High-Pressure Methane Adsorption on NaX and NaY Zeolites with Different Si/Al Ratios

High-Pressure Methane Adsorption on NaX and NaY Zeolites with Different Si/Al Ratios

One method of increasing the storage capacity of compressed natural gas, an alternative for vehicular fuel, is by adsorbing it on to microporous solids such as zeolites or activated carbons. NaX and NaY zeolites with different Si/Al ratios have been synthesized and characterized. Experimental adsorp...
