Using gas-chromatography, the authors developed a unique technique called 'NPgram' to characterize the hydrocarbon fuel oil. 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 paraffins (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, NPgram (C-NPgram) actually represents a boiling point distribution, when it is applied for fuel oils composed of aliphatic compounds. In this work we applied this ONPgram technique to characterize coal derived oils which are mostly composed of aromatics. And analogous to C-NPgram, the carbon number distributions of S, N, Cl and O-compounds in coal derived oils were also shown. We defined them by 'S-NPgram', 'N-NPgram', 'Cl-NPgram' and 'ONPgram'. The NPgrams of these heterogeneous compounds were obtained by plotting the amount of heterogeneous compounds determined by a GC-AED (Atomic Emission Detector) against the carbon number (n).
