  • In addition to the mineralogical research, the elemental analysis of the major components of mineral matter in energetic coals has been accomplished. The chemical analysis of the major components confirmed that the mineral matter is a mixture of claystones and carbonates. Calculated dependences of the major components (SiO{sub 2}/Al{sub 2}O{sub 3}, K{sub 2}O/Al{sub 2}O{sub 3}, CaO/MgO) enable to distinguish two types of clay matrix. The mineralogical and chemical research of energetic coals are absolutely necessary for ecological ash utilization.
  • In addition to the mineralogical research, the elemental analysis of the major components and heavy metals of mineral matter in coals has been accomplished. The chemical analysis of the major components confirmed that the mineral matter is a mixture of claystones and carbonates. Calculated dependences of same major components and heavy metals (CaO/MgO, TiO{sub 2}/V, CaO/Zn/Pb). The dependence of mineral matter concentration upon the calculated parameters enable, after coal combustion, to determine the character of obtained ash. Moreover, in those analyzed coals the amount of CaO is higher than the amount of MgO, which is connected with the occurrence notmore » only of dolomite but also of calcite and gypsum. The mineralogical and chemical research of coals are absolutely necessary for ecological ash utilization.« less
  • The combination of mass spectra and EPR allows one to discern the onset through completion of thermally dependent reactions. The studies reported give information on tetrapyrrole diagenesis. Analyses of marine sediments show that chlorins give way to free base porphyrins with aromatization complete at 1000 m depth. Initial homologous series generation of up to 4 members (C/sub 32/ to C/sub 29/) occurs during the chlorin-porphyrin transition. Metallization with either Ni or vanadyl occurs without preference, although nickel porphyrins have a wider distribution. As diagenesis progresses, rupture of the isocyclic ring of porphyrins of the DPEP series results in generation ofmore » the etio series. The porphyrins are the only likely precursors to the petroporphyrins. Petroporphyrins contain no information that relates a particular species to a particular chlorophyll. The maturity of a sediment can be determined by examination of the kerogen and tetrapyrrole pigments. The chemical events surrounding a Miocene intrusion into a Cretaceous shale can be reconstructed.

  • The determination of the organic functionalities of bitumens and kerogens in oil shales have been approached by using chemical methods in which one solid phase is always involved. The Solid Phase Approach to the analysis of complex mixtures comprises three main methods: 1. The Solid Phase Functional Group Analysis Method: used for the analysis (qualitative and quantitative) of soluble compounds (bitumens and tars) is based on colored products produced by chromogenic reaction of specific functional group reagents bounded to the surface of a solid matrix, with the corresponding compounds of the substrate. 2. The Functional Group Marker Method: used formore » the analysis (qualitative and quantitative) of solid substrates (kerogen) is based on the amount of a marker incorporated to the solid phase by means of a reaction between the kerogen and a marked specific functional reagent (soluble). 3. The Solid Phase Extraction Method: used for separating a complex mixture into fractions containing a same functional group. It is based in the reaction (reversible) of a solid phase functional group reagent with the corresponding compounds in a substrate.« less
