The Interaction of NH4HSO4 with Vanadium–Titanium

With the wide application of selective catalytic reduction (SCR) systems in power plants for the control of NOx emission in China, a serious problem of catalyst deactivation due to the channel blockage by NH4HSO4 has drawn extensive attention. In this work, a combined experimental and simulation method was utilized to study the interaction between NH4HSO4 and a vanadium–titanium-based

2019/5/22The reduction process of chromium-bearing vanadium–titanium sinter (CVTS) was studied under the simulated conditions of a blast furnace at 1173nbsp;K, and the kinetics and mineral phases were analyzed. The reduction kinetics of CVTS at different reduction times was studied using a shrinking unreacted core model. The microstructure, mineral phase and variations of the sinter during reduction

Abstract The phase composition of the vanadium-containing titanium slags that form upon the reduction smelting of the titanomagnetite concentrate from the Kuranakhsk deposit with an added CaCO 3 flux is studied by optical microscopy, X-ray diffraction, and scanning electron microscopy.

Contaminants remain in titanium metal from incomplete purification in the reduction process or are absorbed in the melting practices employed. Iron in small qualities, 0.5 to 1%, appears to have a contaminating effect on ductility, but in larger quantities acts to influence the ductility no worse than other good substitutional alloying elements.

Beginning of the reaction, V ( vanadium oxide reduction rate of 28.75% -38.34 %) mainly occur in small pieces granular and long strips of titanium - containing material phase titanium closely associated with the conduct of the reduction reaction, V is gradually

Moreover, the low-temperature reduction pulverability rate of the vanadium-titanium sintered ore RDI −3.15 is significantly higher than that of ordinary sintered ore [3–7]. Oxygen-enriched sintering refers to the addition of a certain amount of oxygen in the intake of air during sintering to facilitate the sufficient burning of the sintering fuel and sintering process of the reaction.

Home News King River makes inroads into vanadium capex reduction Date: Jan 21, 2019 King River Resources says that initial positive metallurgical testing results from its heated acid vat leaching test work on ores from its Speewah project support the development of an alternative processing route that could drastically lower capital and operating costs at the giant vanadium project.

THERMODYNAMIC PROPERTIES OF ALUMINUM

A second series of binary niobium alloys containing titanium and vanadium, and of ternary and quaternary alloys containing chromium, molybdenum, titanium, andmore Comparison of the corrosion behavior of cold-worked and annealed alloys indicated that cold work (90 per cent reduction in thickness) increases the corrosion resistance of niobium alloys.

Reduction Behaviors of Iron, Vanadium and Titanium Oxides Apr 27, 2017 The results demonstrate that the recovery ratios of both iron and vanadium increase as the binary basicity increases from 09 to 12, whereas the reduction of titanium oxides is mitigated when the basicity is maintained at 11 Compared to its weak effect on the recovery ratio of iron, increasing MgO content improves the

It can be found from Table 1 that vanadium-titanium sinter has more gangue minerals than traditional sinter, but the FeO content in the two sinters is similar. From Table 2, it can be observed that the vanadium-titanium sinter has a lower reduction index (RI), less tumbler index (TI), and greater reduction degradation index (RDI-3.15) compared to the traditional sinter, which indicates that
