Hydrogen and Deuterium Solubility in Commercial Pd–Ag Alloys for Hydrogen Purification

ChemEngineering, 2017
Pd–Ag alloys with compositions close to 23–25% Ag are considered as a benchmark for hydrogen permeability. They are used in small scale reactors for hydrogen separation and purification. Permeability and solubility are strictly mathematically correlated,

Hydrogen Purification Performance Optimization of Vacuum Pressure Swing Adsorption on Different Activated Carbons

Energies, 2021
Hydrogen purification is an important part of hydrogen energy utilization. This study aimed to perform hydrogen purification of multi-component gas (H2/CO2/CH4/CO/N2 = 0.79/0.17/0.021/0.012/0.007) by one-column vacuum pressure swing adsorption (VPSA) and

Predicting Target Values of Hydrogen Networks with Purification Unit

Chemical Engineering Transactions, 2017
Hydrogen utility consumption can be reduced further when purification unit is introduced in a hydrogen network. However, targeting and design of the networks involving purification is more difficult than that of the ones involving reuse only.
