it is expected that residential units may replace traditional heat and power production systems with cogeneration ones. among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. in this paper, a cogeneration system based on solid oxide fuel cells is examined. the system, including the f...
fuel oil used in power plants contain metal impurities like vanadium. after combustion, this metal remains in boiler fuel ash in the form of oxide. in this research, extraction of vanadium oxide from fuel ash has been investigated. two processes were used for this purpose. a pyro- hydrometallurgy and a hydrometallurgy process. in the pyro-hydrometallurgy process, using sodium carbonate, salt ro...
The solvothermal reaction of thorium nitrate and tris-(4-carboxylphenyl)phosphine oxide in DMF affords a centrosymmetric porous thorium organic framework compound [Th(TPO)(OH)(H2O)]·8H2O (1). In contrast, the ionothermal reaction of the same reagents in the ionic liquid 1-butyl-2,3-dimethylimidazolium chloride results in the formation of a rare example of a chiral and porous thorium organic fra...
As applications for extreme ultraviolet (EUV) radiation have been identified, the demand for better optics has also increased. Thorium and thorium oxide thin films (19 to 61 nm thick) were RF-sputtered and characterized using atomic force microscopy (AFM), spectroscopic ellipsometry, low-angle x-ray diffraction (LAXRD), x-ray photoelectron spectroscopy (XPS), and x-ray absorption near edge stru...
The research about the calculation of burn-up model hexagonal assembly in SCWR reactor using thorium as fuel materials has been done. This uses thorium-232 and uranium-233 materials. Calculations were performed ASMBURN code SRAC program, by determining enrichment, cell radius, analyzing atomic density after burn up, increasing up level, change linear heat. results obtained show value efficient ...
