Nannochloropsis sp. (a kind of green microalga) residue was pyrolyzed without catalyst or with different amount of HZSM-5 catalyst in a fixed bed reactor in nitrogen flow. The effects of pyrolysis parameters such as temperature and catalyst-to-material ratio on product yields were studied. The bio-oils obtained were analyzed by elemental, GC-MS and FTIR analysis. The results indicated that the bio-oils from catalytic pyrolysis of Nannochloropsis sp. residue (BOCP) had lower oxygen content (19.5 wt.%) and higher heating-value (32.7 MJ kg(-1)) than those obtained from direct pyrolysis (BODP) which had an oxygen content of 30.1 wt.% and heating-value of 24.6 MJ kg(-1). The BODP mainly consisted of long carbon chain compounds with various terminal groups (LCTG), while the BOCP mainly consisted of aromatic hydrocarbons. These properties of bio-oils demonstrated that the Nannochloropsis sp. residue can be used as a renewable energy resource and chemical feedstock.
微拟球藻（一种绿藻）残渣在氮气流动中未经催化剂或使用不同量的 HZSM-5 催化剂在固定床反应器中进行热解。研究了热解参数（如温度和催化剂与原料的比例）对产物产率的影响。通过元素分析、GC-MS 和 FTIR 分析对获得的生物油进行了分析。结果表明，与直接热解（BODP）相比，微拟球藻残渣催化热解（BOCP）获得的生物油的含氧量（19.5wt.%）更低，热值（32.7MJkg(-1)）更高，BODP 的含氧量为 30.1wt.%，热值为 24.6MJkg(-1)。BODP 主要由具有各种末端基团的长链化合物（LCTG）组成，而 BOCP 主要由芳烃组成。这些生物油的性质表明，微拟球藻残渣可用作可再生能源和化学原料。
