Abstract

Chromatography and mass spectrometry are used to investigate the chemical composition of industrial light fuel-oil fractions from tar produced by the semicoking of kukersite shale in a Koviter gas generator and a Petroter system based on solid fuel. The content of groups and types of compounds in the samples are compared. The approximate composition of the Petroter-1, Kiviter, and Petroter-3 fractions, respectively, is 42, 43, and 50% hydrocarbons; 40, 41, and 46% oxygen compounds; 7.5, 6.7, and 2.3% sulfur-bearing compounds; and 4.2, 4.9, and 1.5% nitrogen-bearing compounds. By compounding, these fractions are used to produce popular secondary shale oils of grades VKG light and VKG sweet. The shale oils contain less than 0.8% sulfur and have a low pour point (below –17°C). Commercial heating oils perform well in blends with oil-based marine fuels.
