Fast microwave-assisted catalytic co-pyrolysis of Chromolaena odorata (C. odorata) and soybean soapstock with HZSM-5 as an ex-situ catalyst was investigated. Effects of catalytic temperature, feedstock: catalyst ratio and C. odorata: soybean soapstock ratio on the yield and composition of the bio-oil were discussed. Results showed that catalytic temperature greatly influenced the bio-oil yield. Co-pyrolysis of C. odorata and soybean soapstock improved the bio-oil yield, and the maximum bio-oil yield of 55.14% was obtained at 250 °C. However, the addition of HZSM-5 decreased bio-oil yield but improved the quality of bio-oil. Moreover, the proportion of oxygen-containing compounds decreased dramatically with the addition of soybean soapstock. The C. odorata: soybean soapstock ratio of 1:2 and feedstock: catalyst ratio of 2:1 were the optimal condition to upgrade the bio-oil. In addition, the resulted biochar contained various essential elements and could be used as soil repair agent.
快速微波辅助催化共热解臭牡丹（C. odorata）和大豆皂脚与 HZSM-5 作为原位催化剂进行了研究。讨论了催化温度、原料与催化剂的比例以及臭牡丹与大豆皂脚的比例对生物油产率和组成的影响。结果表明，催化温度对生物油产率有很大影响。臭牡丹和大豆皂脚的共热解提高了生物油的产率，在 250°C 时获得了最大生物油产率 55.14%。然而，HZSM-5 的添加降低了生物油的产率，但提高了生物油的质量。此外，添加大豆皂脚后，含氧化合物的比例显著下降。臭牡丹：大豆皂脚的比例为 1:2，原料与催化剂的比例为 2:1 是生物油升级的最佳条件。此外，所得生物炭含有各种必需元素，可用作土壤修复剂。
