Low-rank coal(LRC)can be converted to high value-added naphthalene and its alkylated derivatives through low-temperature catalytic pyrolysis.In this paper,the catalytic pyrolysis of Beisu LRC in a fixed-bed at low temperature was investigated.And the catalytic effects of HZSM-5,low-temperature carbocoal(LtC),and LtC-HZSM-5 on the content and yield of naphthalene oil were examined.The results showed that the generation of naphthalene oil in low-temperature LRC pyrolysis(LT-LP)process could be improved when LtC(prepared at 550℃)or HZSM-5 was individually used as a catalyst.Compared with sole pyrolysis of raw LRC,the addition of the LtC-HZSM-5 catalyst increased the content of naphthalene oil from 11.19 wt.%to 31.49 wt%.And the yield of naphthalene oil was increased from 1.07 wt%to 5.31 wt%.The reactions of micromolecular hydrogen-containing radicals(⋅MHCR)were optimized by LtC.⋅MHCR could be captured in relatively low-temperature region(200-400℃)and released at high temperature by LtC.The generation of phenolics was inhibited by HZSM-5.As a result,the naphthalene oil-rich tar was obtained through low-temperature LtC-HZSM-5 catalytic pyrolysis of Beisu LRC. 展开更多
