The effects of indigenous carbonate and silicate minerals on the pyrolysis of Green River and Eastern oil shales presented in the following sections. The samples were obtained by a chemical extraction method which was shown to stepwise preferentially disassociate both of these mineral components from the oil shale. In addition, the effect of oil shale richness on pyrolysis yield was determined. Since the major mineral consituent not separated by the chemical extraction procedure was pyrite, a pyrite concentrate was prepared by standard sink-float techniques from the carbonate/silicate-free kerogen concentrate. A silicate-induced pyrolysis effect in conjunction with pyrite is also discussed based on TG-DTG data of the original and chemically extracted samples.
