The Total oil recovery™ from scrap rubber-process is based on the low-temperature (300 - 350 °C vs. typical 700 - 800 °C) thermal decomposition of technical rubber in the presence of an original AltimEco catalyst with original pre-processing. The process of decomposition yields two main products - black oil and high surface area technical carbon.

Diagram - How it works The yield of black oils is as high as 96 to 98 % of the organic constituent of the tire rubber. The organic part of tire rubber varies from 55 to 60 % depending on the brand. The properties of the produced black oil are essentially beneficial as compared to the products of crude oil processing. Particularly, the low kinematic viscosity of this high-quality low-sulphur black oil allows heating in wintertime without complicated and expensive equipment for preheating the oil. The costs of such equipment are typically 12 to 20 % of the total costs of central heating facilities.

Thanks to the used catalyst the black oil product has a specific chemical composition (e.g. a high content of aromatics and olefins) and can be directly applied for deblocking oil wells bridged with paraffin obstructions. Laboratory tests have shown a high effectiveness of our oil product in paraffin deposits removal.

As it follows from performed analyses the oil product recovered from scrap tires by the AltimEco technology is a concentrate of cyclane-aromatic hydrocarbons (up to 60 %) and is a valuable source of jet fuel and aviation gasoline on a cyclane basis.

The content of aromatic hydrocarbons is app. 35 wt. % including a noticeable amount of hybrid paraffin-cyclic and naphten-aromatic structures. This (aromatic) fraction of the product is a valuable raw material for the production of benzene, toluene, naphthalene, polymers, etc.

The rest of the oil product represents heavier lubricating oil fractions. Preliminary tests revealed excellent properties of the latter as lubricants for heavy machinery.

The losses of the process are minimized and consist of water vapors and carbon dioxide. The small amount of light gaseous hydrocarbons formed in the process produce sufficient heat to maintain the operation of the facility when being burnt .

The yield of technical carbon is close to 100 % of its content in tire rubber. The carbon can be re-used in the rubber industry or used as a coloring agent in the lacquer and paintwork industry, as a sorbent in the chemical industry or a deoxidizing agent in ferrous metallurgy.
