Entwicklungsaussichten für Vanadium-Titan-Flüssigkeitsstrom-Energiespeicher

Vanadium spielt in den Dekarbonisierungs-Plänen Chinas eine immer größere Rolle. Im Fokus stehen dabei Legierungen für die Flugzeugindustrie sowie Vanadium-Redox Flow Batterien als Energiespeicher. Beide Trends treiben die Nachfrage des begehrten Rohstoffs an und eröffnen Chancen für Unternehmen.

How to recover vanadium from vanadium titanium-magnetite (VTM) ore?

Recovering vanadium from vanadium titanium-magnetite (VTM) ore using (NH 4) 2 C 2 O 4 is a clean hydrometallurgical process, but the drawback is the low recovery and slow kinetics due to the formation of inhibitor.

What is a vanadium titanium based catalyst?

Vanadium-titanium-based catalysts are the most widely used industrial materials for NO x removal from coal-fired power plants.

Are vanadium flow batteries the future of energy storage?

Vanadium flow batteries are expected to accelerate rapidly in the coming years, especially as renewable energy generation reaches 60-70% of the power system's market share. Long-term energy storage systems will become the most cost-effective flexible solution. Renewable Energy Growth and Storage Needs

Where does vanadium titano-magnetite come from?

Vanadium titano-magnetite (VTM) provides 88% of the world’s vanadium [7, 8]. Of these, 14% comes directly from VTM, and 74% comes from vanadium slag produced during steelmaking . The direct extraction of vanadium from VTM adopts a sodium salt roasting water leaching process . It is applied by enterprises in South Africa and Brazil .

Does vanadium undergo metamorphosis?

Over the years, researchers have made use of the inherent ability of vanadium that undergoes metamorphosis between different coordination polyhedra accompanied by transitions in the oxidation state for reversible intercalation/insertion of more than one guest ions without breaking the structure apart.

Does deposited potassium increase Deno X efficiency compared to unmodified vanadium titanium based catalysts?

Yu et al. [ 127] found that the deposited potassium could form V–O–K species, inhibited the aggregation of vanadium oxides, and thus, improved the thermal stability of the catalysts ( Fig. 7 ). Compared to unmodified vanadium-titanium-based catalysts, this species could increase the deNO x efficiency threefold after treatment at 800 °C for 4–5 h.
