“…Moisture, especially at relative humidities (RH) exceeding 40%, can significantly reduce the capacity of adsorbents, such as activated carbon [56][57][58][59][60]. Some other adsorbents, for example silica gel and zeolites, are extremely sensitive to moisture and may require the gas to be almost dry (RH<10%) [20,61].…”

“…The affinity coefficient (β) and the pore volume adjusting coefficient (k v ) are parameters that need to be estimated [64,65,67,69] or fitted to adsorption isotherm data. For the most part, we could find literature data for many of the species shown in Appendix 2 and fit equation (5) to those data [50,59,60,67,[69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84]. For the cases where data were not available (8 species), the parameters were correlated by using a reference species of similar properties and the method developed by Ye et al [67].…”

“…Activated carbon is widely used in adsorption separation processes as a result of its attractive adsorption properties (Rudisill et al 1992;Eissmann and LeVan 1993;Russell and LeVan 1997;Taqvi et al 1999). Correspondingly large amounts of data have been published on the adsorption isotherms of pure and multi-component gases in activated carbon.…”

“…However, natural gas requires special storage systems (Rudisill et al 1992) because of its low volumetric energy density (Menon and Komameni 1998;Castello et al 2002;MacDonald and Quinn 1998;Lee et al 2006Lee et al , 2007Balathanigaimani et al 2006). As far as storage is concerned, the adsorbed natural gas (ANG) storage system provides a feasible process capable of solving several problems in natural gas storage (Lee et al 2007;Balathanigaimani et al 2008a,b;Moreno and Giraldo 2005a,b;Huertemendia et al 2005;Steckler et al 1986;Gunn 1965;Russell et al 2006;Lerchner et al 2002). ANG is a method where both adsorption and compression are carried out simultaneously to allow the storage of natural gas at convenient temperatures and pressures compared to conventional methods (Lee et al 2007;Balathanigaimani et al 2008aBalathanigaimani et al ,b, 2009aGunn 1965;Russell et al 2006;Lerchner et al 2002Lerchner et al , 2006Garrone et al 1981;Giraldo et al 2003;Ioannidou and Zabanitou 2007).…”

ABSTRACT:Methane adsorption onto different types of carbon monoliths was studied at two temperatures (298.15 K and 303.15 K) and at pressures up to 35 atm in a volumetric adsorption apparatus. The mass basis results for methane adsorption indicated that the methane adsorption capacities of the carbon monoliths increased with increasing surface area, total pore volume and micropore volume. The maximum volumetric methane uptake of the carbon monoliths synthesized was 165 v/v at 298.15 K and 35 atm employing steamactivated monoliths derived from petroleum coal tar. The Clapeyron-Clausius equation was used to describe the interaction between the guest molecules and the adsorbent at low surface coverage and the energetic heterogeneous surface nature of the adsorbent, respectively. The methane storage capacity was found to be a function of the micropore volume and the developed superficial area.

Experiments of the adsorption cycles, which include adsorption, steam desorption, and drying/cooling, are conducted using a well instrumented pilot-scale apparatus with toluene as the sorptive. Special attention can be paid to the temperature profiles and the changes in water and toluene loading during drying since there is the possibility to take samples from inside the column. Water isotherms were gravimetrically determined and correlated with the association theory of Talu and Meunier. The mathematical description of the air drying of the packed bed with activated carbon is based on an equation system with coupled heat and mass transfer between the bed and the fluid. The first calculations show good agreement with experimental results.
