Directional preparation of naphthalene oil-rich tar from Beisu low-rank coal by low-temperature catalytic pyrolysis

Carbon Resources Conversion, 2020
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 ...
