Numerical simulation of sorption/desorption processes in metal-hydride systems for hydrogen storage and purification. Part I: Development of a mathematical model

Integration of the Hydrogen-Storage Purification and Hydrogen Network

“…The hydrogen-storage reactor can be used to purify the hydrogen . It can separate a mixture with any hydrogen concentration and produce fresh hydrogen with a purity of 99.99999% .…”

Numerical study of hydrogen purification using metal hydride reactor with aluminium foam

“…In this work, a mathematical model, which was previously developed to analyse the processes in metal hydride systems for hydrogen storage and purification [10], was used. The model is similar to models used by other authors [see, e. g. 11,12], but unlike those models, it takes into account the presence of unabsorbed gas in the gaseous phase.…”

“…In [10] it was shown that the effective thermal conductivity of the metal hydride bed without aluminium foam can be calculated using Brugerman's equation: 3 .…”

“…For the definition of the permeability coefficient of the metal hydride bed without aluminium foam k , the Kozeny-Carman equation with the corrected constant A = 200 was used [10]:…”

Influence of the key parameters on the dynamic behavior of the hydrogen absorption by LaNi5

“…As a conclusion of their work, they proved that rapid load requires efficient cooling which is directly related to the feed rate. In another study carried by K. B. Minko et al [3], the authors perform the analysis of a model of a cylindrical metal hydride tank. They conclude that the concentration gradient in the bed is the main driving force of the flow of hydrogen.…”
