders and prisms as supporting and covering layers for contact masses in reactors according to customers’ specific requirements for different application.
