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.
