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,

Energy‐Efficient Induction Carbonization: Tailoring Pore Structures in Hard Carbon Anodes Toward Enhanced Electrochemical Performance

Carbon Energy, EarlyView.
ABSTRACT Hard carbon (HC) is currently the predominant anode material for sodium‐ion batteries; however, its practical application is still limited by insufficient initial Coulombic efficiency (ICE) and plateau capacity. Meanwhile, conventional HC production relies on energy‐intensive carbonization processes with considerable carbon emissions. Here, an

Beyond Furnaces: Harnessing In Situ Joule Heating for Efficient C1 Catalysis

Carbon Energy, EarlyView.
Joule‐heated catalysis directly converts electrical energy into localized heat within conductive catalysts, overcoming the heat‐transfer limitations of conventional furnaces. This review summarizes recent advances in C1 molecule conversion, including CO2 methanation, reforming for hydrogen production, and HCHO/CO oxidation, while highlighting ...

Rich‐Electronic Interface Promoting Hydrogen‐Bond Reversible Formation for Ultra‐Stable and Energy‐Efficient Catalytic CO2 Capture

Carbon Energy, EarlyView.
Bridging micro–macro scales, a biomass‐derived Ni@C interface creates electron‐rich sites and hydrogen‐bond proton‐relay pathways, tuning interfacial charge and reversible hydrogen bond to enhance carbon capture capacity. Verified by in situ spectroscopy, multi‐scale simulations, and long‐term industrial testing, this system enables low‐temperature and
