3SO_2/Hg removal from flue gas by dry FGD显示文摘To study the mechanism of SO 2 and Hg removal from flue gas, an experimental packed bed reactor was designed to simulate the dry FGD, where a mixture of lime and fly ash in ratio 1:3 w/w was used as the SO 2 and Hg sorbent, and steam at temperature of 100℃ was applied for activation of the sorbent, while the activation time set to 20 min. The experimental factors including the SO 2 /Hg sorbent characteristics, 50% breakthrough time for SO 2 /Hg removal, sorbent packed bed depth and reaction temperature were investigated. The experimental results show that after steam activation, the BET specific surface area and specific pore volume increased from 37.8 to 45.5 m 2 /g and from 0.42 to 0.51 cm 3 /g, respectively. With activation of the sorbent by steam, the 50% breakthrough times of SO 2 and Hg removal increased from 34 to 42 min and from 23 to 45 min, respectively. When the packed bed depth was increased from 5 to 25 mm, the 50% breakthrough times for Hg and SO 2 removal increased from 12 to 52 min and from 6 to 47 min, respectively. With the increase of the reaction temperature, the 50% breakthrough of SO 2/Hg removal decreased accordingly. Steam activation can efficiently improve SO 2 /Hg removal simultaneously.Wang Fan Wang Hongmei Zhang Fan Zhu Jinwei Tian Gang Liu Yu Mao Jixian 2012International Journal of Mining Science and Technology2012,22,1:5
4Natural Gas Types,Distribution Controlling Factors,and Future Exploration in the Western Qaidam Basin显示文摘The Paleogene and Neogene oil and gas in the western Qaidam basin have a regular distribution in three concentric zones from the edge to the center of the basin.Natural gas mainly occurs in the inner zone,and the gas-oil ratio of the northern area of the basin is significantly higher than that of the southern area.Large amounts of carbon isotope data of natural gas,plotted in Xshaped and comprehensive identification diagrams for the southern area and northern area,respectively,were used to identify the types of natural gas.The large-scale distribution of natural gas is highly consistent with the Ro values of major source rocks,but is poorly correlated with the type of organic matter.This indicates that the main controlling factor of natural gas distribution is organic matter maturity,and the kerogen types act as the basis for the formation of different types of natural gas.Paleouplifts and squeezed anticlines near hydrocarbon generation depression centers,which are major natural gas-rich regions,control the migration directions of natural gas,while hydrocarbon migration pathways and fault systems connecting gas sources are the most important factors for natural gas reservoir formation in the inner basin.Therefore,favorable zones for natural gas distribution can be predicted on the basis of the distribution of thermal evolution and the gas generation intensity of major source rocks as well as the structural map.The Shizigou-YoushashanYingdong-Dawusi,Youquanzi –Kaitemilike- Youdunzi,and Xiaoliangshan – Nanyishan- Dafengshan structural belts are favorable zones for natural gas accumulation.This study has important theoretical and practical significance for future natural gas exploration.GUO Zeqing SUN Ping LI Jian ZHANG Lin LIU Weihong TIAN Jixian ZHANG Shaosheng ZENG Xu 2014Acta Geologica Sinica(English Edition)2014,88,4:3
5Simulation of the Flow Conditions in Different Types of Bar Structures of Disc Refiner显示文摘Disc refiner is a critical equipment in the pulping and papermaking industry, pulp is refined in the refining zone, and different bar structures of refining disc constitute the different refining zones. With the use of the 3D modeling software SOLIDWORKS, five different refining discs that are commonly used in low consistency pulping, were built. The five refining discs were simulated and analyzed using the Computational Fluid Dynamics(CFD)software. The distribution of pulp velocity and surface shear stress, which is displayed between the bar and groove structures, can indirectly show the stress conditions on the refining discs. This paper provides a theoretical basis for research on the bar and groove failure of the refining discs.JiXian Dong LuBing Han Huan Liu 2018Paper And Biomaterials2018,3,1:3

