Research output: Contribution to journalArticlepeer-review


A unique technique to characterize the hydrocarbon fuel oil was developed and called "NPgram", for Normal Paraffin gram. This technique was applied to characterize coal derived oil mostly composed of aromatics. The NPgrams of S, N, Cl, and O-compounds in coal derived oils were shown. The NPgrams of these heterogeneous compounds were obtained by plotting the amount of heterogeneous compounds determined by GC-AED (Atomic Emission Detector) against the carbon number.
