Abstract

Abstract : Magnesium is considered as a potential material for the separation of hydrogen from different gas streams (CH4 /H2, syngas, natural gas, etc.). Herein, an elemental mixture of Mg and Ni (5 wt%) is used for selective absorption of hydrogen from a CH4 /H2 (90:10) mixture at 350 °C. The performed studies (X‐ray diffraction, thermogravimetric analysis, differential scanning calorimetry, and gas chromatography) show that analyzed material absorbs 4.5 wt% of hydrogen from CH4 /H2 gas mixture and can be successfully applied for H2 separation. The proposed material may also be a promising system to capture hydrogen transported through natural gas networks. Abstract : This study shows that Mg‐based material can absorb up to 4.5 wt% of H2 (at 350 °C) from CH4 /H2 gas mixture. Moreover, the activated material is able to separate all of the hydrogen from gas mixture from limited volumes.
