“…Hence, the CO 2 sorption capacity decreases the sorption capacity: RSi-TE < RSi-DE < RSi-U < RSi-EM. Also, while comparing the effect of amine loading on all surface modifiers, the addition of 1, 3, and 5 wt % amine to silica nanoparticles leads to an increase in the average CO 2 sorption capacity; however, a further increase in the amine loading to 5 wt % will cause steric hindrance and agglomeration of particles, which have a negative impact on the diffusion of CO 2 reducing the CO 2 sorption capacity due to blockage of the porous structure (i.e., 5 wt % < 1 wt % < 3 wt %). , Therefore, the CO 2 maximum sorption capacity was similarly obtained for all 3 wt % N-source impregnated silica systems, increasing as RSi-TE3 < RSi-DE3 < RSi-U3 < RSi-EM3. These systems presented the highest sorption performance and were evaluated for selective CO 2 sorption from flue gas streams.…”

“…On the other hand, some research has established silica-modified nanomaterials such as amine-functionalized as ideal sorbents for selective separation of CO 2 from a mixture of gases due to their reversible reaction with CO 2 . The interaction between acidic CO 2 and other molecules as basic amine groups could increase the CO 2 uptake, enhancing their sorption capacity, which have been widely studied in the scientific literature in the capture process. − Although the silica nanomaterials developed in the literature mentioned above were not applied to carbon storage in reservoirs of sandstone and CBM, these tunable characteristics have great potential to be involved in this kind of process and, additionally, to promote an environmentally friendly process with a minor footprint carbon. To the best of our knowledge, this is the first study using amine-functionalized biomass-derived silica nanoparticles to improve the chemical-physical properties of carbon bed methane to enhance its CO 2 selective sorption based on a CCS process.…”

Carbon capture and storage (CCS) is considered a key process to reach net-zero emission by the 2050 aim of limiting global warming. Coal bed methane (CBM) is considered potential geological reservoirs for underground CCS due to the CO2–CH4 exchange feasibility by adsorptive phenomena. Global implementation has been focused only on deep reservoirs to provide methane recovery. Thus, this work proposes a modified CCS process based on silica nanoparticle inclusion for shallow CBM reservoirs (<300 m). The nanomaterials were evaluated at high pressure in two main stages including i) CO2 sorption on a single CO2 stream and ii) CO2 selectivity on a flue gas stream (N2–CO2 mixture). This work includes silica nanomaterial synthesized from rice husk as agro-waste sources with better technical-economic feasibility framed in a circular economy to reduce costs and maximize the use of available resources. Rice husk silica (RSi) nanoparticles were doped with 1.0, 3.0, and 5.0 wt % of urea (Si–U), diethylamine (Si-DE), triethylamine (Si-TE), and ethylenediamine (Si-EM) to enhance the CO2 sorption. First, CO2 sorption was evaluated at 30 °C and between 0.084 and 3 MPa using a CO2 stream to determine the best-doped amount of each N-source. Then, the best nanoparticles were used to impregnate CBM at 10 and 20 wt %, and the subsequent CO2 storage on the flue gas stream (70% v/v N2 and 30% v/v CO2) was done. The results showed that CO2 sorption on RSi increases with the N-group coating in the order RSi-DE < RSi-TE < RSi-U < RSi-EM. Also, the best-doped amount for each N-source was 3 wt %. For CBM impregnation, the nanofluid containing 20 wt % of RSi-EM3 presented the best yield increasing the CO2 sorption from 0.05 to 0.75 mmol g–1, meaning an increase of more than 1000% in the sorption capacity.

CO 2 -enhanced coalbed methane (CO 2 -ECBM) technology helps to store CO 2 while producing a clean source of energy (CH 4 ) through the sorption process. This technique can sequester much CO 2 at low temperatures and pressures while recovering CH 4 , which will help offset the associated costs, such as capturing injection gases, drilling and completion infrastructure, compression, and injection expenses. This review paper critically analyzes the CO 2 sequestration potentiality in deep unmineable coal seams. The results revealed that, despite several researchers' insights from proposed concepts, experimental data, modeling and simulations, and pilot tests, there are no reported full field CO 2 -ECBM technology applications for CO 2 sequestration and CH 4 recovery because implementing the projects is uneconomical. Also, CO 2 sequestration and CH 4 recovery effectiveness on coal seams depend on wettability changes of the CO 2 −H 2 O−coal system. The identified research gaps and challenges in this paper are going to help various researchers and shareholders in conducting extra investigations toward full field application of CO 2 sequestration while simultaneously producing a clean source of energy (CH 4 ) in deep unmineable coal seams to meet the Paris climate summit agreement to achieve net zero emissions by 2050 and a maximum global temperature rise of 1.5 °C.
