The co-pyrolysis characteristics and product yield of Chlorella vulgaris (CV) and polypropylene (PP) under different mixing ratios (10:0, 8:2, 6:4, 5:5, 4:6, 2:8 and 0:10) were studied by microwave oven. Then the effects of different graphite (GP) additions (10%, 20%, 30% and 40%) on the optimum mixing ratio of CV and PP were investigated. The composition of bio-oil was analyzed by GC-MS. The results indicated that the C8P2 (CV/PP = 8:2) group had the best pyrolysis characteristics. The maximum weight loss rate (R) and average weight loss rate (R) of the C8P2 with 30% GP addition achieved the peak value. In the absence of GP, compared with C10P0 group, the contents of nitrogen compounds in bio-oil of the C8P2 group decreased by 21.58%. After adding GP to the C8P2 group, the nitrogen compounds in bio-oil of 30% GP group was 1.93% lower than that in 0% GP group.
研究了不同混合比例（10:0、8:2、6:4、5:5、4:6、2:8 和 0:10）下小球藻（CV）和聚丙烯（PP）的共热解特性和产物产率，采用微波炉进行。然后研究了不同石墨（GP）添加量（10%、20%、30%和 40%）对 CV 和 PP 最佳混合比的影响。通过 GC-MS 对生物油的成分进行了分析。结果表明，C8P2（CV/PP=8:2）组具有最佳的热解特性。添加 30% GP 的 C8P2 的最大失重率（R）和平均失重率（R）达到峰值。在没有 GP 的情况下，与 C10P0 组相比，C8P2 组生物油中含氮化合物的含量降低了 21.58%。向 C8P2 组中添加 GP 后，30% GP 组生物油中的含氮化合物比 0% GP 组低 1.93%。
