The carbonized PAF-1 derivatives formed by high-temperature KOH activation showed a unique bimodal microporous structure located at 0.6 nm and 1.2 nm and high surface area. These robust micropores were confirmed by nitrogen sorption experiment and high-resolution transmission electron microscopy (TEM). Carbon dioxide, methane and hydrogen sorption experiments indicated that these novel porous c...
In most applications of nanoporous materials the pore structure is as important as the chemical composition as a determinant of performance. For example, one can alter performance in applications like carbon capture or methane storage by orders of magnitude by only modifying the pore structure. For these applications it is therefore important to identify the optimal pore geometry and use this i...
In this paper we present 2 years of data obtained during the late summer period (September 2003 and September 2004) for the East Siberian Arctic shelf (ESAS). According to our data, the surface layer of shelf water was supersaturated up to 2500% relative to the present average atmospheric methane content of 1.85 ppm, pointing to the rivers as a strong source of dissolved methane which comes fro...
carbon nanostructures are famous structures which are used in several industries such as separation, treatment, energy storage (i.e. methane and hydrogen storage), etc. a successful modeling of activated carbon preparation is very important in saving time and money. there are some attempts to achieve the appropriate theoretical modeling of activated carbon preparation but most of them were almo...
Metal-organic frameworks (MOFs) are potentially useful materials for hydrogen and methane storage. However, the weak interactions between the MOF host and gas guest molecules have limited their storage capacities at elevated temperatures. In this issue, Alkordi et al. [IUCrJ (2017), 4, 131-135] illustrate an example of a porous MOF with a suitable pore size and unique pore surface for enhanced ...
A number of hydrogen-rich van der Waals compounds have recently been discovered and hold promise for improving hydrogen storage technology, but the structure and nature of the intermolecular interactions in many of these materials is unknown. We have determined the previously unknown structure of CH4(H2)4 using a novel combined theoretical and experimental approach. This material contains the l...
Methane hydrate has been extensively studied as a potential medium for natural gas storage and transportation. Due to their high specific surface area, tunable porous structure, chemistry, metal–organic frameworks are ideal materials exhibit the catalytic effect formation process of hydrate. In this paper, hollow ZIF-8 nanoparticles synthesized using hard template method. The used in adsorption...
A common way to store digestate from anaerobic digesters is in open air lagoons. The aim of this study was to investigate whether cooling of digestate before transfer to the storage prevents methane production. Furthermore, if methanogenesis is not prevented, to determine the potential maximum methane slip from an open air lagoon, supplied with heat exchanged digestate from a mesophilic co-dige...
Converting wood to grid quality methane allows to distribute a CO2 free, renewable enery resource in a conventional energy distribution system and use it in transportation applications. Using a previously developed thermo–economic process model for thermochemical production of synthetic natural gas from wood and applying a multi–objective optimisation algorithm, the present paper assesses the p...
