Description:
The alumina ball’s mainly function is a kind of catalyst bed support media. It is widely utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection etc.

As a kind of tower packing material, the inert alumina ceramic ball has the characteristics of high temperature resistance, pressure resistance, low bibulous rate, stable chemical properties. This kind of the catalyst bed support media can endure the corrosion of acid, alkali and other organic solvent. The inert porcelain ball can withstand temperature changes during the production process.

The main functions of inert alumina ceramic ball: 1. to increase gas or liquid distribution point, 2. to support & protect less-strength active catalyst.
