| 1 | Evaluation of Four Coals for Blast Furnace Pulverized Coal Injection显示文摘One of the effective methods of reducing coke consumption is pulverized coal injection. The most important problems encountered in this method are reduced permeability,unburned and high ash content. To select the best coal for injection,suitable tests can be used. Therefore,experiments such as proximate and ultimate analysis,Rock-Eval and combustion tests were performed on four kinds of coals from different mines,including Sarakhs,Sangrood,Karmozd,and Tabas. The results of proximate and ultimate analysis indicated that although the sulfur content and ash content of selected coals were a little high,they were suitable for coal injection. The results of combustion experiments and Rock-Eval tests showed that Karmozd coal was the best one to be injected into blast furnace. The result indicated that the mixing of coals could improve the combustion properties of pulverized coals. | Sh Raygan H Abdizadeh A Eskandari Rizi | 2010 | Journal of Iron and Steel Research(International)2010，17，3： | 12 |

| 19 | Effect of chemical activation process on adsorption of As(V) ion from aqueous solution by mechano-thermally synthesized zinc ferrite nanopowder显示文摘Nanostructured ZnFe2O4 was synthesized by the heat treatment of a mechanically activated mixture of ZnO/α-Fe2O3.X-ray diffraction(XRD)and differential thermal analysis(DTA)results demonstrated that,after 5 h of the mechanical activation of the mixture,ZnFe2O4 was formed by heat treatment at 750°C for 2 h.To improve the characteristics of ZnFe2O4 for adsorption applications,the chemical activation process was performed.The 2 h chemical activation with 1 mol·L?1 HNO3 and co-precipitation of 52%?57%dissolved ZnFe2O4 led to an increase in the saturated magnetization from 2.0 to 7.5 emu·g?1 and in the specific surface area from 5 to 198 m2·g?1.In addition,the observed particle size reduction of chemically activated ZnFe2O4 in field emission scanning electron microscopy(FESEM)micrographs was in agreement with the specific surface area increase.These improvements in ZnFe2O4 characteristics considerably affected the adsorption performance of this adsorbent.Adsorption results revealed that mechano-thermally synthesized ZnFe2O4 had the maximum arsenic adsorption of 38%with the adsorption capacity of 0.995 mg·g?1 in a 130 mg·L?1 solution of As(V)after 30 min of agitation.However,chemically activated ZnFe2O4 showed the maximum arsenic adsorption of approximately 99%with the adsorption capacity of 21.460 mg·g?1 under the same conditions.These results showed that the weak adsorption performance of mechano-thermally synthesized ZnFe2O4 was improved by the chemical activation process. | Mohammad Sefidmooy Azar Shahram Raygan Saeed Sheibani | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，4： | 1 |
