Mössbauer study of products of the thermocatalytic treatment of kerogen-containing rocks

Abstract

© 2017, Allerton Press, Inc. To understand the mechanism of highly efficient catalyst formation from precursors, the active form of an iron-containing catalyst and kerogen samples from the Bazhen formation are studied by Mössbauer spectroscopy and X-ray diffraction analysis. It is established that as a result of phase changes, the multicomponent precursors are transformed into mixed transition metal oxides. It is found that the thermocatalytic effect on pyrite-containing kerogen leads to the formation of pyrrhotite FeS 1 − x and mixed oxides of iron.
