Fragment ion-functional group relationships in organic aerosols using aerosol mass spectrometry and mid-infrared spectroscopy

Satoshi Takahama, Amir Yazdani, Imad El Haddad, Nikunj Dudani

Aerosol mass spectrometry (AMS) and mid-infrared spectroscopy (MIR) are two analytical methods for characterizing the chemical composition of OM. While AMS provides high-temporal-resolution bulk measurements, the extensive fragmentation during the electron ...

Characterization of primary and aged wood burning and coal combustion organic aerosols in an environmental chamber and its implications for atmospheric aerosols

Satoshi Takahama, Nikunj Dudani, Imad El Haddad, Amir Yazdani

Particulate matter (PM) affects visibility, climate, and public health. Organic matter (OM), a uniquely complex portion of PM, can make up more than half of total atmospheric fine PM mass. We investigated the effect of aging on secondary organic aerosol (S ...

Fine Particle Iron in Soils and Road Dust Is Modulated by Coal-Fired Power Plant Sulfur

Athanasios Nenes

Transition metal ions, such as water-soluble iron (WS-Fe), are toxic components of fine particles (PM2.5). In Atlanta, from 1998 to 2013, a previous study found that WS-Fe was the PM2.5 species most associated with adverse cardiovascular outcomes. We exami ...

Enhancing the operational flexibility of thermal power plants by coupling high-temperature power-to-gas

François Maréchal, Jan Van Herle, Ligang Wang, Yang Sun

The increasing penetration of intermittent renewable power challenges the stability of the electrical grid, thus coal power plants are usually required to extend the operation range by reducing the minimum load. This work proposes a concept of coupling sol ...

Health effects of power plant emissions through ambient air quality

Christine Choirat

Coal burning power plants are a frequent target of regulatory programmes because of their emission of chemicals that are known precursors to the formation of ambient particulate air pollution. Health impact assessments of emissions from coal power plants t ...

Quantification of amorphous siliceous fly ash in hydrated blended cement pastes by X-ray powder diffraction

Karen Scrivener, Ruben Anton Snellings, Xuerun Li

X-ray powder diffraction (XRPD)-based quantitative phase analysis is a common technique for studying the hydration of cementitious systems. Hydrated cements often comprise several amorphous or nanocrystalline phases. This paper presents a protocol for the ...

On the Assessment of the CO2 Mitigation Potential of Woody Biomass

François Maréchal, François Richard Vuille, Emanuela Peduzzi, Victor Codina Gironès

Woody biomass, a renewable energy resource, accumulates solar energy in form of carbon hydrates produced from atmospheric CO2 and H2O. It is, therefore, a means of CO2 mitigation for society as long as the biogenic carbon released to the atmosphere when de ...

Online Detection of Selenium and Its Retention in Reducing Gasification Atmosphere

Christian Ludwig, Andrea Testino, Mohamed Tarik, Adrian Hess

The emission of selenium from coal gasification processes can cause harm to the environment and downstream equipment. With upcoming legislation, reliable detection as well as control of such gas species become crucial. This study therefore addresses the de ...

Review of fly ash inertisation treatments and recycling

Rudolf Paul Wilhelm Jozef Struis

Fly ash (FA) is a by-product of power, and incineration plants operated either on coal and biomass, or on municipal solid waste. FA can be divided into coal fly ash, obtained from power plant burning coal, flue gas desulphurisation FA, that is, the by-prod ...
