چکیده انگلیسی
The objective of this research is to study the adsorption of biomethane gas by several different absorbents. The ultimate goal was to create a cost effective and safe fuel tank for use in domestic cooking applications in rural Thailand. Biomethane is a cleaned and upgraded fuel derived from biogas. It contains a minimum of 80% methane (v/v) with the remainder composed mostly of carbon dioxide. Specifically, the effects of pressure and temperature on the biomethane adsorption capacity of five different absorbents in a 28â¯l tank were studied. The pressure ranged between 3 and 9â¯MPa while the temperature range was 15-25â¯Â°C. The results showed that the adsorbent, Activated Carbon 3, had the highest biomethane adsorption capability. At higher pressures, greater biomethane adsorption was observed with the highest adsorption value of 164.3â¯Â±â¯0.5â¯g/l obtained at 9â¯MPa. Temperature had a smaller effect with higher temperatures producing less adsorption. At 9â¯MPa, as the temperature increased from 15 to 25â¯Â°C, the adsorbed biomethane decreased by 8%. The degradation in performance of the adsorbent was investigated and found to be negligible over 500 filling/emptying cycles. The selective adsorption of methane over the other biomethane constituents was investigated and also found to be negligible over 500â¯cycles. The Langmuir adsorption model was applied to estimate the maximum absorption capacity of each absorbent.
