Pyrolyzed rubber products and processes

1. A pyrolysis process, comprising the steps of;

depositing a quantity of waste into a porous container, the porous container adapted to allow at least one convective stream of substantially anaerobic gas to flow therethrough;

inserting the porous container into a pyrolysis thermal processor;

sealing the thermal processor;

circulating the at least one convective stream of gas in the pyrolysis thermal processor;

heating the waste with the convective stream of gas according to a predetermined time-temperature profile to pyrolyze the waste and form a carbonaceous char, wherein the time-temperature profile includes ramping, a temperature of the thermal processor from an initial temperature to a first temperature over a period of about 40 to 60 minutes, wherein the initial temperature is one of ambient temperature and a temperature to which the thermal processor was cooled following a previous pyrolysis cycle, wherein the first temperature is from about 550° F. to about 650° F., holding the temperature of the thermal processor at the first temperature for a first soak period of about 5 to about 15 minutes to evolve quantities of product oils and product gases from the waste, ramping the temperature of the thermal processor to a second temperature over a period of about 90 to 120 minutes, wherein the second temperature is from about 770° F. to about 870° F., holding the temperature of the thermal processor at the second temperature for a second soak period of about 30 to about 60 minutes to pyrolyze the waste and form the carbonaceous char, the second temperature adapted to minimize a graphitization of the carbonaceous char, and cooling the thermal processor to a third temperature by circulating the at least one convective stream through the thermal processor and the cooler, wherein the third temperature is between about 120° F. and about 160° F., wherein the pyrolysis process is performed under substantially atmospheric pressure;

cooling the carbonaceous char by circulating the at least one convective stream of gas through a cooler; and

collecting at least one of a carbon black product, an oil product, a gaseous hydrocarbon product, and a recyclable metal product.

providing a quantity of whole tires; and

shredding the whole tires to form the quantity of waste to be deposited in the porous container.

3. The pyrolysis process according to claim 1 , further comprising the steps of:

purging the thermal processor with a substantially anaerobic purge gas following the insertion of the porous container therein; and

recirculating a hydrocarbon recovery gas produced during the heating of the waste through the thermal process, wherein the purge gas and the recovery gas form at least a portion of the convective stream of gas.

4. The pyrolysis process according to claim 1 , wherein the step of heating the waste includes the step of heating the at least one convective stream with a gas fired heater to indirectly heat the waste to a temperature sufficient to pyrolyze the waste.
