英文摘要In this paper, to investigate the catalytic pyrolysis behavior of coal (XJ) volatiles over two hematite (HA and HB), a double-layered fixed-bed reaction apparatus, which was easy to separate coal and catalysts was employed to measure the pyrolysis tar yield, and the composition of pyrolysis tar and gas was investigated by GC-MS and GC. The results indicated that both hematite A and hematite B reduced the tar yield and caused an increase in CH4, CO2 and H-2 output. Analysis of the chemical composition of tar indicated that XJ had a high content of pitch (46.39 %). At the same time, the addition of HA and HB decreased the pitch content by 7.59 and 8.88 %, respectively. Then, the change in the hematite chemical composition and physical structure after catalytic pyrolysis was characterized by XRD, TEM, XPS, SEM and N-2 adsorption-desorption. Furthermore, a catalytic mechanism was proposed to illustrate the transformation of pyrolysis tar over hematite. Fe atoms and lattice oxygen are the decisive factors in the bond cleavage of pyrolysis tar. Fe atoms can break the C-C and C-H bonds of aliphatic hydrocarbons, while lattice oxygen can promote C-O bond cleavage and produce CO2.
