| 2 | The role of sulfur in the pyrolysis of kerogen显示文摘Sulfur plays an important role in the generation and evolution of hydrocarbon from organic matter. Here, a pyrolysis experiment in closed system was performed on Maoming oil shales kerogen (Type Ⅰ), Maoming oil shales kerogen added with sulfur ether and Maoming oil shales kerogen added with sulphur. The results suggest that the existence of sulfur can result in: (i) higher yield of hydrocarbons generated from the kerogen; (ii) decrease of the temperature for the maximum generation of heavy hydrocarbons (the C15+ fraction) by 20℃; (iii) decrease of the temperature for the maximum generation of the aromatics fraction by 40℃, and (iv) acceleration of the aromatization process. The pyrolysates from kerogen added with sulfur are similar to the heating products of the sulfur-rich kerogen as reported in the literatures. It seems that the sulfur catalysis is also an important factor that can make the sulfur-rich kerogen generate low-mature oil at the earlier diagenesis stage, except for the weakness of the C- | Qin Yan Peng Ping’an Yu Chiling Liu Jinzhong | 2004 | Chinese Science Bulletin2004，49，S1： | 1 |

| 4 | Simulation experiments on secondary thermal stress of biodegraded bituminous sandstones显示文摘Secondary variation of reservoir is a hot problem in petroleum geochemistry field. Several kinds of secondary variations have taken place after the formation of bituminous sandstones in the Tarim Basin including biodegra-dation, washing, dissipation and secondary thermal stress. Biodegraded bituminous sandstones were used in the experiment. Pyrolysis experiment has been performed in a closed system, simulating secondary thermal stress with continual burial of Silurian bituminous sandstones which may cause the changes in molecular compositions, carbon isotope and physical properties of bituminous sandstones. The results are as follows: (i) Gases are mainly product during the experiment and carbon isotope of gas is lighter. (ii) Yield of C6+ hydrocarbon is relative smaller, and yielded oil is mainly light oil. (iii) Chromatogram character of biodegraded oil-sand is similar to that of saturated hydrocarbon in extracts from present-day bituminous sandstones, (iv) Porosity of bituminous sandstones gradually | GONG Se PENG Ping’an LU Yuhong XIAO Zhongyao JIA Wanglu WANG Zhenqi YU Chiling LIU Dehan LU Jialan LIU Jinzhong | 2004 | Chinese Science Bulletin2004，49，S1： | 1 |
| 5 | Thermoluminescence and fission track impact features of rocks显示文摘Results of thermoluminescence (TL) measurement of quartz sandstone before and after impact using a two-stage light gas gun pressure apparatus indicate that, the TL of quartz sandstone decreases as the impact pressure increases, there exists a TL gradient from the outside to the inside around the impacted area, and the induced TL at the same location also has a TL gradient. Impact experiments were conducted under pressures of 12.4, 28.9, 37.8, 51.8, 64.6 and 77.6 GPa, respectively, and fission track density and fission track length before and after the impact were measured. Results demonstrate that the fission track density is decreased and the fission track length is shortened as the impact pressure is increased. | LIU Jingfa LI Dahong YU Chiling SHI Manquan | 2000 | Chinese Science Bulletin2000，45，12： | 1 |
| 6 | Py-GC/MS study of lignin pyrolysis and effect of catalysts on product distribution显示文摘Fast pyrolysis is one of the most promising methods to convert lignin into fuels and chemicals.In the present study,pyrolysis-gas chromatography/mass spectrometry(Py-GC/MS)was used to evaluate vapor phase product distribution of lignin fast pyrolysis.During the non-catalytic pyrolysis process,lignin was pyrolyzed at 400℃,500℃ and 600℃ respectively,finding that the highest yield of aromatic hydrocarbons was obtained at 600℃.Catalytic pyrolysis experiments were also conducted to investigate the effects of catalyst pore structure and acidity on the product distributions.Five different catalysts(HZSM-5,MCM-41,TiO_(2),ZrO_(2) and Mg(Al)O)were applied to lignin catalytic pyrolysis,and the catalytic performance was estimated by analyzing the pyrolytic products.The catalysts were characterized by using X-ray diffraction(XRD),BET,and NH3(CO_(2))temperature programmed desorption.Based on these characterizations,discussion was carried out to explain the formation of the produc distributions.Among the five catalysts,HZSM-5 exhibited the best performance on the formation of aromatic hydrocarbons. | Si Zhan Wang Chenguang Bi Kang Zhang Xinghua Yu Chiling Dong Renjie Ma Longlong Pang Changle | 2017 | International Journal of Agricultural and Biological Engineering2017，10，5： | 1 |
| 7 | Pool-formation and secondary change of biodegraded viscous oils:Case study of reservoir section in the ZhengjiaWangzhuang Oilfield, Jiyang Depression显示文摘It is demonstrated by various geochemical indexes that the Zhengjia-Wangzhuang Oilfield with viscous crude oil in the Jiyang Depression has been sourced from the contribution of matured source rocks in the upper Es4. The principal cause leading to the densification of crude oils would be biodegradation, with the degradation level of crude oils being ranked as 2-8; vertically, the biodegradation level increases from the top to bottom of the oil column, with a distinctive biodegradation gradient occurring. Calculated parameters of sterane, terpane and methyl-phenanthrene have indicated that the source-rock’s maturity of crude oils and asphaltic sands ranges from 0.7 to 0.9, and based on the calculation of Easy Ro model, the temperature of hydrocarbon generation in the source rock would be within 120-140℃, which coincides with the measurements of reservoir inclusions. The measured homogenization temperature would represent the generation temperature of the source rock, and be fairly different from that | WANG Zhenqi, PENG Ping’an, YU Chiling, LU Hong, ZOU Yanrong, ZHANG Linye & LIU Junmin State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China Department of Earth Science, Yangtze University, Jingzhou 434023, China Research Institute of Geology, Shengli Oilfield Co.
