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.

Super Critical Hydrothermal Oxidation (SCHTO) process.

SUPERCRITICAL CONDITIONS

Under hydrothermal processes we understand those that occur in aqueous medium at high pressure and temperature. A special place is occupied by chemical processes in supercritical aqueous medium (Tcr = 374,2 º C, Pcr = 217.6 atm), as in nature there is a huge chemical supercritical reactor. 

This is subsoil in which water is kept under supercritical conditions (at a depth of more than 50 meters) and where chemical reactions with its participation take place. In recent years, the hydrothermal oxidation of organic and inorganic compounds in near-critical and supercritical aqueous mediums have actively been studied.

At temperature above 374,2 º C and pressure greater than 217.6 atm water transforms into a supercritical state,which is called fluid. Under these conditions, water acquires special properties different from those of the liquid and gaseous phases. It turns from a polar liquid into a nonpolar medium and becomes capable of dissolving hydrophobic compounds. Supercritical water has unlimited thermodynamic compatibility with organic compounds and oxygen, diffusion rate increases, and its oxidizing ability rises dramatically.

According to available estimates in the literature and conducted patent research SCHTO method claims to have the highest environmental and economic efficiency.

When processing aqueous mixtures of organic and inorganic compounds containing toxic substances with supercritical water, at least 99.99% of organic compounds in the mixture are converted into environmentally safe water and carbon dioxide. Nitrogen-containing organic compounds and ammonium substances are decomposed with the release of gaseous nitrogen. Chlorine, fluorine, phosphorus and sulfur in organic substances form acid residues and are easily isolated in the form of inorganic acids or salts. Metals are isolated in the form of inorganic salts or oxides.

Nanostructured oxides and salts of metals of commercial value are generated during recycling process as solid waste.


As the result of a long-term research and development effort and a wide experience utilizing supercritical hydrothermal oxidation processes in order to solve the problem of finding new ways for low-cost clean energy production on an industrial scale, our team has developed the revolutionary technology for environmentally safe, energy-efficient & law- cost method of hydrogen production - installation of supercritical hydrothermal oxidation (SCHTO).

The known nowadays methods of hydrogen production from aluminium treatment are not effective in providing the completeness of oxidation of aluminum with water, or they are underproductive and based on the application of expensive powders of super dispersed aluminum and activated aluminum alloys.

The unique SCHTO technology, based on the process of supercritical hydrothermal oxidation of aluminum powder, is capable to produce on an industrial scale fully crystallized, high purity nanocrystalline aluminum hydroxide (boehmite), oxide (corundum) and hydrogen, which quality meets high EU standards. 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.

For providing aluminum combustion in aqueous medium we suggest to increase diffusion rate at the cost of activation of aluminum powder by the replacement of a strong oxide film by a polymer water-soluble film and usage of water at about- or overcritical parameters of its condition.

The activation of aluminum can be done for example on the technology of advance decomposition of industrial aluminum powders in water-soluble polymer medium. It provides the replacement of an oxide film by a polymer one which protects aluminum surface from air oxidation. When aqueous medium getting to the polymer film, the latter dissolves, and aluminum particles react with water molecule.

The uniqueness of our innovative SCHTO technology is that one developed technological process can be used for environmentally safe, energy-efficient & law cost nanocrystalline hydroxide (boehmite) and hydrogen production, high quality corundum and clean-energy production.

Additional advantages of the proposed technology are:

  • self-sufficiency (the technological process flows with heat, which is enough not only for self-reliance installation of thermal energy, but also for the output of energy to external customers);
  • mobilityis the ability to produce the installation of any capacity and size, depending on the needs of our customers: from small compact mobile installation to the vast scale of the municipal plant.Meaning that we are always available to discuss individual capacity options with customers.
