Abstract ( 647 )
With the increasingly stringent exhaust emission standard and the mature application of exhaust treatment technics, fuel evaporation has become the main source of vehicle emission. Canister containing formed active carbon is the key part of automotive fuel evaporator to reduce emission and reuse fuel vapor significantly. Formed active carbon needs to have a large surface area and large effective pore volume (pore size of 2~5 nm) for high working capacity, high structural strength, fast adsorption and desorption of fuel, which are typically obtained by chemical and physical-chemical activation methods. Chemical and physical methods are common in preparation of activate carbon, chemical activation may produce pollution, which leads to environment problems, although to develop a preferable structure of pore, the physical activation costs a large amount of energy and investment, and the pore structure by this method is relatively poor. Chemi-physical methods can combine the benefits of both physical and chemical activations to decrease the pollution and produce high quality activate carbon. Activation and formation are the main processes for preparation of formed activate carbon; the precursor can change into activate carbon through the activation, and then have the solid shape and structural strength after formation. The integration of formation and activation is the development trend of preparation of formed activated carbon. The performance, characterization, preparation and related mechanisms, and the application in VOCs removal of formed active carbon are reviewed.

Cytotoxic activity of secondary metabolites from co-culture of Eurotium cristatum with Staphylococcus aureus

YANG Juanjuan, ZOU Xianwei, HUANG Yun, LI Qian, CHEN Benke, TANG Jintian
Science & Technology Review. 2016, 34 (9): 96-101. ;  doi: 10.3981/j.issn.1000-7857.2016.09.012
Full text: HTML (1 KB)  PDF  (598 KB)  ( 171 )
Abstract ( 610 )
To evaluate the cytotoxic activity of secondary metabolites from co-culture of Eurotium cristatum with Staphylococcus aureus, seven known compounds, including echinulin(1), cristatumin F(2), neoechinulin A(3), preechinulin (4), flvoglaucin (5), tetrahydroauroglaucine (6), and epiheveadride (7) are isolated from the solid culture of the co-culture of Eurotiumcristatum with Staphylococcus aureus. The structures are checked on the basis of spectroscopic analysis NMR experiments and by mass spectrometric measurements. These metabolites are evaluated in vitro for cytotoxicity activities against four tumor cell lines such as A549, MCF-7, Bel-7402, and Colo205. Compounds 3, 5 and 7 are found to show moderate cytotoxicity against the Bel-7402 cancer cell line.

Coal mine safety training system based on virtual reality and collaborative work technology

Abstract ( 523 )
In order to improve the safety management level of coal mine enterprises and for the safety training of employees, a coal mine safety training system based on virtual reality and cooperative work technology is built. Firstly, the virtual reality technology and the computer supported collaborative work technology are analyzed. Secondly, a technology integration is adopted based on the request of safety training. Then, the structure of the training system is designed, the virtual training scene of the coal mine is constructed, and the expert knowledge base of the safety training is established. Finally, the system is incorporated in the network environment. The feedback shows that the system is attractive and can brought into play the initiative of all the staff and workers. The training result is better by using the cooperative work in the virtual environment than by the traditional teaching in the classes.

Science & Technology Review. 2016, 34 (9): 108-113. ;  doi: 10.3981/j.issn.1000-7857.2016.09.014

Abstract ( 402 )
To apply the radial drilling technique to thermal recovery and development of thin heavy oil reservoirs, a simulation study based on the equivalent continuum principle and local grid refinement technology is carried out. On the basis of historic matching of a higher fitting precision, the influences of the factors of length, plane angle and the quantity of the radial hole on oil production are studied. The results indicate the followings. The radial holes can increase the scope of steam and the area of pressure release and can enhance the production effectively; the oil production gradually increases with the increase of the radial hole length, but the increase rate decreases, with the optimal range of length of the radial hole being 100 to 120 m; a large angle of the distribution of the radial holes in the same plane in the reservoir has weak interference and production grows well; when the number of the radial holes in the same plane increases and the angle between the radial holes gradually decreases, mutual interference gradually strengthens and the output growth gradually declines; and the average angle distribution of four radial holes can obtain an obvious effect on oil production.

Influence of alkaline diagenesis on low resistance oil layer: A case study for Chang 6 Formatin in southern Zhoujiawan in Ordos Basin

Science & Technology Review. 2016, 34 (9): 114-120. ;  doi: 10.3981/j.issn.1000-7857.2016.09.015

Abstract ( 490 )
Based on the data of the cast thin sections, the mercury injection, the well testing and the production test data, this paper systematically analyzes the alkaline diagenetic types and its influences on the low resistivity oil layer in Chang 6 Formation of southern Zhoujiawan. Results show that the three main types of alkaline diageneses in this area are the chlorite cementation, the calcite cementation and the rock salt crystal. Because of a strong compaction resistance of the chlorite film, a large section of conduction system is formed, and the water retention is caused by the adsorption of the chlorite film, the calcite cementation results in a bound water content rising, the rock salt crystal contributes to the formation of the calcite dissolution pore, therefore, the reservoir resistivity is decreased in the studied area. The research result provides some guidance for the analysis of the low resistivity reservoir formation, and a basis for the study of the low resistance reservoir distribution and development.
