摘要:

以厨余垃圾为原料进行水热液化,考察了反应温度和料液比对产物分布的影响。温度320℃、料液比1:15时,生物油产率最高为16.7%,继续升高温度或降低料液比将促进气体产物生成。与重质原油、常减压渣油相比,生物油氧、氮元素含量较高,热值为32.33~34.82 MJ·kg-1,其中汽油和煤柴油馏分超过50%。利用GC-MS、FT-IR和FT-ICR MS对生物油化学组成、官能团和杂原子组成进行了表征。生物油是一种复杂混合物体系,已检测出烃类、酸类、醛类、酮类、酯类、胺类、酚类、醇类和含氮杂环类等多种物质,对其酸性组分进一步分析显示,含氧组分主要是O2、O3类化合物,含氮组分主要是N1O2、N1O3和N1O4类化合物。

Abstract:

Hydrothermal liquefaction of kitchen waste was processed for bio-oil production. The effects of reaction temperature and solid-liquid ratio on products distribution and bio-oil properties were investigated systematically. The highest bio-oil yield of 16.7% was obtained at 320℃ and 1:15. Further increasing temperature or decreasing solid-liquid ratio would promote gas formation. Bio-oil had higher oxygen and nitrogen content compared to heavy oil or residue oil. Over 50% of bio-oil fraction was in the naphtha, kerosene and AGO range. The higher heating value of bio-oil was 32.33—34.82 MJ·kg-1. Bio-oil was characterized using GC-MS, FT-IR and FT-ICR MS. Bio-oil was a complex mixture composed of hydrocarbons, acids, aldehydes, ketones, esters, amines, phenols, alcohols and N-heterocyclic compounds. Further analysis on the acidic compounds in bio-oil indicated that oxygenated compounds were primarily comprised of O2 and O3 species, nitrogenous compounds were mainly N1O2、N1O3 and N1O4 species.
