Hydrogen Purification
Pressure Swing Adsorption (PSA) has proved to be an effective and economic way for hydrogen recovery. Nowadays, our capacity of PSA system is with multi-bed ranges from a few hundred Nm3/h to large scale plants with more than 400,000 Nm3/h. The hydrogen purity can reach up to 99.9999%.
Binderless 5A and activated carbon are key adsorbents to remove feed gas impurities such as CO, N2 and CH4. There are four main groups of users for a hydrogen purification system:
1. Steam Reforming (Hydrogen Plants)
2. Catalytic Reforming Net Gas
3. Hydrocracker and Hydrotreater Purge Gases
4. Hydrocracker Flash Gas
Hydrogen Getter
Scheme of the Hydrogen Adsorption Mechanism of Product Code: JLHA-100
Step 1：H2 diffuses into the channel of zeolite and contact with Ag ion (physical adsorption)
Step 2：H2 is catalyzed by Ag ion to form H2O. H2O is further adsorbed by zeolite(chemical adsorption)
Location of Ag in the zeolite
Macroscopically, Ag ions are located in the cages of FAU
Microscopically, Ag ions bond with framework oxygen to form ionic bonds
Ag ion reacts with H2 to produce Ag0 and H+. H+ bonds with framework O to form hydroxyl
Ag ion is reduced by H2 to form Ag0
Ag0 aggregates with Ag ion to form positively charged clusters
Ag clusters further react and consume more H2
The more dispersed Ag exists in the form of Ag+, the more H2 is exposed to it, with higher utilization efficiency of Ag and better hydrogen adsorption performance.
Do you have 13X nano molecular sieve Zn Zeolite powder? Yes, we are a leading factory.
