Process and system for decomposition of carbon containing waste and process and system for recycling carbon containing waste

Abstract

A system for recycling carbon-containing material is provided. The system includes a reactor for heating the carbon-containing material to produce carbon-containing gases. The system further includes a condenser operably connected to the reactor for condensing a portion of the carbon-containing gases to provide condensed gas and non-condensed gas. The system further includes a conduit arrangement operably connected to the reactor and the condenser wherein the non-condensed gas from the condenser is returned to the reactor.

What is claimed is: 
     
         1 . A system for recycling carbon-containing material comprising:
 a reactor for heating the carbon-containing material to produce carbon-containing gases;   a condenser operably connected to the reactor for condensing a portion of the carbon-containing gases to provide condensed gas and non-condensed gas; and   a conduit arrangement operably connected to the reactor and the condenser wherein the non-condensed gas from the condenser is returned to the reactor.   
     
     
         2 . The system of  claim 1 , further comprising a purification system operably connected to the reactor and the condenser wherein the carbon-containing gas enters the purification system after the reactor and before the condenser. 
     
     
         3 . The system of  claim 1 , further comprising a grinder operably connected to the reactor. 
     
     
         4 . The system of  claim 1 , wherein the carbon-containing material comprises shredded vehicle tires with dimensions not exceeding 200×200 mm. 
     
     
         5 . The system of  claim 1 , wherein the reactor is a two-stage reactor or multi-stage reactor. 
     
     
         6 . The system of  claim 1 , wherein the temperature of the reactor is from about 465 to about 585 degrees Celsius. 
     
     
         7 . The system of  claim 1 , further comprising a gas electric generator wherein a portion of the non-condensed gases may be used to power a gas electric generator. 
     
     
         8 . The system of  claim 1 , wherein the condensed gas is offloaded from the system and used as heating fuel. 
     
     
         9 . The system of  claim 1 , wherein the non-condensed gas is coolant added to the reactor. 
     
     
         10 . The system of  claim 1 , wherein the operation of the reactor is continuous. 
     
     
         11 . A method for recycling carbon-containing material comprising the steps of:
 preheating carbon-containing material;   charging pre-heated carbon-containing material to a reactor;   heating carbon-containing material in the reactor to form carbon-containing gases;   condensing a portion of the carbon-containing gases to form condensed gas and non-condensed gas; and   introducing the non-condensed gas to reactor as coolant.   
     
     
         12 . The method of  claim 11 , wherein the preheating step occurs from about 250 to about 465 degrees Celsius. 
     
     
         13 . The method of  claim 11 , wherein the heating step occurs from about 465 to about 585 degrees Celsius. 
     
     
         14 . The method of  claim 11 , further comprising the step grinding the carbon-containing material prior to the charging step. 
     
     
         15 . The method of  claim 11 , further comprising the step of purifying the carbon-containing gas prior to the condensing step. 
     
     
         16 . The method of  claim 11 , further comprising the step of offloading the condensed gas to be used as heating fuel.
