| 3 | Effect of impregnation methods on sorbents made from lignite for desulfurization at middle temperature显示文摘With lignite after vacuum drying as the raw material,a series of Zn-based sorbents were prepared by static impregnation,ultrasonic-assisted impregnation,bubbling-assisted impregnation and high-pressure impregnation.The physical properties and the desulfurization performances of Zn-based sorbents were studied systematically by XRD,BET,AAS characterization techniques and the fixed-bed desulfurization evaluation apparatus.The sorbents obtained by high-pressure impregnation method have a larger specific surface area,pore volume and pore diameter comparing with other methods,which is conducive to the sulfidation reaction of hydrogen sulfide gas in the sorbent.The effects of pressure during the high-pressure impregnation and concentration of Zn(NO3)2 precursor solution on the sorbents properties and desulfurization behavior were investigated.The higher the impregnation pressure and the concentration of impregnation solution are,the greater the amount of the active components are uploaded.However,overhigh impregnation pressure can cause collapse and blocking of the carrier pore.The optimal operating condition of high-pressure impregnation method for preparing the sorbents was the impregnation pressure of 20 atm and the solution concentration of 41%.Under that condition,the sorbent had the best desulfurization ability with a sulfur capacity of 13.94 gS/100 gsorbent and a breakthrough time of 54 h.Its desulfurization precision and efficiency of removing H2S before sorbent breakthrough from the middle temperature gases of 400℃ can reach<5 ppm and>99%,respectively.Sorbents could be regenerated under the condition of 1 vol%O2,20 vol% H2O,0.5 vol% NH3,and N2balance gas.The regenerated sorbent could be used for repeated absorption of H2S with a slight decrease in desulfurization effect. | Yurong Dong Xiurong Ren Meijun Wang Qiang He Liping Chang Weiren Bao | 2013 | Journal of Energy Chemistry2013，22，5： | 3 |

| 8 | Desulfurization performance of iron-manganese-based sorbent for hot coal gas显示文摘A series of iron-manganese-based sorbents were prepared by co-precipitation and physical mixing method,and used for H_(2)S removal from hot coal gas.The sulfidation tests were carried out in a fixed-bed reactor with space velocity of 2000 h^(-1)(STP).The results show that the suitable addition of manganese oxide in iron-based sorbent can decrease H_(2)S and COS concentration in exit before breakthrough due to its simultaneous reaction capability with H_(2)S and COS.Fe3O4 and MnO are the initial active components in iron-manganese-based sorbent,and FeO and Fe are active components formed by reduction during sulfidation.The crystal phases of iron affect obviously their desulfurization capacity.The reducibility of sorbent changes with the content of MnO in sorbent.S7F3M and S3F7M have bigger sulfur capacities(32.68 and 32.30 gS/100 g total active component),while S5F5M has smaller sulfur capacity(21.92 gS/100 g total active component).S7F3M sorbent has stable sulfidation performance in three sulfidation-regeneration cycles and no apparent structure degradation.The sulfidation performance of ironmanganese-based sorbent is also related with its specific surface area and pore volume. | Xiurong REN Weiren BAO Fan LI Liping CHANG Kechang XIE | 2010 | Frontiers of Chemical Science and Engineering2010，4，4： | 1 |

| 11 | Industry Distribution Characteristics of Benzene-ExposedWorkers with Cytopenia - Four Provinces, China, 2020显示文摘What is already known about this topic?Benzene is harmful to the hematopoietic system and can cause leukemia.However,benzene is still being used in various industries including furniture,rubber,plastic products,and metal product manufacturing.What is added by this report?The white blood cell count of workers in general equipment,special equipment,chemical raw materials,and chemical products manufacturing decreased significantly.The enterprises in which benzene concentration exceeded the occupational exposure limit were small enterprises and private enterprises.What are the implications for public health practice?Regular health examinations are necessary for benzeneexposed workers.In addition,the monitoring of benzene concentration in small enterprises and private enterprises should be strengthened. | Dongning Hua Xue Wang Lei Han Jin Zhou Xiurong Cheng Boshen Wang Juan Zhang Jinzhe Li Peiyu Xu Shang Gao Lifang Zhou Fei Li Xinglin Fang Jin Li Zihuan Wang Jing Liu Jie Ren Baoli Zhu Meibian Zhang Caihong Xing | 2022 | China CDC weekly2022，4，51： | 0 |
