Enhancement effect of micropore filling for supercritical methane by magnesia dispersion

A comparative study of various microporous materials to store hydrogen by physical adsorption

“…It can also be observed that H 2 adsorption in SWCNT reaches its saturation value below 1 bar. The data were fitted to the modified DR equation for micropore filling of supercritical gases [32,33], in order to derive a parameter (q st q¼1=e ) that characterizes the H 2 Table 3 e Textural properties of the carbon materials calculated from N 2 adsorption at 77 K. interaction with the materials. The results are presented in Table 4 and are in agreement with the observations described above.…”

Micropore Filling of Supercritical Xe in Micropores of Activated Carbon Fibers

“…The micropore filling of N 2 and Ar vapor in micropores of ACF has been studied (14,15). Also the micropore filling of supercritical N 2 and CH 4 was studied by use of the high pressure measurement (16,17). However, no study on adsorption of supercritical Xe in carbon micropores has been reported as far as we know.…”

Changes in microporosity and CH4 adsorptivity of preoxidized pitch-based activated carbon fibers by Mg deposition

“…Metal oxide/hydroxidedeposited ACFs can be catalysts improving performance in reactions such as selective catalytic reduction of NO x using NH 3 [14], reduction of dissolved oxygen in water with hydrazine [15], and photocatalytic reaction [16]. They are also efficient adsorbents for supercritical gases such as NO [17][18][19] and CH 4 [20,21]. Kaneko et al have found that surface modification of ACFs by various kinds of metal oxides/hydroxides leads to an evident enhancement of CH 4 adsorptivity [20].…”

Kaneko et al have found that surface modification of ACFs by various kinds of metal oxides/hydroxides leads to an evident enhancement of CH 4 adsorptivity [20]. Hattori et al reported that highly dispersed nickel oxides that remarkably enhance CH 4 adsorption form a special local structure on the carbon surface with respect to bulk powders [21].…”
