固定床反应器中生物质/废塑料共热解制备燃料油

通过热重分析不同生物质（木屑和秸秆）单独热解以及与塑料（PP和dcPVC）共热解时的热解行为，研究了生物质与塑料共热解过程中的协同作用。在固定床反应器中考察了塑料的含量对生物质/塑料共热解的影响，最后通过元素分析和GC-MS对所得生物油进行了分析。研究结果表明：生物质和塑料共热解过程中存在明显的协同作用。木屑和PP共热解过程中的协同作用最为显著，当PP含量为80%时，所得生物油的产率最高，明显高于两者单独热解得到的生物油。元素分析和GC-MS分析结果表明：木屑和PP所得生物油的含氢量较高，所得到生物油的热值与石化燃油的相近。

Co-pyrolysis of biomass and waste plastic for biofuel in fixed-bed reactor

Thermal pyrolysis of different biomass (sawdust，straw) and plastic (polypropylene，poly vinyl chloride) and synergistic effects of co-pyrolysis of biomass and plastic were investigated with TGA. In fixed-bed reactor the influence of plastic content on co-pyrolysis of biomass and plastic was discussed，and the produced bio-oil was analyzed with elemental analysis and GC-MS. The results showed that significant synergy was present in the co-pyrolysis process of biomass and plastic，especially in the co-pyrolysis process of sawdust and polypropylene the synergistic effect was the most prominent. When the content of polypropylene was 80%，bio-oil yield was the highest，obviously higher than that of separate pyrolysis. And the results of elemental and GC-MS analysis showed that the bio-oil had a higher hydrogen content and its calorific value was equal to that of the crude oil equivalent.
