Inert ceramic balls
Pack: polypropylene bags of 25 kg net
Inert ceramic balls are loaded to the industrial reactors:
- for the improvement of dynamical properties of the gases or liquid media;
- as the pressing material;
- as the protective layer for the catalyst.
The ceramic balls manufactured with material, providing the balls stability under hard-operation conditions, such as high pressure drops, high temperatures, strong acids or alkalies. The mail applications of the inert ceramic balls: sulphur removal form the gas streams, hydrocracking, hydrogenation, reforming. The sizes and physical properties depend on the operating conditions. The widely used grades of the ceramic balls and their parameters:
