Thermogravimetric characterization of some iraqi bitumens

The thermogravimetric analysis of various Iraqi bitumens was conducted by heating them in a stream of nitrogen or oxygen gas from room temperature to 800°C at a rate of 20°C mm −1 while recording the partial weight loss at 100°C intervals in addition to the total weight loss Isothermal measurements...

Description
Summary:The thermogravimetric analysis of various Iraqi bitumens was conducted by heating them in a stream of nitrogen or oxygen gas from room temperature to 800°C at a rate of 20°C mm −1 while recording the partial weight loss at 100°C intervals in addition to the total weight loss Isothermal measurements in nitrogen gas were also performed by heating the bitumens from room temperature to 165°C and holding isothermally at this level for 250 min. The resulting thermogravimetric curves provided well-defined data for the characterization and identification of the bitumens studied.
