Abstract
The composition of narrow fractions of shale gasoline extracted from LTC (low-temperature carbonization) tar is determined by rectification and gas chromatography–mass spectrometry. The LTC tar is derived from high-sulfur Mishor Rotem shale. The fractions considered are <77°C, 77–85°C, 85–105°C, 105–115°C, 115–130°C, and 130–150°C. The selective extractants N,N-dimethylformamide and N-methylpyrrolidone are used in extractive rectification of the gasoline, toluene, and xylene fractions of the LTC shale tar. The material balances are determined, and the composition of the distillates and bottoms obtained are determined. The results show that it is possible, in principle, to extract thiophene and its homologs from these fractions by extractive rectification using selective extractants.
