▎ 摘　　要

NOVELTY - Hydrogen purification comprises providing hydrogen comprising a multi-stage hybrid membrane, each membrane comprising a screen, a first layer (20) formed on the screen, and a second layer (30) formed on the first layer. A gas stream is pumped through the hydrogen concentrator. The gas stream comprises syngas including hydrogen and additional gas. Hydrogen is separated from the mixture containing hydrogen and additional gas. The gas stream pumping comprises keeping the hydrogen moving within the hydrogen concentrator and pulsing in the additional gas. USE - Method for hydrogen purification. ADVANTAGE - The membrane system incorporates minimal capital expense, low carbon footprint, and operational flexibility while meeting the volume throughput of current and future commercial applications. The layer has a more open structure than layer and allows for a prefiltering and faster throughput of material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view illustrating the construction of membrane systems. 5Membrane system 10Gasses 20, 30Layers
