Carbon capture and sequestration (CCS) is a three-tier process- carbon capture, transport storage. The consists of pre-combustion, oxy-combustion post-combustion capture. Transport CO2 most viable through pipelines. biotic CO2storage occurs terrestrial or oceanic pathways can be simulated naturally artificially. abiotic/geologic storage achieved sequestering in depleting/depleted hydrocarbon reserves, deep saline aquifers mineral carbonation. At the district level, 64 out 641 districts (2013 government reports) accounted for ∼ 60% total emissions. Controlling emissions comes with challenge sustainable socio-economic growth country- demanding task economy. Indian organizations have made international collaborations. India holds substantial geological potential its basaltic rocks, coal seams, depleted oil soils, sedimentary basins. this point, no / clean development mechanism projects are operational country. next 10-15 years would very crucial to attain technological advancement deploy large-scale CCS projects.

Due to the enormous increase in number of metal-organic frameworks (MOFs), combining molecular simulations with machine learning (ML) would be a very useful approach for accurate and rapid assessment separation performances thousands materials. In this work, we combined these two powerful approaches, ML, evaluate MOF membranes MOF/polymer mixed matrix (MMMs) six different gas separations: He/H2, He/N2, He/CH4, H2/N2, H2/CH4, N2/CH4. Single-component uptakes diffusivities were computed by grand canonical Monte Carlo (GCMC) dynamics (MD) simulations, respectively, simulation results used assess permeabilities selectivities membranes. Physical, chemical, energetic features MOFs as descriptors, eight ML models developed predict adsorption diffusion properties MOFs. Gas membrane 5249 31,494 MMMs predicted using models. To examine transferability models, also focused on computer-generated, hypothetical (hMOFs) permeability selectivity 1000 hMOF/polymer MMMs. The that accurately uptake He, H2, N2, CH4 gases will significantly accelerate These direct extensive experimental efforts computationally demanding fabrication analysis materials offering high performance target separation.

Clean Technologies, Год журнала: 2022, Номер 4(4), С. 1193 - 1207

Опубликована: Ноя. 17, 2022

One of society’s major current challenges is carbon dioxide emissions and their consequences. In this context, new technologies for (CO2) capture have attracted much attention. these utilization (CCU). This work focuses on the latest trends in a holistic approach to utilization. Absorption, adsorption, membranes, chemical looping are considered CO2 capture. Each technology described, its benefits drawbacks discussed. For use dioxide, various possible applications CCU starting with agriculture proceeding conversion into fuels (catalytic processes), chemicals (photocatalytic polymers, building supplies. decades, has been used industrial processes, such as CO2-enhanced oil recovery, food industry, organic compound production (such urea), water treatment, and, therefore, flame retardants coolants. There also several CO2-utilization at stages development exploitation, electrochemical fuels, supercritical CO2. At end review, future opportunities discussed regarding machine learning (ML) life cycle assessment (LCA).

The Application of Biochar for CO₂ Capture: Influence of Biochar Preparation and CO₂ Capture Reactors

Industrial & Engineering Chemistry Research, Год журнала: 2023, Номер 62(42), С. 17168 - 17181

Опубликована: Июнь 29, 2023

This work investigates three types of biochar (bamboo charcoal, wood pellet, and coconut shell) for postcombustion carbon capture. Each is structurally modified through physical (H2O, CO2) chemical (ZnCl2, KOH, H3PO4) activation to improve capture performance. Three methods (CO2 adsorption isotherms, CO2 fixed-bed adsorption, thermogravimetric analysis) are used determine the capacity. The results show that a more than 2.35 mmol·g–1 (1 bar, 298 K) capacity was achieved using activated samples. It also demonstrated performance by depends on multiple surface textural properties. A high area pore volume resulted in an enhanced Furthermore, O*/C ratio width negative correlation with biochars.

TAMOF-1 is a robust, highly porous metal-organic framework built from Cu2+ centers linked by L-histidine derivative. Thanks to its high porosity and homochirality, has shown interesting molecular recognition properties, being able resolve racemic mixtures of small organic molecules in gas liquid phases. Now, we have discovered that also offers competitive performance as solid adsorbent for CO2 physisorption, offering promising adsorption capacity ( > 3.8 mmol g-1) CO2/CH4 Ideal Adsorbed Solution Theory (IAST) selectivity 40) at ambient conditions. Moreover, the material exhibits favorable kinetics under dynamic conditions, demonstrating good stability high-humidity environments minimal degradation strongly acidic media. We identified key interactions within combination structural (neutron diffraction), spectroscopic theoretical analyses which conclude dual-site mechanism with majority adsorbed occupying empty voids channels without strong, directional supramolecular interactions. This very weak dominant binding opens possibility low energy regeneration process convenient purification. These features identify viable solid-state realization affordable biogas upgrading.
