Solid metal oxides for carbon capture exhibit reduced adsorption capacity following high-temperature exposure, due to surface area reduction by sintering. Furthermore, only low-coordinate corner/edge sites on the thermodynamically stable (100) facet display favorable binding toward CO2, providing inherently low capacity. The (111) facet, however, exhibits a high concentration of sites. In this work, MgO(111) nanosheets displayed as well ∼65% increase in despite ∼30% sintering (0.77 mmol g–1...
We report the solubility of carbon dioxide in CaCl2(aq) and MgCl2(aq) at molalities (1, 3, 5) mol·kg–1, temperatures (308 to 424) K pressures up 40 MPa. also CO2 a synthetic formation brine containing 0.910 mol·kg–1 NaCl 0.143 KCl over same ranges temperature pressure. The expanded uncertainties 95 % confidence are 0.03 temperature, between (0.08 0.15) MPa bubble pressure 0.00015 mole fraction solution its point. results show strong salting-out effect, whereby declines with increasing...
Many countries have assigned an indispensable role for carbon capture and storage (CCS) in their national climate change mitigation pathways. However, CCS deployment has stalled most with only limited commercial projects realised mainly hydrocarbon-rich enhanced oil recovery. If the Paris Agreement is to be met, then this progress must replicated widely, including hydrocarbon-limited countries. In study, we present a novel source-to-sink assessment methodology based on hubs clusters approach...
A high-pressure flow calorimeter is used to determine isobaric heat capacities for aqueous solutions of some amines such as MEA, DEA TEA, DMAE, MDEA, PZ from T = (293.15 353.15) K and up 25 MPa. The experimental device can measure with an estimated total uncertainty better than 1% a coverage factor k 2. capacity values are analysed in conjunction their temperature pressure dependencies. Furthermore, empirical equations proposed fit functions given conditions, this kind mixtures, obtaining...
This work aims to address the technical concerns related thermodynamic characterization of gas mixtures blended with hydrogen for implementation as a new energy vector. For this purpose, experimental speed sound measurements have been done in gaseous and supercritical phases two binary nitrogen using most accurate technique available, i.e., spherical acoustic resonator, yielding an expanded ($k$ = 2) uncertainty only 220 parts $10^{6}$ (0.022%). The cover pressure range between (0.5 20) MPa,...
This work reports new experimental data on densities and viscosities of (CO2 + n-pentane) n-hexane) mixtures at high pressures temperatures.

Abstract The zeta potential is a measure of electric at the mineral‐electrolyte interfaces. natural sandstones depends on mineralogy, electrolyte pH, concentration, composition, amount dissolved CO 2 , and temperature. We report for first time measured clayey sandstone comprising quartz, kaolinite, illite, albite microcline saturated with NaCl solutions supercritical conditions. Our results demonstrate that potentials in samples conditions are significantly different from similar...
