coal coal Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalifiion proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and .

Answer (1 of 8): Fossil fuels are used to produce hydrogen, which in itself is a carbonfree energy source. But the usual production process releases CO2, so the fuel is not really "carbonfree". For example, steam reforming of natural gas has the overall reaction: CH4 + 2 H2O > CO2 + 4 H2 An...

CHAPTER 7
In the process of converting plant material to coal, volitle compounds, such as H 2 O, OH, CH 4, SO2, and many organic acids are expelled. The result is an increase in the relative abundance of carbon in the rock. Coal with a high carbon content burns hotter, and therefore, is more valuable. peat dead plant material that accumulates in swamps.

Chapter 7 COAL
almost all coals is in the range of 12%. Oxygen content is inversely related to carbon content. For example, coals of 65% carbon may contain 30% oxygen, while coals of 95% carbon may contain only 23% oxygen; this is significant because the more oxygen a coal contains, the easier it is to start to burn it, or to achieve its ignition.
