SEPARATION OF MINERAL MATTER FROM SEYITOMER KUTAHYA LOW RANK LIGNITE

Abstract

Itis well known chat minerals in Coal inhibit che effective utilizacion of coals. lf the ash-free coal can be produced in a reasonable price, it will contribute utilization not only to solve the ash problems, bur also to bring the high efficiency af caal anareay In chic stude tha rarauai af winemal va arene Trnesins Se see SEG ys oN GUS Study, the romoval of minesgl atts the Seyitémer-Kiitahya low rank lignite was investigated under various extraction conditions. Determination of ash, moisture and volatile macter was performed according to ASTM Standards. Lignite sample was a alyzed to determine its elemental composition and calorific value, Tae furictional group compositional analysis of lignite sample was invest i spectrophotmetry. Experimental investigation for removal of from Seyitémer-Kiitahya low rank lignite by using inor solvents such as HCl, NaOH and CH,OH. In this experirnentai studies; it was examined that the effect of the extraction temperature (25, 50, 75 and 100 °C), the extraction time (1,3and5 hour) and solvent concentration (19, 15, 20 % acid; 2, 4, 8 % NaOH; 5, 10, 20% CH.OH) on the removal of minera: At che end of demineralization, 80-95 % of the Original mineral conzenz of che low rank lignite was removed, Demineralizacion has affected che calorific value Positively according to the calorific value determination resulcs.
