Fourteen vitrinite reflectance profiles from the Tarim Basin,NW China,show that the vitrinite reflectance profiles of individual wells follow a faulted and dislocated dual-stage pattern in the eastern section of the Tazhong Uplift and in the Tabei *** reflectance values in these profiles change sharply at the unconformity beneath the Lower carboniferous Bachu or Upper Devonian Donghetang Formations,where the overlying Triassic to carboniferous strata are still in a mature phase within the "liquid oil window".However,the underlying Lower Paleozoic reached the overmature phase beyond the "liquid oil window" towards the end of the Silurian,or in the Early Devonian at the *** the vitrinite reflectance profiles are attributed to a continuous,single-stage pattern in the western section of the Tazhong Uplift,in which the Lower Paleozoic is also in an overmature phase,their overmaturity would have been achieved relatively late in geological *** stratigraphic thermohistory has the following implications to regional geoevolution:(1) The overmature Lower Ordovician to cambrian strata in the eastern section of the Tazhong Uplift and in the Tabei Uplift,as well as in the Manjiaer Depression,could not have acted as the source kitchen for normal oil(so-called black oil);(2. The dissimilarity in vitrinite reflectance profiles between the eastern and western sections of the Tazhong Uplift reveals Early Paleozoic paleotectonic features,i.e.,lower at the east and higher at the west,whereas recent tectonic features formed since the late Paleozoic are in reverse,i.e.,higher in the east and lower at the west;(3) Reconstruction of the denuded thickness of sediments overlying the Lower Ordovician strata suggests reconsideration on the paleotectonic features in the Tarim Basin;(4) Based on the sustained duration of the "liquid oil window" for overmature source beds,it is predicted that the Suntuoguole Lower Uplift between the Awati and Manjiaer Depressions is a

石油学报（石油加工） 2001年第1期17卷 18-24页

作者： Atsushi ISHIHARA, Wei hua QIAN, Toshiaki KABE (Department of Chemical Engineering Faculty of technology, Tokey University of Agriculture and technology, 2.2. 1 Nakacho, Koganei, Tokyo 184 8588, Japan) Tokey University of Agriculture and technology 日本 184 8588

To meet the specification of sulfur and aromatic contents in diesel fuel, it is necessary for refiners to develop a new catalyst with high activity of hydrodesulfurization and hydrogenation. In the present study, the properties of noble metal catalysts for hydrodesulfurization and hydrogenation in the presence of sulfur compounds have been investigated. The hydrogenation activity of phenanthrene (PHE) on single noble metal and double noble metal catalysts—Pt/Al 2. 3, Pd/Al 2. 3 and Pd Pt/Al 2. 3 in the presence of dibenzothiophene (DBT) was perforrned in a fixed bed flow reactor. The Pt based catalysts revealed the similar HDS activities and higher HYD activity compared with convertional Mo based ca talysts . The maximum activity was obtained around 32. ℃ for both catalyst types. The Pt based catalysts produced perhydrophenanthrene as a major product at the maximum activity in the hydrogenation of PHE while the Mo based catalysts produced octahydrophenanthrene. A 35 S radioisotope pulse tracer method ( 35 S RPTM) was used to estimate the behavior of sulfur on the working catalysts and to clarity the differences between Pt and Mo based catalysts. Very little amount of labile sulfur was accumulated on the Pt and Pd catalysts in the HDS of [ 35 S]DBT (PtS 0.2. or PdS 0.2. ). This indicates that the mechanism of DBT HDS on noble metal catalysts is significantly different from that on conventional Mo based catalysts where Mo is present as MoS 2.less than 60% of which can be labile in the case of Co Mo/Al 2. 3. Another Ru Cs/Al 2. 3 catalysts were also prepared and the behavior of sulfur on the working catalyst was compared with those of Mo based catalysts and Pt and Pd catalysts. The values of labile sulfur in the HDS reaction for Ru Cs catalysts approximately correspond to RuS 0.5-0.74 . These amounts of labile sulfur are much higher than those for Pt and Pd catalysts. The result suggests that the oxidation state of Ru species is present between the oxidation states of

In recent years, silica nanoparticle aggregates （SNPAs） have been used to decrease the injection pressure of wells in low permeability reservoirs achieving good results. In order to study the mechanisms for reduction in the injection pressure of low permeability wells by the SNPA-diesel oil system injection, the microstructure of SNPAs was observed with a transmission electron microscope （TEM）. The particle size distribution of SNPAs was also measured by the laser scattering method. The viscosities of diesel oil and SNPA-diesel oil system were measured with a capillary viscometer. The effect of SNPAs on the solubility of wax in the diesel oil was experimentally studied. The influencing factors, including temperature and SNPA concentration in diesel oil, on wax solubility were analyzed. A pore-throat film displacement model （PTFDM） was built for mechanism explanation. The microstructure and size distribution analyses show that the SNPAs are in the nanometer size range. The viscosity of the SNPA-diesel oil system is lower than that of the diesel oil. The solubility of wax in the diesel oil increases greatly due to SNPA addition, the solubility ratio reaches 7.5. The solubility of wax in diesel oil increases with increases in the concentration of SNPAs in the diesel oil and with the temperature. It is proved that the addition of SNPAs to diesel oil helps remove the wax deposited near the wellbore. This maybe one of the main mechanisms for injection pressure decreases in low permeability reservoirs.

