In the present study, we have proposed a novel flash pyrolysis process of coal by utilizing plastics as radical donors. This process is related to recycle of plastic wastes and is based on an intimate contact of pulverized coal and polyolefins by a light heat-treatment.(1) Even when polyolefin was impregnated on pulverized coal by mechanical mixing, yields of monomers and light aromatic compounds such as BTX in flash pyrolysis were effectively increased. This suggests that hydrogen and hydrocarbon radicals were transferred from polyolefin to coal in a short reaction period.(2) Polyolefins, which were pyrolyzed lightly at 360-420ﾟC for 1 hour, were dissolved in THF,and coal-polyolefin composites were produced by adding a pulverized coal in the THF solution of polyolefins. This procedure further enhanced the contact between polyolefin and coal, and increased the production of tar at a higher yield, compared with that obtained by the pyrolysis of each components separately.(3) When polyolefin was lightly cracked in a nitrogen atmosphere containing a small amount of oxygen, the pyrolysis temperature of polyolefin-coal mixture was decreased at least by 200ﾟC.The CO2 yield was only 2vol%.

在本研究中，我们利用塑料作为塑料供体的煤炭闪光过程。在360-420°C下，浸渍的液化剂有效增加了（2）个，溶解在THF的煤炭中。 ，与在含有少量氧气的氮气大气中轻轻破裂时，与每种组分的热解相比，增加了焦油的产量，与每种成分的热解相比。混合物至少降低200°C。二氧化碳产量仅为2vol％。
