چکیده انگلیسی
The detailed characterisation of middle distillates is essential for a better understanding of reactions involved in refining process. Owing to higher resolution power and enhanced sensitivity, comprehensive two-dimensional gas chromatography (GCÂ ÃÂ GC) is a powerful tool for improving characterisation of petroleum samples. The aim of this paper is to compare GCÂ ÃÂ GC and various ASTM methods - gas chromatography (GC), liquid chromatography (LC) and mass spectrometry (MS) - for group type separation and detailed hydrocarbon analysis. Best features of GCÂ ÃÂ GC are demonstrated and compared to these techniques in terms of cost, time consumption and accuracy. In particular, a new approach of simulated distillation (SimDis-GCÂ ÃÂ GC) is proposed: compared to the standard method ASTM D2887 it gives unequal information for better understanding of conversion process.
