Fingerprinting of oil shale by oxidation

Thermogravimetric experiments on oxidation of oil shale in oxygen with kinetic evaluation according to Doyle and Gorbatchev [4-52, 4-53] resulted in considerably varied activation energies for the LTO region (Table 4-157). 

Generally the activation energies obtained from DSC experiments in air are considerably higher than those from experiments in oxygen. As usual the first peak (LTO) and the last one (fuel combustion) can be evaluated without difficulty, whereas the co-ordination of corresponding peaks from experiments with different heating rates in the interval can
