In this study, compositions of bio-oil and bio-oil with composite additives before and after accelerated aging treatment were analyzed by two-dimensional gas chromatography with time flight mass spectrometry detector (GC × GC-TOFMS) in order to evaluate the effect of the composite additive to the characteristics of bio-oil. The effects of composite additives on bio-oil components and the changes of its components of the bio-oil with or without accelerated aging treatment were compared. A structured distribution of compounds of classification groups was observed in the two-dimensional space. At a signal-to-noise ratio of 1000, more than 3000 peaks were detected by GC × GC-TOFMS, and more than 340 peaks (relative content > 0.02%) were identified after further analysis. After the accelerated aging, the content of various compounds in bio-oil decreased. The content of the classification group and the total content of compounds in the bio-oil with composite additives changed less than that of the crude oil. Before aging, the most abundant substance in bio-oil was 2(5H)-furanone. After aging, the largest content in the original bio-oil is 2(5H)-furanone, and the most abundant substance in the bio-oil with compound additives is Hydroxyacetone. Regardless of whether compound additives are added or not, the composition with the highest content before and after aging of bio-oil is ketones. In crude bio-oil, the substance with the most reduced content was phenols, whose content was reduced by 0.51 wt%. The contents of alcohols, esters, furanones, furans and sugars in the bio-oil with composite additives were increased after storage. The maximum increase was furanones, whose content was increased by 0.15 wt%. Analysis of bio-oil components showed that high added value compounds in bio-oil such as 2(5H)-furanone, Hydroxyacetone and (S)-(+)-2′,3′-Dideoxyribonolactone. The research can provide detailed information on bio-oil composition.

在这项研究中，采用时空质谱检测器（GC×GC-TOFMS）进行二维气相色谱分析了加速老化处理前后生物油和生物油与复合添加剂的组成，以评估生物油和生物油的成分。复合添加剂具有生物油的特性。比较了复合添加剂对生物油成分的影响以及经过或不进行加速老化处理的生物油成分的变化。在二维空间中观察到分类组化合物的结构化分布。在信噪比为1000时，通过GC×GC-TOFMS检测到3000个以上的峰，进一步分析后鉴定出340个以上的峰（相对含量> 0.02％）。加速老化之后 生物油中各种化合物的含量下降。具有复合添加剂的生物油中分类组的含量和化合物的总含量变化小于原油。在老化之前，生物油中最丰富的物质是2（5H）-呋喃酮。老化后，原始生物油中的最大含量为2（5H）-呋喃酮，具有复合添加剂的生物油中含量最高的物质为羟丙酮。无论是否添加复合添加剂，生物油老化前后含量最高的组合物是酮。在粗制生物油中，含量降低最多的物质是酚，酚含量降低了0.51 wt％。储存后，复合添加剂生物油中的醇，酯，呋喃酮，呋喃和糖的含量增加。最大的增加是呋喃酮，其含量增加了0.15重量％。对生物油成分的分析表明，生物油中具有高附加值的化合物，例如2（5H）-呋喃酮，羟丙酮和（S）-（+）-2'，3'-Dideoxyribonolactone。该研究可以提供有关生物油成分的详细信息。
