The microwave-assisted co-pyrolysis of Chlorella vulgaris (CV), wood sawdust (WS) and their blends with additives were investigated. There was a higher liquid and solid yield with silicon carbide (SiC) than activated carbon (AC) in most of samples. Microwave-assisted pyrolysis with additives behaved a positive effect on deoxygenation and aromatization, but not apparent denitrification. With the increase of CV proportion, aromatic hydrocarbons decreased, but aliphatic hydrocarbons increased using AC. High selectivity of phenols was reached at the sample of WS (relative content as 43.6%) using SiC; High selectivity of alkenes was reached at the sample of CV (relative content as 31.2%) and alkanes at the blend sample of 70% CV and 30% WS (relative content as 9.45%). Bio-oil and biochar from microwave-assisted pyrolysis of WS had higher calorific value than that of CV both with AC and SiC. Calorific value of bio-oil decreased by 33.3% after mixing CV with WS.
研究了小球藻（CV）、木屑（WS）及其与添加剂混合物的微波辅助共热解。在大多数样品中，碳化硅（SiC）比活性炭（AC）具有更高的液体和固体产率。添加剂的微波辅助热解对脱氧和芳构化有积极作用，但对脱氮作用不明显。随着 CV 比例的增加，使用 AC 时芳烃减少，但脂肪族烃增加。在 SiC 作用下，WS 样品中酚类的选择性达到 43.6%；在 SiC 作用下，CV 样品中烯烃的选择性达到 31.2%，在 70%CV 和 30%WS 的共混样品中烷烃的选择性达到 9.45%。WS 的 AC 和 SiC 辅助微波热解得到的生物油和生物炭的热值均高于 CV。CV 与 WS 混合后，生物油的热值降低了 33.3%。
