摘 要
A pyrolysis experiment was carried out on a Dongying Depression kerogen 8 sample to separate the resin from the oil. Fourier transform ion cyclotron resonance 9 mass spectrometry (FT-ICR MS) with a positive-ion detector was used to detect the 10 relative proportional changes in the compounds of the resin. During the whole 11 pyrolysis experiment, the relative ratio of resin exceed 10% of the soluble component 12 at each temperature point. Five compounds were detected from the resin: N1, N1O1, 13 N1O2, O1, and O2. To research the changes in the proportions of the compounds during 14 pyrolysis clearly, these five compounds were divided into three classes: N1, N1Ox, and 15 Ox. The N1 class has the largest proportion in resin at the beginning of the pyrolysis, 16 while Ox class has the least proportion. And the relationship between the number and 17 the molecular mass of three classes compound was researched. With increasing 18 maturity, the proportion of N1 and the N1Ox class decreased rapidly, while the Ox class 19 * Corresponding author E-mail Address: zouyr@gig.ac.cn (Y. R. Zou) Journal Pre-proof increased slowly. Through researching these resin compounds, it was found that an 20 inversion in the proportions of above three compounds appeared at the end of the oil 21 window. At the same time, we found that the DBE and carbon number of resin 22 compounds have changed obviously during the pyrolysis: the DBE increased, while 23 the carbon number decreased significantly. And the details of the change of each 24 compound have been research. This research extends our knowledge of judging the 25 maturity of crude oil during the pyrolysis through the characteristics of compounds in 26 resin and provides the new index based on resin for the evaluation of thermal 27 evolution stage and hydrocarbon generation capacity of source rocks.
