Oil shale samples from the M, X, Y, and T-Zones of the Timhadit reserves in Morocco have been tested with a Thermogravimetric Analyzer (TGA) to provide nonisothermal weight loss data. Analysis of this data has provided several of the kinetic values necessary for the understanding and modeling of the thermal decomposition mechanisms of kerogen pyrolysis and inorganic carbonate decomposition in Timahdit oil shale. Several methods of data analysis were developed which utilize both the differential and integral forms of the reaction rate equations. In addition, the relationship between the temperature at which the maximum reaction rate occurs and the heating rate was derived for the first-order reactions. This relationship can be used to determine the activation energy and frequency factor using the weight loss data obtained at constant heating rate. These methods are discussed and the analytical procedures, calculations, and results are presented for the determination of the kinetics of kerogen pyrolysis and inorganic carbonate decomposition in Moroccan oil shale from the Timahdit reserves.
