Investigation of NO reduction mechanism of nitrogen-impregnated biomass across wide temperature range

Fuel Processing Technology
Traditional denitrification methods for coal-fired power boilers face challenges like reduced flue gas temperature at low loads, decreased efficiency of existing denitrification devices, and increased ammonia consumption.

Testing our understanding of Arctic denitrification using MIPAS-E satellite measurements in winter 2002/2003 [PDF]

Atmospheric Chemistry and Physics, 2006
Observations of gas-phase HNO3 and N2O in the polar stratosphere from the Michelson Interferometer for Passive Atmospheric Sounding aboard the ENVISAT satellite (MIPAS-E) were made during the cold Arctic winter of 2002/2003.

Denitrification pathways and rates in the sandy sediments of the Georgia continental shelf, USA

Geochemical Transactions, 2005
Denitrification in continental shelf sediments has been estimated to be a significant sink of oceanic fixed nitrogen (N). The significance and mechanisms of denitrification in organic-poor sands, which comprise 70% of continental shelf sediments, are ...

Warming can boost denitrification disproportionately due to altered oxygen dynamics. [PDF]

PLoS ONE, 2011
BACKGROUND: Global warming and the alteration of the global nitrogen cycle are major anthropogenic threats to the environment. Denitrification, the biological conversion of nitrate to gaseous nitrogen, removes a substantial fraction of the nitrogen from ...

Denitrification in carbonate aquifers: a literature review

GEUS Bulletin
Denitrification is the most important process for nitrate removal in groundwater. Although carbonate aquifers are important for drinking water supply, the denitrification process in these systems is less understood than for unconsolidated sedimentary ...

Rates and Pathways of N2 Production in a Persistently Anoxic Fjord: Saanich Inlet, British Columbia

Frontiers in Marine Science, 2019
Marine oxygen minimum zones (OMZs) support 30–50% of global fixed-nitrogen (N) loss but comprise only 7% of total ocean volume. This N-loss is driven by canonical denitrification and anaerobic ammonium oxidation (anammox), and the distribution and ...

Research progress of autotrophic denitrification technology of sulfur, iron and sulfur-iron based electron donors

Gongye shui chuli
Autotrophic denitrification technology has the advantages of no additional carbon source, low sludge yield and low cost. It is one of the promising technologies for deep denitrification of low C/N wastewater under the dual-carbon background.

Contribution of Particulate and Mineral-Associated Organic Matter to Potential Denitrification of Agricultural Soils

Frontiers in Environmental Science, 2021
Water-extractable organic carbon (WEOC) is considered as the most important carbon (C) source for denitrifying organisms, but the contribution of individual organic matter (OM) fractions (i.e., particulate (POM) and mineral-associated (MOM)) to its ...
