Product introduction
5A molecular sieve is a chemical substance with the molecular formula of 3/4CaO-1/4Na2O-Al2O3-2SiO2-9/2H2O.
Silicon to aluminum ratio:SiO2/AI2O3≈2,
effective pore size:about 5Å
Product characteristics
5A molecular sieve has a well-developed three-dimensional pore structure, and the pore diameter of the crystal is 0.5nm mainly used in (PSA) variable pressure adsorption H₂, CO and O₂ production devices and large-scale n-isomeric alkane separation devices in petrochemical enterprises and other industrial fields.
1、Higher adsorption capacity, larger specific surface area and pore capacity, faster adsorption speed.
2、Stronger adsorption selectivity ensures greater separation coefficient between components and more complete desorption at room temperature.
3、Smooth and hard surface, high strength and low abrasion rate ensure no powder fall under high strength airflow.

Typical applications
1.Conversion gas or hydrogen reforming
2.Methanol cracking gas or methanol choke gas
3.Ammonia tail gas
4.Coke oven gas, barren gas, water gas
5.Refinery hydrogenation low fraction gas
6.Catalytic dry gas
The purity of hydrogen production is usually increased to 99.9+%, and the hydrogen recovery rate is 60% ~ 90%.
Feed hydrogen concentration > 55% is considered economical and reasonable
If the feed hydrogen content is between 40% and 50%, it can be economically upgraded according to the site specific requirements
If the feed hydrogen content is below 40%, it is difficult to achieve economic rationality
