Desorption was carried out in a stream of pure nitrogen to simulate pressure swing by lowering the partial pressure of CO. Regeneration was performed at a range of N flow rates (50-100 ml.min) and over a temperature range of 75-140°C. Increasing the temperature from 120°C to 140°C resulted in an increased amount of CO being desorbed. Delaney and others (2006a,b) have investigated mesoporous carbon based adsorbents functionalised with amines. Prepared in monolithic form, their electrically regenerable properties may make them suitable for CO capture by electrical swing adsorption (ESA). Rapid and uniform desorption of CO can be achieved by passing an electrical current through the carbon adsorbent. The conceptual design is shown in Figure 8.
