Co-pyrolysis of Chlorella vulgaris (CV) and Oily sludge (OS) under different mixing ratios were investigated by microwave furnace. NiO, activated carbon (AC) and their 1:1 compound (N1A1) with different additions (5%, 10%, 15% and 20%) were selected as microwave additives to study the effects on optimum mixing ratio of co-pyrolysis. The results indicated that mixing ratio of CV/OS = 1:1 (C1O1) was optimum for co-pyrolysis. Besides, 10% AC was optimal on improving pyrolysis characteristics of the C1O1 group. The most significant synergistic interaction of NiO and AC occurred in the 10% N1A1 group. Moreover, hydrocarbons in bio-oil of the C1O1 group increased by 31.84% compared with theoretical values, while nitrogenous, oxygenated compounds decreased by 74.18% and 19.01%. Addition of 10% N1A1 in the C1O1 group increased aliphatic hydrocarbons by 22.44%, and decreased nitrogenous, oxygenated compounds by 41.79% and 36.58%. Overall, 10% N1A1 was conducive for the C1O1 group to obtain high-quality bio-oil.
不同混合比例下的小球藻（CV）和含油污泥（OS）共热解通过微波炉进行了研究。选择 NiO、活性炭（AC）及其 1:1 混合物（N1A1）作为微波添加剂，添加量分别为 5%、10%、15%和 20%，以研究对共热解最佳混合比例的影响。结果表明，CV/OS=1:1（C1O1）的混合比例最适合共热解。此外，10%的 AC 对改善 C1O1 组的热解特性最有利。NiO 和 AC 的协同作用在 10%N1A1 组中最为显著。此外，与理论值相比，C1O1 组生物油中的烃类增加了 31.84%，而含氮、含氧化合物分别减少了 74.18%和 19.01%。在 C1O1 组中添加 10%的 N1A1 可使脂肪族烃增加 22.44%，并使含氮、含氧化合物分别减少 41.79%和 36.58%。总的来说，10%的 N1A1 有利于 C1O1 组获得高质量的生物油。
