Comportement thermique des schistes bitumineux de timahdit(maroc)

摘要

Thermal behaviour of the Timahdit(Morocco) oil shales.The pyrolysis of the T layer oil shales of Timahdit (Morocco) was carried out for two reasons.Firestly,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 good mother-rock.Their content of polar compounds is more importnat than that of the hydrocarbon compounds.
