Original abstract
Currently when fossil fuel resources are decreasing and environmental protection is increasing, renewable energy sources are exploited more. Biogas (typically a raw mixture composed of methane, carbon dioxide and other minor components) can be one of the options how to replace some fossil fuel consumption. Specifically, upgraded biogas has the same utilization and advantages as natural gas. Upgrading biogas to biomethane is commonly utilized. In this process the most crucial operation is the separation of carbon dioxide (CO2) from biogas, which is carried out by technology based on unit operations like adsorption, absorption or membrane separation. The pressure swing adsorption (PSA) is the most widely used method for the separation of gases. It is a periodic batch process where adsorption is performed at a relatively higher pressure than atmospheric pressure and desorption (regeneration) at lower pressure than atmospheric pressure.

V současné době klesá využívání fosilních paliv, roste ochrana životního prostředí a obnovitelné zdroje energie začínájí být více využívány. Bioplyn může být jednou z možností nahrazení fosilních paliv. Přesněji, vyčištěný bioplkyn má stejná vlastnosti jako zemní plyn. Nejdůležitější operací při čištění bioplynu je odstranění CO2. Nejpoužívanější metodou je adsorpce za měnícího se tlaku, tzv. PSA. V článku se zabýváme optimalizací této metody pomocí průrazových křivek, jež byly měřeny na laboratoním zařízení.
