摘要: Abstract Soluble organic matter in Dongming lignite was obtained via thermal dissolution using isopropanol as the solvent and named DLIP. Catalytic conversion of DLIP carried out Co-Mo/γ-Al2O3 catalyst to reach hydrogenation, hydrocracking heteroatom removal. corresponding catalytic products were analyzed by Fourier transform-infrared spectroscopy (FT-IR), gas chromatography/mass spectrometry (GC/MS) Orbitrap mass (Orbitrap MS). According FT-IR data, contents alcohols phenols increased with reaction temperature due cleavage C O bonds macromolecules coal. The soluble its hydrogenation GC/MS classified into 10 classes, MS used obtain componential distribution containing compounds. Moreover, weighted-mean double bond equivalent (DBE) value carbon number (CN) calculated. decrease DBE/CN after demonstrated ring opening reactions bridge-bonds.
