A Review on the Recent Scientific and Commercial Progress on the Direct Air Capture Technology to Manage Atmospheric CO₂ Concentrations and Future Perspectives

Energy & Fuels, Год журнала: 2023, Номер 37(15), С. 10733 - 10757

Опубликована: Июнь 12, 2023

Climate change has been linked to industrial and commercial activities caused by exploitation of fossil fuels for energy needs over a century now. A significant rise in greenhouse gas (GHG) emissions, majorly CO2, reported the last few decades. Global climate necessitates mitigation atmospheric CO2 levels suitable margins using capture mechanisms. Direct air (DAC) technology is most efficient way mitigate or reduce emissions capturing carbon dioxide directly from air. It imperative that DAC be ramped up quickly order meet goal global temperature below 2 °C next 30 years. This review focuses on specifics various techniques, pilot projects, facilities deployment. seen substantial technical improvement recent years, with firms already functioning industry upmarket potential. There are about 19 plants operation across world, absorbing around 0.01 Mt CO2/year. article discusses technologies used companies, future potential, life cycle assessment, as well economic viability worldwide installation these facilities. The paper provides details application sorbents including nanomaterials current advances DAC. Lastly, outlook perspectives also presented concluding remarks.

Direct Air Capture and Integrated Conversion of Carbon Dioxide into Cyclic Carbonates with Basic Organic Salts

ACS Sustainable Chemistry & Engineering, Год журнала: 2023, Номер 11(26), С. 9613 - 9619

Опубликована: Июнь 23, 2023

Direct air capture and integrated conversion is a very attractive strategy to reduce CO2 concentration in the atmosphere. However, existing capturing processes are technologically challenging due costs of low CO2. The efficient valorization captured could help overcome many techno-economic limitations. Here, we present novel economical methodology for direct that able efficiently convert from into cyclic carbonates. new approach employs commercially available basic ionic liquids, works without need sophisticated expensive co-catalysts or sorbents under mild reaction conditions. atmospheric was by IL solution (0.98 molCO2/molIL) and, subsequently, completely converted carbonates using epoxides halohydrins potentially derived biomass as substrates. A mechanism evaluated, which helped identify relevant intermediates based on halohydrins, consequently, 100% selectivity obtained methodology.

Capturing CO2 from air (DAC) is becoming an attractive technological route to face the climate crisis. This paper reviews existing research efforts integrate DAC with conversion technologies transform captured into chemicals or fuels. The approach can potentially lead net zero carbon emissions, thus being of interest in a circular economy framework. A growing amount has been devoted combination conversion, leading creative strategies which start be scaled up. In this review, we have critically analysed approaches by degree process integration. From point view intensification, integration both capture and reaction same vessel equipment energy cost savings besides other synergistic effects. vessel, occur either consecutive stages change feed spontaneously cascade without changing conditions. As side effect, benefits entailed intensification different levels may decisive driving force for widespread deployment DAC. discusses ongoing perspectives guide researchers promising new field.

Self‐Sorting of Interfacial Compatibility in MOF‐Based Mixed Matrix Membranes

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(24)

Опубликована: Апрель 9, 2024

Metal-organic framework (MOF)-based mixed matrix membranes (MMMs) have shown great promises to overcome the performance upper limit of polymeric for various gas separation processes. However, properties MMMs largely depend on MOF-polymer interfacial compatibility which is a metric difficult quantify. In most cases, whether MOF filler and polymer make good pair not revealed until transport experiments are performed. This because there lack characterization techniques directly probe compatibility. this work, we demonstrate self-sorting method rank interface among several pairs. By mixing one with two polymers in an MMM, demixing will form domains. The particles preferably partition into "preferred" domain due their higher affinity. scanning different pairs, from high low can be obtained. Moreover, based ranking, it was also found that highly compatible suggested by corresponds more predictable MMM performance.
