Fields of application

Probable use of developed technology in the solar-hydrogen energy, machine profile companies, special steel metallurgy and others where they can accumulate the containing tungsten waste.

Short Description

Developed a complex manufacturing process of thermal processing of industrial waste containing tungsten, which involves obtaining individually hydrogen, hydrogen and tungsten oxides and metallic W or carbide WC using metal-vapor method and heating in the solar furnaces.

Expected properties

According to the research of Japanese scientists, tungsten has a much more reactive to oxidation by water steam and recovery compared to most metals, which have passed the test in the redox cycles of hydrogen, but the limiting factors of its use are the high value and strategic importance of the metal. New technological approaches, the use of waste instead of pure metals and the "sterility" of radiant heating give reason to expect high levels of performance and quality of hydrogen and of tungsten waste recycling products.

Benefits

The use of tungsten waste and solar energy for heating, the possibility of obtaining individually hydrogen or solid products of thermal processing, including a one-time use of waste can make the complex technology that is offered, economically viable, despite the high value and strategic importance of tungsten.
Scheme of the developed device with the solar heaters for core reactor and steam generator will significantly simplify the design of high-temperature installations, more systematically and economically use energy and materials.

Competitors

Weizmann Institute of Science, Іsrael (CRRF);
Institut de Science des Materiaux CNRS, France.

Stage of elaboration

During this first phase of the project there were developed three flow diagrams and schematic diagrams of the experiments in the solar furnace and thermo-gravimetric analysis, began assembling of technological devices. Thermo chemical analysis of the steam tungsten oxidation processes and oxides reduction in carbon-containing gases was fulfilled. Based on previous experience of the authors of the project the range of primary objects of study was defined.
