Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide

Chemistry – A European Journal, EarlyView.
Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.

Influence of Particle Size, Moisture, and Cloud Density on Wood Dust Ignition

Chemie Ingenieur Technik, EarlyView.
The ignition and combustion of particle clouds are strongly affected by particle interactions. This study uses spectroscopy to examine effects of particle size, water content, and cloud density. Results show ignition delay rises with larger size and density, whereas combustion duration depends mainly on water and density due to moisture‐driven ...

Experimental investigation of the effects of altitude on the performance of a non-sprayed porous burner

AIP Advances
A self-sustained burner was built for diesel oil without an atomizer using metal fiber felt as an evaporator. The effects of firing rate, excess air coefficient, and altitude on the temperature distribution, NOx emission, and CO emission were studied ...

Kinetic Characterization and NOx Reduction Mechanism of Mixed Ammonia-Hydrogen Combustion in Cyclone Combustor

发电技术
ObjectiveAmmonia plays a key role in achieving the “dual carbon” goal, but ammonia has a low combustion rate and high NOx emission. In order to improve the combustion rate, a method of ammonia-hydrogen blending combustion was proposed.MethodsThe combined
