Biomass-Derived Carbon Molecular Sieves Applied to an Enhanced Carbon Capture and Storage Process (e-CCS) for Flue Gas Streams in Shallow Reservoirs

Abstract

It is possible to take advantage of shallow reservoirs (<300 m) for CO2 capture and storage in the post-combustion process. This process is called enhanced carbon capture and storage (e-CCS). In this process, it is necessary to use a nano-modifying agent to improve the chemical-physical properties of geological media, which allows the performance of CO2 selective adsorption to be enhanced. Therefore, this study presents the development and evaluation of carbon sphere molecular nano-sieves (CSMNS) from cane molasses for e-CSS. This is the first report in the scientific literature on CSMNS, due to their size and structure. In this study, sandstone was used as geological media, and was functionalized using a nanofluid, which was composed of CNMNS dispersed in deionized water. Finally, CO2 or N2 streams were used for evaluating the adsorption process at different conditions of pressure and temperature. As the main result, the nanomaterial allowed a natural selectivity towards CO2, and the sandstone enhanced the adsorption capacity by an incremental factor of 730 at reservoir conditions (50 °C and 2.5 MPa) using a nanoparticle mass fraction of 20%. These nanofluids applied to a new concept of carbon capture and storage for shallow reservoirs present a novel landscape for the control of industrial CO2 emissions.

Preparation, Characterization, Evaluation of Neuroprotective Effect, and Related Mechanisms of Phosphatidylserine Emulsion in 5- and 12-Week Old Mice

“…33 The high ζ-potential (negative or positive) is electrostatically stabilized, whereas a particle surface with low ζ-potentials has a tendency to flocculatem. 33,34 In our experiment, the ζpotentials of emulsion were −33.6 mV for the control group, −34.1 mV for the 2% PS emulsion group, and −34.2 mV for the 4% PS emulsion group when the emulsions were freshly prepared at 25 °C, and there were no significant difference among the groups (Figure 2A). After 3 days, the levels of ζpotential were measured; the ζ-potential of the control group presented a lower ζ-potential (−28.0 mV) than those of the 2% PS emulsion group (−30.7 mV) and 4% PS emulsion group (−31.3 mV) at 25 °C (p < 0.001, respectively, Figure 2B).…”

Enhanced Carbon Storage Process from Flue Gas Streams Using Rice Husk Silica Nanoparticles: An Approach in Shallow Coal Bed Methane Reservoirs

“…According to Rodriguez et al the minimum nanoparticle percentages needed to improve the CO 2 sorption capacity are 10 and 20 wt %. Considering this, in this work, CBM was impregnated with the best in class nanoparticles at mass fractions of 10% and 20% by the immersion and soaking method . The nanofluid was developed by dispersing the nanoparticles in deionized water and sonicated at 40 °C for 4 h. CBM was introduced into the nanofluid at 60 °C for 24 h. This method mimicked the reservoir conditions.…”

“…This can be explained by the nanoparticle coming from a biomass byproduct precursor in which other components may interact with CO 2 molecules and/or geological media. 73,109 Moreover, this effect could be related to the CO 2 quadrupole moment, which allows CO 2 −CO 2 interaction at high-pressure conditions and surface interactions. 6 Moreover, it should be remarked that the CO 2 sorption capacities reported in the present work are competitive and, in some cases, superior to those found in the literature, including materials with a more complex synthesis process or more stages.…”

Field Applications of Nanotechnology in the Oil and Gas Industry: Recent Advances and Perspectives

“…Nevertheless, the oil and gas industry is aware of the impact that fossil fuels could have on the environment and the subsequent need for industry decarbonization and the reduction of CO 2 emissions. In this sense, nanotechnology can provide green and cost-effective solutions that help accomplish this purpose through enhanced carbon capture, utilization, and storage under both surface and subsurface conditions. , For example, nanoparticles can enhance the selectivity of the porous medium to CO 2 , avoiding the need of surface separation CO 2 separation from flue gas, which is one of the main sources of cost increases when storage processes are conducted. Another suitable option worthy of implementation under field-scale conditions is the inclusion of double purpose technologies for simultaneous EOR and CO 2 storage, with many efforts made from the enhancement of CO 2 -based foams with nanoparticles, , injection of dispersed nanofluids in a flue gas stream, as well as carbonate water injection in the presence of nanoparticles. − Although these technologies look promising, different challenges arise, such as the CO 2 or flue gas capture transport to the reservoirs in a cost-effective way, as well as the robust injection systems needed here.…”
