      Polyethylene Aiming to Improve Utilization of Low-Rank Coal.

AB  - The mutual impact of low-quality lignite and high-density polyethylene (HDPE) 
      during open system pyrolysis was investigated, aiming to improve utilization of 
      lignite with simultaneous treatment of HDPE waste. Pyrolysis of lignite, HDPE, 
      and their mixture (mass ratio, 1:1) was performed at temperatures 400, 450, 500, 
      550, and 600  degrees C. Initial substrates and pyrolysis products were characterized by 
      thermogravimetric analysis (TGA), gas chromatography-mass spectrometry (GC-MS), 
      specific carbon isotope analysis of individual hydrocarbons (delta(13)C), Rock-Eval 
      pyrolysis, and elemental analysis. The positive synergetic effect during 
      co-pyrolysis of lignite/HDPE mixture was observed at temperatures >/=450  degrees C, with 
      the greatest being at 500  degrees C. The highest yield of liquid co-pyrolysis products 
      with a similar composition to that of crude oils is also noticed at 500  degrees C. The 
      yields of liquid and gaseous products and quality of pyrolytic products obtained 
      by co-pyrolysis of lignite/HDPE mixture are notably improved compared with 
      pyrolysis of lignite alone. On the other hand, data obtained from pyrolysis of 
      HDPE alone indicate that it cannot be concurrent to well-developed catalytic 
      thermal processes for polymer recycling. However, concerning the huge amount of 
      produced HDPE, at least part of this plastic material can be reused for advanced 
      thermal treatment of lignite, particularly in countries where this low-rank coal 
      represents the main source of energy.
