Abstract:
A process for treating waste rubber comprising in series the steps of:heating a quantity of rubber in an atmosphere having less than 6% oxygen gas content at a temperature between 340 Celsius and 510 degrees Celsius and a negative pressure such that said rubber is vaporized and defines a vaporized rubber, said vaporized rubber having a plurality of hydrocarbon constituents therein; said heating being performed by radiant means; spraying said vaporized rubber with an oil having a boiling temperature greater than 175 degrees Celsius by a venturi separator, such that said oil binds to heavy oil in said hydrocarbon constituents; condensing a remaining portion of the vaporized rubber such that light oils in said hydrocarbon constituents liquefy and are separated from non-condensing hydrocarbon gases.
