5A Molecular Sieves

Descripción del producto

5A molecular sieve, also called Calcium A molecular sieve, non-toxic, odorless, nonflammable, non-explosive, insoluble in water and organic solvents, but soluble in strong acid and strong base. Its pore diameter is 5×****0m, can adsorb any molecules which pore diameter is smaller than 5×****0m. In addition to the effect of 3A, 4A molecular sieves, it also can adsorb C*-C4 n-alkanes, ethylene chloride, bromoethane, butanol, etc. 5A molecular sieve can be applied to pressure swing adsorption separation, heterogeneous hydrocarbon separation and coadsorption of water and carbon dioxide. Yuanying 5A molecular sieve has ion exchange capacity and catalytic activity, also has a great affinity to water, under high temperature still has good adsorption ability, it has good catalysis to some organic gas phase reaction.
Application
1. The depth desiccation and purification of gases and liquids, purification of nitrogen, hydrogen, cleaning hydrogen sintering furnace
2. Through a selective adsorption process, isolated n-alkane frombranched-chain hydrocarbon and cyclic hydrocarbon, currently in industry used for large-scale pressure alkane separation process
3. Desiccation, desulfurization, removal of carbon dioxide for petroleum, petroleum gas and natural gas
4. Nitrogen oxygen separation, nitrogen hydrogen separation, making oxygen, nitrogen and hydrogen
5. Petroleum dewaxing, can be used as a adsorbent in dewaxing technology based on vapour as desorbent.
5A molecular sieve regeneration
1. Moisture removal: According to pressure, temperature and water of regenerate gas. Normally **0～**0℃ dry gas under 0.3～0.5kg/cm through molecular sieve bed layer **4 hours, exit temperature **0～**0℃, then cooling.
2. Removing organic matter: Used vapour instead of organic matter, then repeat step 1.