9Design Method of Curved-bar Refining Plates for Disc Refiner显示文摘Straight-and curved-bar refining plates are two important types of plates commonly used in disc refiners in the papermaking industry.Theoretically,the curved-bar refining plate has a relatively uniform bar interaction angle,which indicates uniform refining effects.The bar angle of the curved bar was proposed and two typical curved-bar plates,the three-stage radial curved-bar plate and isometric curved-bar plate,were designed in this paper.The arc equations of the curved-bar center line and curved-bar edges were established and finally,the specific edge load(SEL)of the curved-bar plate was derived.The determination of bar parameters was discussed,which provides a theoretical basis for the design of curved-bar plates.Huan Liu JiXian Dong XiYa Guo RuiFan Yang Hui Jing XiaoJun Jiang 2019Paper And Biomaterials2019,4,1:2
10An evidence for the strong association of N-methyl-2-pyrrolidinone with some organic species in three Chinese bituminous coals显示文摘Three Chinese bituminous coals collected from Shenfu, Heidaigou and Feicheng coal fields were re- spectively extracted with carbon-disulfide/N-methyl-2-pyrrolidinone (CS2/NMP) mixed solvent (volume ratio 1:1) at room temperature followed by distillation of CS2 under ambient pressure and subsequent removal of most of NMP by distillation at 110℃ under reduced pressure to afford mixed sol- vent-extractable fractions (MSEFs) with small amount of NMP. Acetone-extractable fraction 1 (AEF1) was obtained by extracting each MSEF under ultrasonic irradiation at room temperature and subse- quently using a Soxhlet extractor. Direct extraction of each bituminous coal affords acetone-soluble fraction 2 (AEF2). GC/MS analysis shows that m/z of base or secondary peak in mass spectra of a se- ries of components from each AEF1 is 98, whereas such components were not detected in AEF2. Since m/z of base peak in mass spectrum of NMP itself is 99, the base or secondary peak at m/z 98 should result from loss of α-H from NMP, i.e., NMP is strongly associated with some organic species (OSs) and thereby the components detected with base or secodary peak at m/z 98 in their mass spectra should be associated NMP-OS.LIU ChanMin ZONG ZhiMin JIA JiXian LIU GuangFeng WEI XianYong 2008Chinese Science Bulletin2008,53,8:2

12sRNAanno-a database repository of uniformly annotated small RNAs in plants显示文摘Small RNAs(sRNAs)are essential regulatory molecules,and there are three major sRNA classes in plants:microRNAs(miRNAs),phased small interfering RNAs(phased siRNAs or phasiRNAs),and heterochromatic siRNAs(hc-siRNAs).Excluding miRNAs,the other two classes are not well annotated or available in public databases for most sequenced plant genomes.We performed a comprehensive sRNA annotation of 143 plant species that have fully sequenced genomes and next-generation sequencing sRNA data publicly available.The results are available via an online repository called sRNAanno(www.plantsRNAs.org).Compared with other public plant sRNA databases,we obtained was much more miRNA annotations,which are more complete and reliable because of the consistent and highly stringent criteria used in our miRNA annotations.sRNAanno also provides free access to genomic information for>22,721 PHAS loci and>22 million hc-siRNA loci annotated from these 143 plant species.Both miRNA and PHAS loci can be easily browsed to view their main features,and a collection of archetypal trans-acting siRNA 3(TAS3)genes were annotated separately for quick access.To facilitate the ease of sRNA annotation,sRNAanno provides free service for sRNA annotations to the community.In summary,the sRNAanno database is a great resource to facilitate genomic and genetic research on plant small RNAs.Chengjie Chen Jiawei Li Junting Feng Bo Liu Lei Feng Xiaoling Yu Guanliang Li Jixian Zhai Blake C.Meyers Rui Xia 2021Horticulture Research2021,8,1:1
13Evaluation of strategy for analyzing mouse liver plasma membrane proteome显示文摘Plasma membrane (PM) proteome is one of the major subproteomes present in the cell,and is very important in liver function. In the present work, C57 mouse liver PM was purified by density-gradient centrifugation. The purified PM was verified by electron microscope analysis and Western blotting. The results showed that the PM was enriched by more than 20-fold and the contamination of mitochondria was reduced by 2-fold compared with the homogenization fraction. Proteins were separated by 2DE and 1DE, trypsin-digested and submitted to ESI-Q-TOF and MALDI-TOF-TOF mass spectrometry or directly digested in solution and analyzed by LC-ESI ion trap mass spectrometry. In all, 547 non-redundant mouse liver PM proteins were identified, of which 34% contributed to plasma membrane or plasma membrane-related proteins. This study optimized and evaluated the HLPP plasma membrane proteome analysis method and made a systematic analysis on PM proteome.CHEN Ping ZHANG LiJun LI XuanWen WANG XiE CAO Rui LIU Zhen XIONG JiXian PENG Xia WEI YingJuan YING XingFeng WANG XianChun LIANG SongPing 2007Science China(Life Sciences)2007,50,6:1
