Bioleaching of trace elements and rare earth elements from coal fly ash

International Journal of coal Science & Technology 2019年第1期6卷 74-83页

作者： Stephen Park yanna Liang Department of civil and Environmental Engineering Southern Illinois University Carbondale1230 Lincoln Drive CarbondaleIL 62901USA Department of Environmental and Sustainable Engineering State University of New York at Albany1400 Washington Ave Albany NY 12222 USA

coal fly ash originated from coal combustion has high concentrations of metals. If suitable leaching techniques are identified, then coal fly ash could serve as a useful source of valuable minerals including rare earth elements (REEs). In this study, three mic.obial strains, candida bombicola, Phanerochaete chrysosporium and cryptococcus curvatus were tested on their performance of leaching trace elements and REEs from fly ash. Through comparing mineral loss and leaching efficiencies resulting from indirect leaching or use of the culture supernatant, c. bombicola was identified to be the best leading to the highest mineral loss and extracting efficiencies of trace elements and REEs among the three strains. The highest mineral loss observed from using the supernatant of this yeast strain was 59.7%. Among all trace elements, As and Mo had the highest leaching efficiency of 80.9% and 79.5%. respectively. The same leaching test led to 67.7% of Yb and 64.6% of Er dissolved from the ash. This study, thus, demonstrated that bioleaching is feasible for leaching metals out of fly ash. The c. bombicola strain deserves further investigation due to its robust actions on metal leaching.

creep behavior and dislocation mechanism of Ni3Al based single crystal alloy Ic6SX at 760℃

引用

Progress in Natural Science:Materials International 2021年第5期31卷 755-761页

作者： Liwu Jiang yanna cui Meiling Wu Shusuo Li Yafang Han National center for Materials Service Safety University of Science and Technology Beijing NcS Testing Technology co. Ltd. Beijing Institute of Aeronautical Materials Research Institute of Aero-engine Beihang University

The creep behavior and dislocation mechanism of Ni3Al-based single crystal alloys Ic6 SX with crystal orientation[001] which was prepared by seed crystal method under the testing conditions of 760℃/500 MPa,760℃/540 MPa and 760℃/580 MPa were investigated. The experimental results showed that the creep properties,dislocation morphology and mechanism of this alloy were different under different stress conditions. With the stress increasing from 500 MPa to 580 MPa, the creep life decreased from more than 1000 h to 32.64 h. The cubic degree of γ’phase in single crystal alloy decreased obviously and the size of γ’phase increased. The mechanism of dislocation movement also changed with the increasing stress. It was found that after the specimen was tested under the condition of 760℃/500 MPa the dislocation network prevented the movement of dislocations and it was difficult for dislocations to enter the γ’phase from the γ/γ’interface. When the stress was 540 MPa, the dislocations cut into the γ’phase by stacking fault. Furthermore, with the stress increasing to 580 MPa, the dislocation entered the γ’phase in the form of extended dislocation and Lomer-cottrell dislocation.

[目的]硅酸盐搪瓷涂层在冷热循环过程中的失效行为很少受到关注。[方法]采用喷雾造粒与烧结相结合的方式制备了多组分硅酸盐团聚烧结喷涂粉末材料,随后采用大气等离子喷涂技术在12crMoV合金钢表面制备了Sio_(2)-Al_(2)o_(3)-Na_(2)co_(3)-c.o基硅酸盐搪瓷涂层,研究了该涂层的微观组织和在700℃下的水淬热震循环行为。[结果]硅酸盐团聚烧结喷涂粉末材料呈球形,粒径分布在20~60μm之间。等离子喷涂硅酸盐涂层呈明显的堆叠层状铺展沉积,表面较为粗糙,其内部虽然存在一定数量的闭孔,但整体较为致密,除了含有一定数量的非晶相,还有Sio_(2)、Al_(2)Sio_(5)和ca_(2)MgSi_(2)o_(7)晶相。该涂层在700℃水淬热震循环145次后发生部分脆性剥落。[结论]热震循环过程中发生的金属基体氧化、晶相分解,以及冷热交变循环等因素产生的热应力可能是导致涂层失效的原因。
