The weight loss characteristics, product distribution and bio-oil composition of co-pyrolysis of rice straw (RS) and Chlorella vulgaris (CV) were investigated by microwave oven. Then, the catalytic effect of activated carbon (AC) and HZSM-5 on these characteristics were studied. Results showed that AC strongly improved co-pyrolysis weight loss characteristics and obtained maximum average weight loss rate (R) at 30% addition with 0.01639 wt.%/s. While HZSM-5 promoted the characteristics as addition was lower than 10%. In the case of compound additives, 20% A7H3 obtained the maximum R (0.01413 wt.%/s). Furthermore, both single AC and HZSM-5 showed negative effect on bio-oil production, while 20% A7H3 (AC/HZSM-5 = 7:3) achieved the maximum production (24%). For bio-oil composition, 30% A10H0 showed strong selectivity for phenol and N-heterocycle and 10% A0H10 showed strong aromatization capacity, and the addition of 20% A7H3 increased the hydrocarbons content from 20.79% to 31.63% compared with the blank group.
采用微波炉研究了稻草（RS）和普通小球藻（CV）共热解的失重特性、产物分布和生物油组成，然后研究了活性炭（AC）和 HZSM-5 对这些特性的催化作用。结果表明，AC 强烈改善了共热解失重特性，在添加量为 30%时获得了最大平均失重率（R），为 0.01639 wt.%/s。而 HZSM-5 则在添加量低于 10%时促进了这些特性。在复合添加剂的情况下，20% A7H3 获得了最大的 R（0.01413 wt.%/s）。此外，单一的 AC 和 HZSM-5 对生物油的产量都有负面影响，而 20% A7H3（AC/HZSM-5=7:3）则实现了最大的产量（24%）。对于生物油的组成，30% A10H0 对苯酚和杂环具有很强的选择性，10% A0H10 具有很强的芳烃化能力，与空白组相比，添加 20% A7H3 使烃类含量从 20.79%增加到 31.63%。
