|Here we can see
a typical thermogravimetric analysis.
The chart shows weight loss percent as the material is heated without
oxygen present. The dotted line shows
the rate of weight loss in percent per min per 10 degrees C. The step curve between 300 and 400
represents the exothermic zone. Each biomass produces a different chart. Now
if we take these to charts and overlap them, let us see what happens.
