摘要

摘要: 对松木和玉米芯快速热解制取的生物油进行储存稳定性实验,经过储存老化后的生物油黏度增大,水分含量和固体颗粒物含量增加,pH值、热值、密度无明显变化。通过GC-MS对储存前后生物油中主要组分进行定量分析表明,生物油经过储存后,羟基丙酮、乙酸、糠醛等主要组分的含量明显下降,而2-甲氧基苯酚、4-甲基-2-甲氧基-苯酚、4-甲基-苯酚的含量有所上升。核磁共振的碳谱分析表明,经过储存后生物油中甲氧基碳和双氧-烷基碳的含量降低,而芳基碳和不饱和碳的含量增大,生物油的芳香度有所提高。

Abstract: A storage stability test was conducted on the bio-oil produced by fast pyrolysis of pine and corncob. The viscosity, water content and solids content of bio-oil increased after storage. However, there were no significant changes in the pH value, heating value and density of bio-oil. The quantitative analysis by GC/MS showed that the content of 1-hydroxy-2-propanone, acetic acid, and furfural were significant decreased. The content of 2-methoxy phenol, 4-methyl-2-methoxy-phenol, and 4-methyl-phenol increased. ¹³C NMR spectral analysis showed that the alkyl carbon and di-O-alkyl carbon content of bio-oil decreased after storage, while the content of aromatic and unsaturated carbon increased. Therefore, the aromaticity of bio-oil increased.
