The intrinsic reaction rate kinetics for the pyrolysis of Michigan Antrim oil shale and the oxidation of the carbonaceous residue of this shale have been determined. The effect of heating rate, and oil shale minerals, particularly iron pyrite on the pyrolysis reaction was also investigated. As a part of the combustion process, the oxidation reactivity of carbonaceous residue prepared at several final pyrolysis temperatures, and the kinetics of chemisorption of oxygen on carbonaceous residue have been determined. Thermogravimetric and differential thermogravimetric techniques were employed in this research. The kinetics of the pyrolysis reaction were determined from both isothermal and nonisothermal rate data. No evidence of any reaction among the oil shale mineral constituents was observed at temperatures below 1173/sup 0/K. However, it was found that the presence of pyrite in oil shale reduces the primary devolatization rates of kerogen and increases the amount of residual char in the spent shale.
