Using gas-chromatography, the authors developed a unique technique called 'NPgram' to characterize the hydrocarbon fuel oils. The notation 'NPgram' stands for Normal Paraffin gram. It is obtained by plotting the weight percent of a group of hydrocarbons, which are located within the range of retention values of two successive normal parafins (Cn-1 and Cn), against the carbon number (n). As the carbon number (n) corresponds to the boiling point range of a group of compounds, C-NPgram actually represents a volatility distribution of the fuel oils. In this work we applied the NPgram technique to characterize the coal derived oil. Analogous to C-NPgram, the volatility distribution of S-, N-, Cl- and O-compounds in coal derived oils were shown by 'S-NPgram', 'N-NPgram', 'Cl-NPgram' and 'O-NPgram'. The NPgrams of these heterogeneous compounds were obtained by plotting the contents of heterogeneous compounds determined by a AED-GC (Atomic Emission Detecter) against the carbon number (n).
