“…The isosteric heat of adsorption is a valuable thermodynamic property which provides useful information regarding the interaction between the adsorbent and adsorbate, as well as of the energetic heterogeneity of the adsorbent surface (Taqvi et al 1999;Salame and Bandosz 1999;Menon and Komarneni 1998;Balathanigaimani et al 2008aBalathanigaimani et al ,b, 2009a. On the basis of the Clapeyron-Clausius equation, the isosteric heat of adsorption has been determined by Balathanigaimani et al (2009a,b) as:…”

“…Such monolithic forms offer an increase in density by reducing the excess void volume (Paruchner and Rodrigues Reinoso 2007), compactness and easy handling. Usually, carbon monoliths have been made by compressing activated carbon on its own (Balathanigaimani et al 2006) or as a mixture with a binder (Russell and LeVan 1997;Balathanigaimani et al 2009a,b;Paruchner and Rodrigues Reinoso 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.

“…Natural gas is considered to be one of the most promising alternative fuels, because of its abundance, low cost and minimal emissions. However, natural gas requires a special storage system [1], because of its low volumetric energy density [12,13,[20][21][22][23][24], and the adsorbed natural gas (ANG) storage represents a feasible solution to this technological challenge [22][23][24][25][26][27][28][29][30]. ANG methanol is a method where both the adsorption and compression processes are carried out simultaneously, in order to store natural gas under convenient temperatures and pressures compared to conventional methods [10,23,[28][29][30][31][32][33][34][35][36][37][38][39].…”

Methane adsorption by different forms of activated carbon obtained from coffee husks, including monolith honeycomb and disc types, was studied by activation with zinc salts and potassium hydroxide at 298.15 K and 303.15 K and pressures up to 30.00 atm in a volumetric adsorption apparatus. We observed increased methane adsorption capacity on a mass basis in the different activated carbon monoliths with increasing surface area, total pore volume and micropore volume, with the honeycomb type displaying the highest methane absorption capacity. The maximum volumetric methane uptake by the synthesised carbon monoliths was observed to be 130 V/V at 298.15 K and 30.00 atm for honeycomb monoliths synthesised with zinc chloride (ZnCl<sub>2</sub>) and Polyvinyl alcohol (PVA) as the binder. Adsorption calorimetry results were used to describe the interaction between guest molecules and the adsorbent at low surface coverage and the energetic heterogeneous surface nature of the adsorbent

Influence of compressing pressure on macro void formation of carbon monolith for methane adsorption

INTRODUCTIONThe ANG has been known as a modern technology in which natural gas is adsorbed by porous materials at relatively low pressures around 3.5 MPa and at room temperature. Once a good medium with sufficient working capacity is developed, ANG will be competitive technically and economically comparing with the conventional storage methods such as LNG and CNG. In order to make this ANG as a competitive commercial technology, the DOE had set a storage target of 180 V/V at 3.5 MPa and 298 K in 2000 and modified this target up to more than 220 V/V that is the maximum achievable capacity based on carbon-based materials [1,2]. Volumetric storage capacities for methane (a major constituent of natural gas) have been reported in the range from 150 to 200 V/V from bench-scale experiments but there is no information regarding the practical application of ANG technology. Methane adsorption on carbon materials has a rich history. ACs are excellent adsorbent materials for methane storage and expected to possess high surface area and proper pore size distribution. The ACs have been produced from various Narandalai et al. Mong. J. Chem., 18 (44), 2017, 24-35 https://doi.org/10.5564/mjc.v18i44.934 Influence of compressing pressure on macro void formation of carbon monolith for methane adsorption ABSTRACTCarbon monoliths for adsorbed natural gas (ANG) storage were prepared from Mongolian anthracite-based activated carbons using carboxy-methyl cellulose as a binder under different compressing pressures. Nitrogen adsorption/desorption experiments were carried out to obtain the specific surface area, pore volume, and pore size distribution of the monoliths.Methane adsorption experiments on the carbon monoliths were conducted at different temperatures and pressures up to around 3.5 MPa in a high pressure volumetric adsorption apparatus. As expected, adsorption results indicated that the methane adsorption capacity of the carbon monoliths increased with increasing specific surface area and packing density.The maximum volumetric adsorption of methane was observed as 163 V/V at 293 K and 3.5 MPa on a carbon monolith sample, PMAC1/2-3-65, that does not have the highest specific surface area but relatively high packing density comparing with other monoliths, which implies that two physical properties contribute contradictorily to the methane adsorption capacity. Based on experimental results, the carbon monoliths prepared from Mongolian anthracite-based activated carbons can be promising media for ANG storage application.
