Parent Coal

Shenfu coal (SFC) was pulverized and modified with planetary ball mill. Maceral separation of the coal was performed by means of density gradient centrifuge in zinc chloride solution. Blends from low density polyethylene (LDPE) and parent coal powder, iron ions loaded coal powder, or floated maceral fractions were prepared in co-rotation twin-screw extruder. Pyrolysis characteristics were investigated based on differential scanning calorimetry (DSC) measurements, apparent activation energies were calculated according to Kissiger and Ozawa methods. It is found that chemical interaction between SFC and LDPE is attributed to their overlapped pyrolysis temperature regions, leading to instant and rapid propagation and termination of macromolecular chains produced in the co-pyrolysis. Iron ions loaded in the coal can facilitate formation of radicals with acceleration in chemical reaction rates. Thermal degradation of LDPE is rate-determining step in co-pyrolysis of the coal and the polyethylene. Maceral fraction floated in 1.25g·cm-3zinc chloride solution is more reactive with polyethylene due to its higher content in aliphatic hydrocarbon and hydrogen, playing a role of excellent hydrogen donor to LDPE in the co-pyrolysis.