The kinetics of complex reaction systems were studied on molecular level with the combined method of Monte carlo simulation and Structural Oriented Lumping by focusing on deep catalytic cracking （DCC） process, the model parameters were optimized by means of routine analytic data of a DCC unit. A model was established to transform the feedstock of the complex reaction systems such as DCC to 1000-10000 pseudo-molecules with the Monte carlo simulation and every molecule was expressed by 19 attributes. The results of model simulation showed that these pseudo-molecules reflected the characteristics of feedstock very well and their average properties gave a good agreement with the plant data.

The method for refining the straight-run diesel fuel was studied in laboratory scale in order to make the acid number of diesel fraction comply with the standard while removing the naphthenic acids contained in diesel without causing environmental pollution. After comparing the effect of refining using three solvents, the isopropyl alcohol-HOA was specified as the best solvent. Meanwhile, the relationship between the acid number of diesel fraction and the amount of solvent used and the relationship between the concentration of solvent and temperature and the stability of diesel in terms of its acid number were also investigated. Experimental results had shown that when the mass fraction of the HOA-IPA solvent was 2.% at a dosage of 17 mL of the solvent and a temperature of 30℃, the acid number of the refined diesel fraction was 0.015 mg KOH/g with a good stability of acidity in the diesel fraction.

A Bacillus subtilis strain JA-1 isolated from an oil reservoir was studied. This strain is capable of growth and producing biosurfactant at a temperature of 60 ℃. In nutrient medium it produced biosurfactant which reduced the surface tension from 68.2.mN/m to 2..3 mN/m, with the critical micelle concentration （CMC） of 48 mg/L. The measured surface tension indicated that the biosurfactant possessed stable surface activity at high temperature and a specific range of pH and salt concentrations. The results of thin layer chromatography （TLC） together with FT-IR showed that the metabolic product of strain JA-1 is a lipopeptide biosurfactant. The ability to growth at high temperature and to produce biosurfactant makes strain JA-1 promising for enhanced oil recovery.

MULTI-PEAK MATCH INTENSITY RATIO METHOD OF QUANTI-TATIVE X-RAY DIFFRACTION PHASE ANALYSIS

引用

Acta Metallurgica Sinica(English Letters) 2003年第6期16卷 489-494页

作者： G. Chu, Y.F. Cong and H.J. YouResearch Center of Analysis and Test, Liaoning University of petroleum & Chemical technology, Fushun 113001, China Res. Ctr. of Analysis and Test Liaoning Univ. of Petrochem. Tehnol. Fushun 113001 China

A new method for quantitative phase analysis is proposed by using X-ray diffraction multi-peak match intensity ratio. This method can obtain the multi-peak match intensity ratio among each phase in the mixture sample by using all diffraction peak data in the mixture sample X-ray diffraction spectrum and combining the relative intensity distribution data of each phase standard peak in JCPDS card to carry on the least square method regression analysis. It is benefit to improve the precision of quantitative phase analysis that the given single line ratio which is usually adopted is taken the place of the multi-peak match intensity ratio and is used in X-ray diffraction quantitative phase analysis of the mixture sample. By analyzing four-group mixture sample, adopting multi-peak match intensity ratio and X-ray diffraction quantitative phase analysis principle of combining the adiabatic and matrix flushing method, it is tested that the experimental results are identical with theory.

An innovative idea was proposed to prepare the overbased nano-sized calcium carbonate-calcium petroleum sulfonate in-situ the HIGEE reactor. The test sample prepared by this technology could meet the requirement of the industry standard SH0042.91 for the first-grade product on a par with similar overseas product. The test results obtained upon observation under microscope after freezing etching of specimen revealed that the crystal size of colloidal calcium sulfonate was in the range of 10-30 nm with an average size of 2. nm. The size of the detergent additive was uniform with good transmittance and fluidity. The HIGEE technology possesses five specific features as shown below: Firstly, the carbonation reaction is completed in one step with the reaction time reduced by more than 50% as compared to traditional batch reactor process along with enhanced reaction efficiency, good operability of the process and stabilized product quality. Secondly, ammonia emitted from the reaction is used as the co- promoter without the need for adding ammonia and water as promoters to simplify the promoter system along with effective and strong coupling of reactions. Thirdly, the utilization rate of ca(OH)2.and CO2.is increased by 15% and 30%, respectively, with product yield increased by 15%, and calcium residue decreased by 65%. Fourthly, the HIGEE technology is environmental benign because of gasoline is used in this technology instead of toxic toluene and xylene. Fifthly, the dimension of HIGEE reactor is reduced by above two-thirds. The success in development of this new technology will offer new ideas and technology platform for the synthesis of metal detergent additive to lubricating oils in China.
