Abstract:
Taking advantage of the higher peak capacity, resolution, sensitivity and selectivity of two-dimensional gas chromatography with time flight mass spectrometry detector (GC×GC/TOFMS), a detailed qualitative and quantitative analysis of crude bio-oil (CB) and aged bio-oil (AB) was performed in order to analyze the chemical change during bio-oil storage. The total compounds numbers of CB and AB detected by GC×GC/TOFMS were 2728 and 2212 respectively when the signal to noise ratio (S/N) was set to 1000. And about 340 peaks (area > 0.02%) were tentatively identified. Chemical components were ranked according to their contents: ketones > phenols > furanones > acids > ester > aldehydes > furans > aromatics > alcohols > sugars. After the fast aging test of crude bio-oil, all kinds of compound content reduced. The maximum reduction was phenols, which was reduced by 0.51wt %. A structured distribution of compounds of classes was observed in the two dimensional space. The result of these bio-oils analyzed by GC×GC provided a detailed knowledge of their composition change during storage and bio-oils might be employed for the production of high value-added chemicals.
