Hydrogen-methane mixtures draw attention due to an idea of injection of hydrogen into natural gas network, thus lowering the need of huge investing in development of hydrogen infrastructure. Extraction of hydrogen from dilute mixtures with natural gas differs from traditional separations, since hydrogen concentration is low. Due to selective absorption of hydrogen from the feed, epy metal hydrides purification achieves high values of separation efficiency. We have experimentally demonstrated successful separation of the hydrogen (10%) – methane (90%) mixture at inlet pressure 9.5 bar by the LaNi 4.8 Mn 0.3 Fe 0.1 intermetallic compound in one step with roundtrip (absorption/desorption) hydrogen recovery 74% and absorption hydrogen recovery 76%.
