China 17%AL2O3 Inert Alumina Ceramic Ball Manufacturer, Factories
17%AL2O3 Inert Alumina Ceramic Ball (Catalyst Support Media) are the most widely used as Catalyst Support Media in the world wide because of their excellent consistence and reliability. It produced by very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.
It's widely used in petroleum, chemical, fertilizer, gas and environmental protection industries, as a catalyst in the reactor to cover support material and tower packing. It has a high temperature and high pressure resistance, bibulous rate is low, the characteristics of the chemical performance is stable. Can withstand the erosion of acid, alkali and other organic solvents, and can endure in the production process of temperature changes. Its main function is to increase gas or liquid distribution points, support and protection intensity is not high activity of the catalyst.
