“…Specifically for natural gas storage and delivery, the effect of C2 + s alkanes composition and their adsorption behavior in a cyclic charge/discharge process can be of utmost importance in the appropriate definition of economic and technical viability of a given project (Mota, 1999). Studies on activated carbons as possible natural gas storage medium have been widely reported for various types of carbon materials (Matranga et al, 1992;Chang and Talu, 1996;Mota et al, 1997;Inomata et al, 2002;Lozano-Castello et al, 2002;Biloe et al, 2002;Tanaka et al, 2002;Molina-Sabio et al, 2003;Perrin et al, 2004), usually focusing on methane as the main constituent of natural gas. In a recent study (Cavalcante et al, 2003) activated carbon obtained from coconut shell was evaluated in regards to methane adsorption at pressures up to 40 bar.…”

-This paper presents experimental results for adsorption equilibrium of methane, ethane, and butane on nanoporous activated carbon obtained from coconut shells. The adsorption data were obtained gravimetrically at temperatures between 260 and 300K and pressures up to 1 bar. The Toth isotherm was used to correlate the data, showing good agreement with measured values. Low-coverage equilibrium constants were estimated using virial plots. Heats of adsorption at different loadings were also estimated from the equilibrium data. Adsorption properties for this material are compared to the same properties for BPL activated carbon and BAX activated carbon.

“…The porous structures can be created in the activation process by removing the disordered carbons, and by exposing the crystallites to activating agents [3]. Numerous studies have been carried out with different precursor materials and activation techniques to obtain ACs with high adsorption capacities [3], [10].…”

Abstract-The novelty of the present work includes the preparation of the granular activated carbon (GAC) from the agricultural waste and its application in storage of methane gas. GAC, prepared from Aegle marmelos fruit shell by chemical activation (H3PO4) was characterized by N2 adsorption-desorption isotherms. The shape of isotherm and pore size distribution (PSD) of prepared AC at optimum conditions showed that the adsorbent is rich in micropores (< 20 oA) with high surface area (1657 m2/g). Methane storage capacity of the prepared GAC was tested at different temperatures (293 and 303 K) and pressures (up to 800 psia) and the effects of porosity and temperature on adsorption capacity were determined.

“…Among the available energy resources in South America, natural gas (NG) has notably increased its production and consumption during the last years [16][17][18] ; consequently, some deficiencies should be eliminated such as its NG storage both in fixed or mobile deposits, considering that Compressed Natural Gas (CNG) involves its storage at pressures over 180 bars. Our focus is in the security improvement for the gas handling, the efficiency in the storage capacity, and the diminution of costs.…”

Natural gas storage in microporous carbon obtained from waste of the olive oil production

et al. 2008

A series of activated carbons (AC) were prepared from waste of the olive oil production in the Cuyo Region, Argentine by two standard methods: a) physical activation by steam and b) chemical activation with ZnCl 2 . The AC samples were characterized by nitrogen adsorption at 77 K and evaluated for natural gas storage purposes through the adsorption of methane at high pressures. The activated carbons showed micropore volumes up to 0.50 cm 3 .g -1 and total pore volumes as high as 0.9 cm 3 .g -1 . The BET surface areas reached, in some cases, more than 1000 m 2 .g -1.The methane adsorption -measured in the range of 1-35 bar-attained values up to 59 V CH4 /V AC and total uptakes of more than 120 cm 3 .g -1 (STP). These preliminary results suggest that Cuyo's olive oil waste is appropriate for obtaining activated carbons for the storage of natural gas.
