Comportement thermique des schistes bitumineux de Timahdit (Maroc)

Abstract The pyrolysis of the T layer oil shales of Timahdit (Morocco) was carried out for two reasons. Firstly, using gas chromatography, the contents of the various gases given off during this pyrolysis have been determined. Then, according to Rock–Eval pyrolysis results of the crude oil shales and their isolated kerogen, it has been concluded that these oil shales are located towards the beginning of the evolution of type II, have a marine origin and present qualities of a good mother-rock. Their content of polar compounds is more important than that of the hydrocarbon compounds.
