| Feature | 1.Molecular sieve adsorption is a physical process that instead of a chemical changes. The adsorption process is reversible, called resolution or regeneration. 2.The zeolite molecular sieve has strong polarity in the crystal cavity, which reflects the adsorption selectivity of zeolite molecular sieve. 3.The size of the zeolite molecular sieve can be changed by ion exchange, thereby changing its performance and achieving the purpose of shape selective adsorption and separation of mixtures. 4.The surface of most zeolite molecular sieves has a strong acid center, and at the same time, a strong Coulomb field in the pores has a polarizing effect. These characteristics make it an excellent catalyst. | |
| Application | 1.Drying and removing of CO2 from natural gas,LPG,air,inert and athmospheric gases,etc. 2.Removal of hydrocarbons,ammonia and methanol from gas streams(ammonia syn gas treating). 3.Special types are used in the air break units of buses,trcks and locomotives. 4.Packed in small bags,it maybe used simply as a packaging desiccant. | |
