探讨了污水原料组成对水热液化生物原油性质和理化特性的影响。螺旋藻、猪粪和消化污泥在HTL条件（300°C，10- 12 MPa和30分钟反应时间）下转化。生物原油产率范围从9.4%（消化污泥）到32.6%（螺旋藻）。尽管所有产品油的热值（32.0-34.7MJ/kg）都类似，但更详细的表征显示生物原油化学性质存在显著差异。原料组成影响所识别的单个化合物以及生物原油官能团化学。分子量随碳水化合物含量的增加而增加，螺旋藻<猪粪<消化污泥。在沸点分布和长支链脂肪族含量中观察到类似的趋势。这些发现表明HTL原料组成的重要性，并强调在考虑生物油用途和升级要求时需要更好地了解生物原油化学。
This study explores the influence of wastewater feedstock composition on hydrothermal liquefaction (HTL) biocrude oil properties and physico-chemical characteristics. Spirulina algae, swine manure, and digested sludge were converted under HTL conditions (300°C, 10–12MPa, and 30min reaction time). Biocrude yields ranged from 9.4% (digested sludge) to 32.6% (Spirulina). Although similar higher heating values (32.0–34.7MJ/kg) were estimated for all product oils, more detailed characterization revealed significant differences in biocrude chemistry. Feedstock composition influenced the individual compounds identified as well as the biocrude functional group chemistry. Molecular weights tracked with obdurate carbohydrate content and followed the order of Spirulina<swine manure<digested sludge. A similar trend was observed in boiling point distributions and the long branched aliphatic contents. These findings show the importance of HTL feedstock composition and highlight the need for better understanding of biocrude chemistries when considering bio-oil uses and upgrading requirements.
