Fossil Energies

Description

fossilenergies-calorymetry

Fossil fuels are mainly used for their heat content through combustion. In a first step, it is needed to classify the different fossil fuels, especially in term of fixed carbon. Heat capacity has to be known in the industrial process. Pyrolysis of fossil fuels can also be industrially used. A good knowledge of the gases emitted during the thermal transformation is needed.

Classification: Due to the large rank of solid fuels, especially coal, a classification based on the composition of the sample is needed. For coal, a standard thermogravimetric determination gives the ratio of moisture, volatiles, fixed carbon and ash.

Characterization: Pyrolysis is a thermal transformation that is very common with fossil fuels. As it produces different types of gases, the combination between thermogravimetry (TGA) and evolved gas analysis (EGA) is very helpful for such an investigation.

Combustion: DSC and calorimetry are used to investigate the combustion of fossil fuels and measure the corresponding heat of combustion. As a stoechiometry in oxygen is needed in such a pressure, the sample has to be heated under an adequate pressure of oxygen.

Heat capacity: If the calorific value of fossil fuel is of first importance, the knowledge of the value of its heat capacity is also necessary to establish the heat balance for the thermal process.

Wax appearance temperature (WAT) is easily determined by low temperature DSC
