dc.description.abstract | Twenty-seven gases and sixteen rock wastes from the thermal active Rymer coal waste
dump were collected. The composition and origin of gaseous, liquid, and solid pollutants emitted
during the self-heating process and the development of these processes with time were established.
Gases were subjected to determination of molecular and stable isotope (d13C and d2H) composition.
Rock-Eval pyrolysis and pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) were applied
for evaluation of the quantity and molecular composition of pyrolysates released during the heating
of rocks in temperatures from 100 to 650 C. The main products of Py-GC-MS are released between
350 and 650 C, namely alkanes, aromatic hydrocarbons, and aromatic alcohols. These components
were also recorded in Py-GC-MS products of samples collected from the dump surface. Besides
the high-molecular-weight organic compounds, in emitted gases CO2, CO, gaseous hydrocarbons,
and S-compounds were recorded. The stable isotope data indicated that methane was generated
mainly during the low-temperature thermogenic process, but a share of the microbial-originated gas
was visible. The source of the CO2 was the oxidation of organic matter. The gaseous S-compounds
were products of high-temperature decomposition of sulphides and organic S-compounds. The
hydrocarbon and CO contents of the emitted gases proved to be good indicators for tracking of the
self-heating processes. | pl_PL |
