Angewandte Chemie International Edition, EarlyView.By combining polarization‐resolved IRRAS with hybrid HSE06 DFT calculations, we establish site‐specific vibrational fingerprints, adsorption geometries, and binding energies for CO on wide‐band‐gap MgO surfaces. Low‐coordinated Mg4c2+ step‐edge sites, rather than terrace Schottky defects, are identified as the dominant binding and reactive sites, with ...

SO3 formation during oxy-coal combustion - Presentation
, 2010 presentationIn oxy-coal combustion, an oxygen and carbon dioxide mixture, rather than air, is used to burn the coal. Many studies to date have focused on the formation of NOx under oxy-coal combustion conditions; however, the formation of sulfur species,

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).
