“…Furthermore, the 4 : 1 mixture of CO 2 to nbutane, n-octane, and n-dodecane leads to a large difference 4 Geofluids in sorption between the components. This implies that the replacement capacity of CO 2 for the different components is not the same [26].…”

The adsorption properties of shale oil are of great significance to the development of shale oil resources. This study is aimed at understanding the microscopic adsorption mechanism of shale oil in organic nanopores. Thus, a molecular model of organic micropore walls and multicomponent fluids of CO2, C4H10, C8H18, and C12H26 is constructed to investigate the adsorption pattern of multicomponent fluids in organic nanopores under different temperature and pore size conditions. The quantity and heat of adsorption are simulated with the Monte Carlo method, which has been used in previous studies for single-or two-component fluids. The results demonstrate that the ability of CO2 to displace various alkanes is different. Specifically, medium-chain n-alkanes are slightly weaker than light alkanes in competitive sorption, and long-chain n-alkanes are less conducive to competitive sorption. The higher the CO2 sorption ratio, the more the sorption sites occupied by CO2. Thus, it is the best replacement for shale oil. The adsorption quantity of carbon dioxide, n-butane, and n-octane in organic nanopores first increases and then decreases as temperature rises. Meanwhile, the adsorption quantity of n-dodecane decreases firstly and then increases. With the increase in the pore size, the adsorption quantity of carbon dioxide, n-butane, and n-octane in organic nanopores increases while the adsorption quantity of n-dodecane first increases and then decreases. Besides, the model with larger pore sizes is more sensitive to pressure changes in the adsorption of carbon dioxide and n-butane than the model with smaller pore sizes. The heat of adsorption is CO2, C12H26, C8H18, and C4H10 in descending order. All are physical adsorption. Moreover, the adsorption quantity of all four components mixed fluid in the organic matter nanopores is positively correlated with the heat of adsorption.

“…Then, CO is removed from the gaseous mixture of hydrogen, carbon monoxide, and water vapor by involving it into the water-gas shift reaction with the formation of CO 2 and its separation on adsorption and membrane installations [3,4]. The production of lowcarbon-footprint hydrogen requires not only separation but also utilization of CO 2 , both by disposal or use in oil extraction [5] and by use as chemical feedstock. The latter processes, which include dry reforming of methane [6], dehydrogenation of alkanes [7], and high-temperature and low-temperature electrolysis of СО 2 to СО or, in the presence of water, to syngas [8,9], as a rule, are powerconsuming and in many cases lead to the formation of СО, which should be subsequently converted in traditional chemical processes.…”

The feasibility of biphenyl hydrogenation with syngas for hydrogen purification and binding with the aim of its transportation was demonstrated. Specific features of the hydrogenation of biphenyl as a promising organic hydrogen carrier using unsupported Ni–Mo sulfide catalysts were studied. In particular, the influence of temperature, reaction time, presence of water in the system, and Н2/СО gas mixture composition on the substrate conversion and selectivity with respect to products was examined. The highest conversion and the maximal hydrogen uptake are reached at 380°С in 6–8 h. The dispersed catalysts are active in biphenyl hydrogenation at the CO concentration in the Н2/СО gas mixture of up to 50 vol %, and H2O can act in this case as an in situ hydrogen source owing to the occurrence of the water-gas shift reaction.

“…The captured CO2 can be released out with high concentration by temperature swing. As for the storage process, CCS could also be combined with the current fossil fuel extraction processes, for example, the underground injection of CO2 for crude oil enhanced oil recovery 16,18 . However, the high costs of separation, enrichment 19 and transportation of CO2 20 limit the deployment of CCS.…”
