Hydrogen nitrogen content

Jackson et al. [9] have presented calculations of thermal efficiency for this simple hydrogen fuelled CBT cycle, first with very low nitrogen content in the fuel and secondly with 50/50 hydrogen/nitrogen. For the first case they find relatively little change in... 

Solid fuels, unlike gases and liquids, are entirely characterized by their composition. For example, coal can be characterized by its carbon, hydrogen, oxygen, sulfur, and nitrogen content. The water and mineral content of coal are also important means of differentiating coals from various sources.

Elemental analysis of fuel oil often plays a more major role that it may appear to do in lower-boiling products. Aromaticity (through the atomic hydrogen/carbon ratio), sulfur content, nitrogen content, oxygen content, and metals content are all important features that can influence the use of residual fuel oil. 

However, from the nitrogen content a lower percentage of quinone oxygen was calculated than from the hydrogen uptake during reduction with sodium borohydride. Other double bonds can react with diazomethane as well (74) ... 

In this chapter, the biogeochemical cycling of organic matter is discussed from the perspective of its carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur content.
