Low-Temperature Co-Pyrolysis Products of Low Rank Coal and Enteromorpha

Abstract:

Co-pyrolysis characteristics of low rank coal (LRC) and enteromorpha (EN) in different proportins were studied in a dry distillation equipment. The results show that he maximum tar yiled of blends was 11.39% with a EN ration of 30%, which increased by 28.61% compared to LRC pyrolysis alone. In the co-pyrolysis tar ,the alkanes’ content was 48.66% and the phenolic was 9.12%, which was significantly higher than the content of the corresponding components of the original tar. The H/C ratio was increased by 9.87%. It indicated the pyrolysis tar became lighter on some degree. While the contents of CH₄ and H₂ in the pyrolysis gas were increased. SEM analysis showed the surface of co-pyrolysis semi-coke became rough and formed obvious center cracks. The heat value of co-pyrolysis semi-coke was higher than that of semi-coke from LRC.
