Abstract

Coal samples of three ranks are investigated: long-flame (D) coal, long-flame gas (DG) coal, and gas (G) coal. The composition and properties of the coal samples and their thermal-destruction products are studied by the following methods: proximate analysis, ultimate analysis, petrographic analysis, thermogravimetry, and chromatography and mass spectroscopy. In low-temperature thermal destruction, solid, liquid, and gaseous products are formed. The liquid products consist of a complex mixture of saturated and aromatic hydrocarbons. Normal and branched n-alkanes and n-alkenes are also identified. The molecules of the aromatic hydrocarbons contain 1–5 benzene rings. The molecules CO2, H2, H2S, NH3, HCN, C4H5N, C6H12, CH4, and CO are identified in the gaseous products by mass spectrometry.
