Geophysics (2021) 86 (3): U31–U37.
.... We explain it by competitive sorption of methane and water in the coal pore space; methane under pressure replaces part of the adsorbed water from micropores so that this water can easily form hydrate. The difference in the acoustic properties of frozen and hydrate-bearing coal samples is important...

...Garri Gaus; Reinhard Fink; Alexandra Amann-Hildenbrand; Bernhard M. Krooss; Ralf Littke ABSTRACT Gas storage capacity estimates of shales are routinely assessed using laboratory data from unconfined methane sorption and porosity measurements. In this study, the stress dependence of the methane...

...-pressure gas sorption (LPGS) of CO 2 and N 2 and mercury intrusion capillary pressure (MICP) measurements. The combination of the LPGS and MICP methods demonstrates that the pore volumes of these shales are mainly associated with mesopores, whereas the micropores and macropores are relatively undeveloped...

... mechanism of sequestration in these geochemical conditions. This speciation explains efficient scandium recovery through mild metal-lurgical treatments of supergene lateritic ores. The specificities of scandium sorption mechanisms are related to the preservation of adsorbed scandium in million-years old...

..., account for colloidal transport, and/or account for a wide range of surface sorption models. To test T2CPI and demonstrate its capabilities, carbonate reservoirs within the Dollar Bay Formation (DBF) of the South Florida Basin were chosen for a case study, with the ultimate objective of understanding...

... a pelletization process. Thickening of the material during pelletization influences sorption capacity negatively due to diffusing limitations, while the lack of an additional binder may result in a material of low mechanical durability. In this study, pressure pelletization experiments with fly ash zeolite were...

... in ores as well as during mineral processing. Moreover, Sr-Ca-dominant APS minerals exhibit preferential sorption of Pb from fluid sources, in the form of both common Pb and 210 Pb, for the first time revealing potential pathways for 210 Pb elimination and reduction from ore processing streams. 14 5...

... sorption and immobilization of elements and is favourable for secondary enrichment in gold and silver. It leads to immobilization of elements that further form new mineral phases or become partitioned between existing phases. On the other hand, very high concentrations of water-soluble and oxidizable...

... was the same as the natural clinoptilolite. In the second part of this work, the ultrasonic-assisted sorption of Cu 2+ ions from polluted water by CNS was investigated. These experiments were optimized with response surface methodology based on central composite designs. The effects of initial pH of solution...

... for oil retention in the Niobrara shale oil system in the Denver Basin so that zones of enrichment can be recognized. In general, the retention of petroleum in organic-rich shales is controlled mainly by the sorption capacity of its OM ( Baker, 1962 ; Tissot et al., 1971 ; Stainforth and Reinders, 1990...

..., i.e., oxygen, is in short supply. Likewise, none of the models mentioned above sufficiently accounts for organo–mineral interactions by only considering sorption–desorption dynamics. Soil minerals are important factors in determining soil aqueous chemistry. Minerals, microbial metabolic byproducts...
