摘要

使用丙胺溶液对裙带菜孢子叶残渣进行水热液化，分析了水热液化后生物油、水溶性物质和固体残渣的成分。在丙胺浓度1.5 mol·L-1、反应温度240℃、料液比1：10的条件下得到生物油的最大产率为39.81%（质量）。生物油通过GC-MS和FT-IR进行分析，结果表明成分包含醇类、烷类、酯类、酸类、酚类和酰胺类等，并存在C=C、C=O、O-H等化合键。水溶性物质通过HPLC和GC-MS进行分析，结果表明主要产物为酸类物质。固体残渣通过XRD进行分析，结果表明水热液化后纤维素的结晶度降低。最后对丙胺进行回收，在温度100℃条件下回收率达到92.56%。

Abstract

Hydrothermal liquefaction of Undaria pinnatifida residue with n-propylamine solution was investigated

and the components of bio-oil

water-soluble substances and solid residue were analyzed. The highest bio-oil yield of 39.81% (mass) was obtained with n-propylamine concentration of 1.5 mol·L-1

temperature 240℃

solid-to-liquid ratio 1:10. The results of GC-MS and FT-IR showed that the bio-oil consisted of alcohols

alkanes

esters

acids

phenols and amides

and also contained C=C

C=O

O-H and other chemical bonds. The results of HPLC and GC-MS analysis indicated that the main products of water-soluble substances were acids. Furtherly

XRD analysis of solid residue showed that the crystallization of cellulose decreased after hydrothermal liquefaction. The effect of temperature on the recovery of n-propylamine was also studied

and the recovery rate reached 92.56% at 100℃.
