Three-Dimensional Pore Structure
5A molecular sieve has a developed three-dimensional pore structure, with a crystal pore diameter of 0.5nm, mainly used in pressure swing adsorption (PSA) H₂, CO, and O₂ production devices and large-scale normal and isoalkane separation devices in the petrochemical industry.
1 Higher adsorption capacity, larger specific surface area and pore volume, faster adsorption speed.
2 Stronger adsorption selectivity ensures a larger separation coefficient between components, and more complete desorption at room temperature.
3 Smooth, hard surface, high strength and low abrasion rate ensure no powder dropping under high-intensity airflow scouring.

Methanol cracking hydrogen production unit
Methanol cracking-pressure swing adsorption hydrogen production technology is a kind of methanol, water as raw materials, at a certain temperature and pressure by the catalyst into a mixed gas into a certain temperature and pressure by the catalyst cracking into a hydrogen-containing mixed gas, and then through the pressure swing adsorption purification of hydrogen technology.
Natural gas hydrogen production unit
The technology uses natural gas to undergo a chemical reaction with water vapor in a special reformer filled with a catalyst after pressurized desulfurization to generate a converted gas containing hydrogen, carbon dioxide and carbon monoxide. After part of the heat is recovered by the waste pot, CO in the converted gas is converted into H?, and the converted gas is purified by pressure swing adsorption (PSA) after cooling and condensing gas-liquid sharing.
Pressure swing adsorption hydrogen extraction device
After the mixed gas containing hydrogen (H₂) enters the adsorption tower of pressure swing adsorption (PSA) device, because the adsorption capacity of the adsorbent in the adsorption bed for each component in the gas mixture varies with the pressure change, the impurities in the feed gas are adsorbed during pressurization, and the components (hydrogen) that are not easily adsorbed are output as products from the outlet end of the adsorption bed. During decompression, the adsorbed impurities are desorbed and the adsorbent is regenerated at the same time, at least four adsorbent bed cycles are used to operate to achieve a continuous output of product hydrogen.
VPSA pressure swing adsorption oxygen plant
Multi-tower combined VPSA pressure swing adsorption oxygen production technology is a new process with low energy consumption, low noise and low maintenance cost. It has been accepted by the first set of devices in Zhejiang Province and is widely used in non-ferrous smelting, glass smelting, iron and steel smelting, chemical industry, paper making and other industries.
