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.

库兹涅茨克盆地煤的低温热破坏：产品组成

摘要

研究了三个等级的煤样：长焰 (D) 煤、长焰瓦斯 (DG) 煤和瓦斯 (G) 煤。通过以下方法研究煤样及其热破坏产物的成分和性质：近似分析、极限分析、岩相分析、热重分析、色谱和质谱分析。在低温热破坏中，会形成固体、液体和气体产物。液体产品由饱和烃和芳烃的复杂混合物组成。还鉴定了正构和支链正构烷烃和正构烯烃。芳香烃分子含有 1-5 个苯环。分子 CO ₂ , H ₂ , H ₂ S, NH ₃、HCN、C ₄ H ₅ N、C ₆ H ₁₂、CH ₄和CO 在气态产物中通过质谱鉴定。
