| Abstract Scope |
Alumochloride technology can be used to obtain high value-added products from natural or industrial raw materials. Such products include, for example, pseudoboehmite used for refining catalysts. Pilot samples have been successfully tested for distillate hydrotreating to produce Euro-5 compliant diesel fuel (< 10 ppm residual sulfur). One more product is polyaluminum chloride that is used as a coagulant for potable water conditioning and effluent treatment. The said process complies with international standards and allows varying Cl/Al ratio within the range of 1.2-2.4 thus enabling to select the coagulant for different water type. Moreover, the process of production high purity aluminum (5N) has been developed. This product is used to grow sapphires (for LED, smartphone screens) and to cover separators for Li-ion batteries to improve their thermal stability and power intensity. The proposed processes can be established as individual production set-ups or integrated into alumina production by the alumochloride technology. |
