The United Nations General Assembly declared 2012 the International Year of Sustainable Energy for All.

United Nations Secretary-General Ban Ki-moon called for a "a global clean energy revolution – a revolution that makes energy available and affordable for all”, adding that this was essential for minimizing climate risks, reducing poverty, improving global health and meeting the Millennium Development Goals, for global economic growth, peace and security, and the health of the planet.

Boehmite & hydrogen production

One of significant directions R&D research of our company - is the search of new methods for a low cost and energy-efficient production of nanopowders as well as widening the scope of their application for solving ecological problems. In this direction we achieved significant success developing the revolutionary SCHTO technology for environmentally safe, energy-efficient & law cost method of nanocrystalline hydroxide (boehmite) and hydrogen production.

The unique technology is based on the process of supercritical hydrothermal oxidation of aluminum powder. The technology is capable to produce on an industrial scale fully crystallized, nanocrystalline aluminum hydroxide (boehmite) of high chemical purity and dispersibility and high purity hydrogen, which quality meets high EU standards, and which is considered as one of the main future fuels, and an essential raw material in many important industries (refineries, petrochemicals, fertilisers, food, etc.).

The basic idea is to use aluminum as a raw material for production of nanocrystalline aluminum hydroxide, and an intermediate energy source for hydrogen and energy production during the hydrothermal oxidation of aluminum.

Our technology of supercritical hydrothermal oxidation of aluminum powder is of potential interest to any company related to the production of valuable boehmite nanopowders and hydrogen, energy production and environment areas.

Boehmite is a nanopowder made through the reaction  of supercritical hydrothermal oxidation of aluminum powder. It is a relatively new material traditionally used in a wide range of applications: production of water filters, binder for catalysis, refractory materials, sol-gel ceramics, rheology control, surface frictionising and paint detackification. Other uses for boehmite nanopowders include surface coating as well as polymer additives.

Boehmite is traditionally used in applications such as sol-gel ceramics, binder for catalysis, refractory materials, rheology control, surface frictionising and paint detackification. Other uses for boehmite alumina powders include surface coating as well as polymer additives.

SCHTO technology allows to obtain materials of a high purity (up to 99.99% of weight content of the main component).

Economic efficiency: key facts about SCHTO installations for boehmite production:

  • Produces up to 2 kg of boehmite nanopowder from 1 kg of parent aluminum powder;
  • Commercial price of boehmite is €30-300/per kg, depending on the quality of the powder, although the value of parent aluminum is €2-3/kg;

  • Huge amount of cheap Hydrogen is produced during boehmite production process as by-product;

  • SCHTO process of boehmite production takes place with emanation of huge ammounts of heat, which is sufficient not only for supplying the plant itself but it also can transfer some energy to external customers.


Boehmite for whater treatment.

Produced by unique SCHTO technology Boehmite nanopowder can be used for production of Boehmite nanofibers (AlOOH).

The main application of Boehmite nanofibers is water filters. Made from these nanofibers water filters are strongly effective in removing of microorganism such as Bactria, viruses and etc by 99.9999%.

Meanwhile, they are also effective in removing of a great variety of pollutants including heavy metals, microorganisms, organic materials, colloidal particles with any sizes, unpleasant odor and taste of water, temporary hardness and etc.

The application of ultradispersed fibers (UDF) of BOEHMITE FOR PURIFICATION OF DRINKING AND TECHNOLOGICAL WATER IS VERY EFFICIENT!

Such UDF can be used to capture precious metals in flushing water to reduce their losses in the technological process. The fact that nanopowders can be granulated increases their technological value.

A layer of oxides with a thickness of some centimeters can purify big volumes of water from admixtures of metals and fluorine, the initial concentration of which can be tens mg/l, with an efficiency close to 100%.

waterconsumption.pngA big specific surface of nanocrystal boehmite provides an efficient purification of drinking and technological water from nonorganic and organic substances. Nanosize boehmite fibers are able to adsorb pathogenic microorganisms, viruses, and toxins.

Application of nanocrystal boehmite (A1OOH) for adsorption of toxic and harmful substances from filtrates can be advantageous in comparison to carbon because the subsequent elimination of organic substances adsorbed with boehmite by the developed SCHTO technology allows, as distinct from carbon, to save the adsorbent
