ABSTRACT

The general properties and distribution of low rank coal occurrences were investigated
in Biga Peninsula, Turkey. Coal occurrences were alternated along with Tertiary clastic,
volcanoclastic and continental units in the peninsula, one of the basic metallic and
industrial mineral potential regions in Turkey. The collected twenty-six lignite samples
from different beds were analyzed and evaluated.
Proximate analyses contain to measure of moisture, ash, volatile matter, and fixed
carbon parameters. The parameters of the original samples showed varieties. The
analyses revealed that moisture content changed from 3.24% to 30.74%, while those of
ash 3.54% - 47.57%, of volatile matter 18.72% - 38.85%, those of fixed carbon were
changed 13.44% - 53.60%. During volatile matter and fixed carbon ratios had
insignificant changes, moisture decreased from west to east of the peninsula. On the
contrary, percent of ash increased through east.
Ultimate or elemental analyses were performed on the low rank coal samples for
encompasses the quantitative determination of carbon, hydrogen, nitrogen, sulfur and
oxygen. Carbon concentration of the specimens was between 19.07% and 69.80%,
hydrogen was 1.94% - 4.61%, nitrogen was 0.38% - 1.62%, and sulfur was 0.46% -
10.85%, oxygen 2.01% - 16.99%. Calorific value of the coals was in 1562 – 6720
Kcal/kg. Carbon ratio rose at the eastern part. In the contrast, oxygen and sulfur reduced
at the same directory. Also, changes of nitrogen and hydrogen ratios could be ignored in
the peninsula.
