Abstract Marine biomass and terrestrial biomass have distinct compositions and structures. In order to understand the effect of feedstock difference on deoxy-liquefaction products, the experiments were performed with marine biomass (Enteromorpha prolifera, Giant kelp, Undaria pinnatifida) and terrestrial biomass (cotton stalk, sweet potato vine, plane leaves) for comparison of product yields and compositions. GC–MS results showed that the liquid oils from marine biomass were rich in alkanes (36.64–39.18%) and nitrogenous compounds (7.07–11.61%). While, the terrestrial biomass oils were rich in phenolic compounds (36.02–40.55%) and aromatic hydrocarbons (6.36–12.31%). The solid char properties were further characterized by FTIR, XRD and SEM analysis, respectively and their potential applications were also discussed. All the results suggested that the types of feedstock have a significant effect on the biomass deoxy-liquefaction products.

海陆生物质脱氧液化对比研究

摘要 海洋生物质和陆地生物质具有不同的组成和结构。为了解原料差异对脱氧液化产品的影响，对海洋生物质（浒苔、巨海带、裙带菜）和陆生生物质（棉秆、甘薯藤、梧桐叶）进行了产品对比实验。产量和成分。GC-MS 结果表明，来自海洋生物质的液体油富含烷烃（36.64-39.18%）和含氮化合物（7.07-11.61%）。而陆生生物质油富含酚类化合物（36.02-40.55%）和芳烃（6.36-12.31%）。分别通过 FTIR、XRD 和 SEM 分析进一步表征了固体炭的性质，并讨论了它们的潜在应用。
