Abstract
An embodiment provides a method for recycling tires, including: injecting, using a pump, a rubber material into a dissociating system, wherein the pump exerts a mechanical force upon the rubber material to reduce a size of the rubber material; within the dissociating system, creating a rubber material mixture, by: injecting a supercritical fluid to be mixed with the rubber material; heating, using a heat source, the rubber material mixture; and atomizing the rubber material mixture; and sending the resulting atomized rubber material mixture to a separating system to separate the rubber material mixture into different components. Other aspects are described and claimed.

A method for recycling tires, comprising:
- injecting, using a pump, a rubber material into a dissociating system, wherein the pump exerts a mechanical force upon the rubber material to reduce a size of the rubber material;
- within the dissociating system, creating a rubber material mixture, by:
- injecting a first supercritical fluid to be mixed with the rubber material in a chamber upstream of an orifice;
- heating, using a heat source, the rubber material mixture;
- atomizing the rubber material mixture;
- injecting a second supercritical fluid in an atomization chamber downstream of the orifice;
- and
- sending the resulting atomized rubber material mixture to a separating system to separate the rubber material mixture into different components.
An apparatus for recycling tires, comprising:
- a pump that injects a rubber material into a dissociating system, wherein the pump exerts a mechanical force upon the rubber material to reduce a size of the rubber material;
- the dissociating system that creates a rubber material mixture by:
- injecting a first supercritical fluid to be mixed with the rubber in a chamber upstream of an orifice;
- heating, using a heat source, the rubber material mixture;
- atomizing the rubber material mixture;
- injecting a second supercritical fluid in an atomization chamber downstream of the orifice;
- and
- a separating system that separates the atomized rubber material mixture into different components from the rubber material mixture.
A product for recycling tires, comprising:
- a pump that injects a rubber material into a dissociating system, wherein the pump exerts a mechanical force upon the rubber material to reduce a size of the rubber material, wherein the rubber material comprises rubber extracted from tires;
- the dissociating system that creates a rubber material mixture, wherein the dissociating system comprises:
- an injector that injects a first supercritical fluid to be mixed with the rubber material in a chamber upstream of an orifice;
- a heat source that heats the rubber material mixture;
- an atomization chamber that atomizes the rubber material mixture;
- a second injector that injects a second supercritical fluid in an atomization chamber downstream of the orifice;
- and
- a separating system that separates the atomized rubber material mixture into different components from the rubber material mixture.
