落叶松木材生物油组分分析和表征

为了更加合理、高效的利用落叶松木材快速热解生物油与酚醛树脂制备新型胶黏剂，必须对快速热解生物油的主要组分进行全面、透彻的分析。本文采用气质联用仪（GC-MS）对生物油组分进行定性分析；采用气相色谱（GC）重点对生物油中的酚类物质进行定量分析；采用傅立叶变换红外光谱（FT-IR）对生物油旋转蒸发后得到的物质（重质油）进行结构表征。通过分析得到生物油组分主要包括羧酸类、醚类、酚类、醇类、醛类、烷烃类等有机化合物。结果表明，不同工况条件下生物质油中酚类物质质量分数为4%～15%，最大值为14.15%。

Analysis and characterization of component for bio-oil from larchwood

Component of bio-oil form Larchwood by fast pyrolysis technique was completely analyzed in order to make more rational and high efficient use of new adhesive agent making by the bio-oil of Larchwood and phenolic resin. Qualitative determination of bio-oil of Larchwood was performed by Gas Chromatography-Mass Spectrometric (GC-MS) method. The study on quantitative analysis of the polyphenols in the bio-oil was used by Gas Chromatography (GC). Fourier transform infrared spectroscopy (FT-IR) was applied to characterize structure of heavy oil that were obtained through the bio-oil evaporated by rotary. Components of the bio-oil were disclosed through analyzing, which included acids, ethers, phenols, alcohols, aldehydes, alkanes, as such complex organic compounds. Results revealed content of phenols in bio-oil were ranged from 4% to 15%, maximum content was 14.15% under different treatment conditions.
