Biyolojik olarak üretilen gaz karıșımı direkt kullanım için uygun değildir. Çünkü hidrojenin derișimi yakıt hücrelerindeki uygulamalar için yeterli derecede yüksek değildir. Biyogaz karıșımı H2 yanında N2 (bașlangıç așamasında anaerobik șartları sağlar) ve CO de içerir. Bu yüzden gaz karıșımından hidrojen geri kazanılmalı ve deriștirilmelidir. Kimyasal absorpsiyon prosesi, basınç salınımlı adsorpsiyon prosesi, membram sistemler ve membran kontaktör sistemi gerikazanım ve deriștirme ișlemlerinde kullanılabilir. Bu makalede genel olarak gaz arıtım sistemleri verildi

Purification Of Hydrogen From Gaseous Mixture Produced From Biohydrogen Production System

Öz

Gaseous mixture produced by a biologically is not suitable for direct utilization. Because the concentration of hydrogen is not high enough for application in fuel cells. Biogas mixture contains N2 (to ensure anaerobic conditions initially) and CO2 beside H2. Therefore hdrogen from the gaseous mixture must be recovered and concentrated. Chemical absorption processes, pressure swing adsorption processes, membrane systems and membrane contactor system can be used in the recover and concentrate. In the paper an overview of common gas purification systems is given
