CuFeO2 was prepared by hydrothermal synthesis method and applied in catalytic hydrocracking of low-rank coal under mild conditions,and the reaction mixture was extracted with petroleum ether.The composition and structural characteristics of soluble portion were analyzed with gas chromatograph/mass spectrometer(GC/MS).The results showed that the CuFeO2 catalyst prepared by hydrothermal synthesis was nano-sized CuFeO2 particles.The compounds detected with GC/MS could be divided into four categories,including aliphatic hydrocarbons,arenes,oxygen-containing compounds,and nitrogen-containing compounds,of which arenes had the highest relative content.The research provides theoretical guidance for the clean and efficient conversion of low-rank coal under mild conditions.
