Siangsai A., Kumpoomee N., Rangsunvigit P., Kitiyanan B., Kulprathipanja S., 2014, Comparative Study of Methane Adsorption on Activated Carbon and Metal Organic Frameworks, Chemical Engineering Transactions, 39, 523-528.
This study compared the methane adsorption on activated carbon with and without the treatment with sulphuric acid (H2SO4) and potassium hydroxide (KOH) and metal organic frameworks (MOFs)–Basolite C300 and Basolite Z1200. In the experiment, methane gas was pressurized up to 500 psia and the temperature was set at 303 K. The results showed that, gravimetrically, Basolite C300 had the highest methane adsorption capacity of 8.95 mmol/g. The chemical treatments of activated carbon, both H2SO4 and KOH, resulted in the increase in the surface area and pore structure of the activated carbon. Moreover, based on a 70 L storage tank, the addition of H2SO4 treated-activated carbon increased the amount of methane gas in the tank up to 51.7%.
