Hydrocarbons Gas Storage on Activated Carbons

Sonia Ben Yahia and Abdelmottaleb Ouederni

Abstract—The present study provides an experimental investigation of charge-discharge cycles of hydrocarbon gas mixture (butane and propane) in a volumetric apparatus set up filled with various activated carbons under low pressure of about 0,4MPa at 303K. This comparative study was carried out using one commercial activated carbon from NORIT company and two olive stones based activated carbons produced by chemical activation process using orthophosphoric acid with carbonization in nitrogen steam giving CAGOC and with carbonization in steam nitrogen flow giving CAGOCom. The highest storage measured capacities was about 62 V/V for the chemical activated AC, 65 V/V for the steam-nitrogen activated one and 67 V/V for Commercial AC. In spite of an efficiency fall down from the second cycle, a total desorption yield was obtained for CAGOCom with weak modifications on porous texture during cyclic operation. All these results encourage grain based activated carbons use as good candidate for gas storage to vehicular applications.

Index Terms—Activated carbon, adsorption, desorption, olive stones, cyclic operation.
