Volatile Matter - an overview | ScienceDirect Topics

Volatile matter (VM) is the percentage loss in mass, adjusted for moisture, when coal is heated out of contact with air under standard conditions. In this test, 1 g of sample is placed into a lidded crucible (to prevent ingress of air), which is placed in a furnace at 900 °C for 7 min or 950 °C if using the ASTM method. Moisture in the analysis sample is determined concurrently.

States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an ...
