Benefits of technology

[0007]The technology described here provides a combination of a concept totally new to the concept of extraction of value from oils derived from pyrolysis of scrap while preserving the valuable carbon black solids. This combination yields high concentrations of highly valued fragrance and essential oils that are known for their unique solvent properties, thei

Abstract

A device and process for the vacuum pyrolization of scrap tires to produce a pyrolytic oil from which valuable terpenes such as limonene and pulegone may be extracted and purified.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Not applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]Not Applicable.BACKGROUND OF THE INVENTION[0003]The continuing accumulation of used tires is one of the worst solid waste problems facing industrialized countries. It is estimated that North America discards approximately one used tire per person per year. The incineration of tires is both costly and complex, while stockpiling used tires is the subject of growing concern. Moreover, the possibility of tire fires on these sites poses an ever-increasing threat to the environment. On the other hand, tires represent a source of energy and chemicals. By thermal decomposition, it is possible to recover useful products in an environmental friendly way.[0004]The presence of terpenes in “Py-oil” or rubber pyrolysis oil has been known for decades. However, the concentration is low. Attempts to separate the terpenes via distillation have been counterproductive because the heat requi...
