The isolation of saturated hydrocarbons from free bitumen coal and also from bound bitumen coal in the region of Kosovo is descriled in this study. n-Alkanes from C17-C21 to C33-C35, with A7-C29 being dominant, were identified by gaschromatographic analysis of the free bitumen. This distribution indicated the terrestrial origin of the coals and a low level of carbonification. The decreasing values of the CPI of the bound bitumen (1.08-2.77), composed to the CPI values of the free bitumen (2,04-3,90) and a shift of the dominant n-alkane (A7-C29 -> A7-C23) are a result of the higher "maturity" level of the n-alkanes in bound bitumen.
