Fractional condensation process

Abstract

The amount of limonene and other pyrolytic oils within the condensate gases produced during pyrolysis of scrap tire carcasses or polyisoprene rubbers can be increased by fractionally condensing and liquefying the gaseous products in a series of vertical condensers. As the gases are passed through each successive condenser, fractions of the gases having a boiling point between 930 degrees Fahrenheit and 110 degrees Fahrenheit are separated and recovered.

I claim:  
     
         1 . A process for recovering valuable gaseous products from scrap rubber tires or polyisoprene rubbers that have been heated and decomposed in a heated reactor comprising: 
 at least two vertical condensers for condensing a fractional portion of said gaseous product and recovering at least one liquid condensate.    
     
     
         2 . The process of  claim 1  in which the gaseous product is a pyrolytic gas.  
     
     
         3 . The process of  claim 1  in which the liquid condensate is a pyrolytic oil having a boiling point between 930 degrees Fahrenheit and 110 degrees Fahrenheit.  
     
     
         4 . The process of  claim 3  in which the liquid condensate includes but is not limited to limonene.  
     
     
         5 . The process of  claim 1  having at least 4 vertical condensers.  
     
     
         6 . The process of  claim 5  in which the gaseous product is a pyrolytic gas.  
     
     
         7 . The process of  claim 5  in which the liquid condensate is a pyrolytic oil having a boiling point between 930 degrees Fahrenheit and 110 degrees Fahrenheit.  
     
     
         8 . The process of  claim 7  in which the liquid condensate includes but is not limited to limonene.
