Authors: Sun Rong Yue , Li Qing Liang , Li Ying Jie
Published: December 2012

Limestone is modified with acetic acid solution as a CO2sorbent in order to solve the problem that the carbonation conversion of limestone decays sharply with the number of cycles. The results show that the carbonation conversion of modified limestone is much higher than original one, and it still achieves as high as 0.5 after 20 cycles. The mechanism of the carbonation conversion improvement for modified limestone was investigated by means of XRD, SEM and nitrogen adsorption instrument. It indicates that the grain size of CaO from modified limestone is smaller than original one. The acetification restrains the increase of grain size for CaO as the number of cycles increase. Sequentially, the extent of sintering for modified limestone is reduced. The fractal dimension of calcined modified limestone is higher than calcined original one. The inner surface of calcined modified limestone is much rougher and more complicated. The acetification makes limestone produce abundant pores. The surface area and pore volume of calcined modified limestone are far greater than those of calcined original one after the same cycles.

Authors: Zhang Wei Feng , Shao Jian
Published: December 2012

A small hollow-fiber membrane contactor system was used to test the absorption and desorption CO2 using mixed absorption solution of SG/PG and TEA. The results showed that absorption effect of SG was better than PG under low concentrations, but their desorption was the opposite. With the increase of concentration, the absorption effect of SG tended to weak, while the desorption was enhanced. And, PG was contrary. The absorption effect of mixed solution(SG+TEA, PG+TEA) was excellent when adding small amount of TEA. And, the absorption effect of TEA-SG mixed solution was amazing under the low concentration of SG. With the concentration of mixed solution increased, the auxo-action of TEA weakened. Instead, TEA played a active effect on promoting the absorption of TEA+PG mixture with the increasing of concentration. The hybrid experimental results shown that 3mol/L PG+0.1 mol/L TEA mixture absorption solution was best in absorption experiments, and 1mol/L PG+0.2 mol/L TEA mixture absorption solution was best in desorption experiments.

Authors: Wang Lian Yuan , Zhu Hai Yan , Cheng Zhen Xing , Ma Meng Meng , Liang Jing , Zhang Xiao Ping
Published: December 2012

Nanosize oxides with acidic or basic sites could neutralize the droplets of chemical warfare agents. Refined bleaching powder was added to increase the reactivity of the nanosize oxides for degradation of GD(3,3-dimethyl-2-butyl methylphophonofluoridate or Soman) and VX(O-ehtyl S-2-(diisopropylamino)ethyl methyl-phosphonothioate). It was found that all the studied decontaminant powders exhibited room-temperature reactivity for GD and VX droplets which depends on their surface acid–base property. Decontaminant powders with basicity like nanosize MgO have the best activity towards GD and the degradation rate was improved obviously for N-MgO due to the adding of refined bleaching powder. However, surface acidity was very important for neutralizing VX over the decontaminant powders.

To better understand the relationship between micro-structures and coalbed methane(CBM), characterisation methods including microscopic photometer, scanning electron microscopy (SEM), mercury porosimetry, nitrogen adsorption at 77K and methane isothermal adsorption were introduced into investigating the adsorption capability of coal reservoir. The results reveal that the micropores volume has a increasing trend with increased vitrinite reflectance. The most favorable pore type is to have good connectivity, very good micro-pores porosity and good adsorption capability. Statistical analysis shows that endo-microfractures are the main type microfractures of Qinshui basin. Based on the results of coal macerals, coal lithotypes, it is found that the bright coal and telocollinites are favorable for endo-fractures formation. Obviously different from the formation of endo-microfracture, exo-microfracture strongly relates to the coal structure. A good match between the fractures and the pores is needed for a favorable CBM reservoir. Based on the evaluation of pore-fracture system, Yangquan is the second CBM commercial area of Qinshui basin.

The experiment on trademark retrieval is performed to prove that the model proposed model has an excellent performance on retrieving the trademark images and outperforms the previously proposed algorithm.

The North area of Yunnan Province is one of favorable target areas for prospecting shale gas of marine hydrocarbon reservoirs in South China, with the black rock series developed well at Lower Cambrian Niutitang Formation and Lower Silurain Longmaxi Formation. The black rock series can be classified into seven types of lithofacies，including black shale，siliceous shale， calcarleous shale，silty shale，carbonaceous shale，argillaceous siltstoue and carbonatite. The total content of organic carbon is 0.02% to 9.37%.The organic matter is overmature，with 2.05%～3.62% of Ro and dominated by type II-kerogen. The microporosity is dominated by the micropores，with pore size less than 10nm, secondly is foraminules with pore size ranging from 10nm to 100nm. The shale gas content is low overall，only 0.42 stere per ton average，and variety range is relatively large. Our research shows the content of plagioclase, carbonate and clay inflect the content of shale gas in the area of relieved synclines and less fault.

Authors: Hua Yan Qiu
Published: December 2012

Visual concept detection is a functional way to detect, manage and classify visual information. No matter it is image retrieval or video retrieval, the system can distinguish object and scene concepts by learning image descriptions itself. However, when the viewing conditions is different or the viewing points is changed, all these will lead to a various result of the image description which collect by the system. So an effective visual concept classification methods should be invariant to different and accidental recording circumstances or conditions. This paper has analysis and summarize the current research status and detection methods of Visual concept detection technologies. Including such methods: salient point detection; social tagged images as a training resource for automated concept detection; extracting distinctive invariant features from images; cross-domain kernel learning method for visual concept detection, etc. And in the end, this paper seeks to unravel the effective when using MIR Flickr in visual concept detection. After comparasion, we want to find the advantages and disadvantages of these typical methods, and hope to give a valuable reference to the following researchers who is interested in visual concept detection and classifications.

Published: December 2012

It is a direction to study for the porosity evolution characteristics of clastic formation from qualitative analysis to quantitative research. To master the porosity evolution rule of sandstones during geologic processes could help to deepen knowledging about the hydrocarbon accumulation mechanism. This paper takes the Member-8 sandstones, Yanchang Formation in Zhenjing Area of Ordos Basin as the research object, and has analysised the current porosity evolution charactersitcs.The sandstone porosity evolution can be divided to a continuous decreased-porosity model mainly due to the mechanical compaction and cementation and a regional enhanced-porosity model mainly due to the dissolution. The superposition of those two types of processes constitutes the entire porosity evolution. Meanwhile,porosity-reduced effects is persist during the whole evolution stage, and porosity-enhanced effects is selective while the organic acids massively dissolves the minerals at the right temperature and depth.

Mine water accident due to the mining above confined water is one of the main factors which affects and threatens safety in the coal production, especially for deep mine. Finding out the mine hydrogeological conditions, deepening the research of water inrush mechanism, and taking the effective safety measures of water bursting prevention, are all the key issues of mining under water pressure safely. Based on fractured rock mass equivalent continuum theory, according to drilling imaging method and water pressure test in borehole, in this paper we focus on discussing the water inrush of the floor rock , determining the floor rock permeability tensor with correction method and simulating the floor inrush problem by coupling stress field and seepage field theory and using anisotropic seepage model with FLAC3D. The results show that, the depth of destroyed floor in normal area and fractured zone in fault are about 30m and 58m respectively. According to empirical equation and numerical simulation, we get the results that the effective protection layer thicknesses are 82m and 115m respectively, and it has presented dangers in fault fractured zone based on the water bursting coefficient method.
