The evaporative emissions of anthropogenic volatile organic compounds (AVOCs) are sensitive to ambient temperature. This sensitivity forms an air pollution-meteorology connection that has not been assessed on a regional scale. We parametrized the temperature dependence AVOC fluxes in quality model and evaluated impacts surface ozone Beijing–Tianjin–Hebei (BTH) area China during summer 2017. dependency drove enhanced simulated ozone-temperature 1.0 1.8 μg m–3 K–1, comparable driven by biogenic VOC (1.7 2.4 K–1). Ozone enhancements temperature-induced increases were localized their point emission relatively more important urban areas than rural regions. inclusion temperature-dependent our improved sensitivities days exceedance. Our results demonstrated importance pollution its heretofore unrepresented role pollution–meteorology interactions.

Cooperative and Bifunctional Adsorbent‐Catalysts Materials for In‐situ VOCs Capture‐Conversion

ChemPlusChem, Год журнала: 2023, Номер 89(5)

Опубликована: Дек. 20, 2023

Abstract Volatile organic compounds (VOCs) are gases that emitted into the air from products or processes and major components of pollution significantly deteriorate quality seriously affect human health. Different types metals, metal oxides, mixed‐metal polymers, activated carbons, zeolites, metal‐organic frameworks (MOFs) mixed‐matrixed materials have been developed used as adsorbent catalyst for diversified VOCs detection, removal, destruction. In this comprehensive review, we first discuss general classification removal outline historical development bifunctional cooperative adsorbent‐catalyst air. Subsequently, particular attention is devoted to design strategies materials, along with detailed discussions on latest advances these reaction mechanisms, long‐term stability, regeneration processes. Finally, challenges future opportunities environmental implementation identified outlined intent providing insightful guidance fabrication more efficient systems in future.

Preparation of CYCU‐3/MCM‐41 Composites and Adsorption Properties for n‐Hexane

ChemistrySelect, Год журнала: 2024, Номер 9(41)

Опубликована: Окт. 28, 2024

Abstract Adsorption method is one of the effective technologies for treating VOCs. Compared with activated carbon, silicon‐based materials have well‐ordered pore structure, good thermal stability and non‐flammability. In this paper, CYCU‐3/MCM‐41 composites were prepared by hydrothermal through mixing MCM‐41 powder in situ. The nitrogen adsorption isotherms, saturation cyclic adsorption/desorption curves n‐hexane on experimentally measured. results displayed that (3) exhibited largest BET specific surface area (1631 m 2 /g). And its capacity was 776 mg/g, which 19.4 % higher than MCM‐41, 1.42 times 2.64 molecular sieve. kinetic fitting showed pseudo‐first order model can more precisely embody process composites, W‐M intraparticle diffusion confirmed not only control step rate composites. addition, regenerative over 98.9 after ten desorption cycles n‐hexane, showing performance excellent structural stability, proving broad application prospect field VOCs treatment.
