Abstract:
1. An apparatus for the destructive distillation of rubber to produce hydrocarbon and solid carbonaceous char, comprising: a distillation chamber for holding the rubber, said chamber being sealable for the substantial exclusion of oxygen from said chamber; a heater associated with said distillation chamber for heating rubber in said chamber to a temperature sufficient to pyrolyze the rubber, distill a vapor comprising hydrocarbon from the rubber and produce a solid carbonaceous char; a gas outlet for removing said vapor comprising hydrocarbon from said chamber; a condenser for producing a liquid fraction comprising hydrocarbon from said vapor removed from said chamber; and a circulation loop including a heat exchanger through which a heat transfer gas is circulated from said distillation chamber, through said heat exchanger and back into said chamber, said circulating heat transfer gas passing through said chamber and contacting said carbonaceous char to transfer heat from the char to the heat transfer gas and thereby cool the char, and said circulating heat transfer gas passing through said heat exchanger to remove heat from the heat transfer gas and thereby cool the heat transfer gas.
