초록 ▼

An improved process and apparatus for the destructive distillation or pyrolysis of rubber, such as used rubber tires, to produce liquid and gaseous hydrocarbons and a solid carbonaceous char. A heat transfer gas circulating in a circulation loop is used to cool the hot char produced in the distillation chamber of a distillation oven, the circulation loop having some means for removing the heat transferred to the heat transfer gas from the hot char. In one embodiment, two distillation ovens are operated in off-set, batchwise distillation cycles. The distillation cycles in the two ovens are coordinated so that a fresh charge of rubber feed is introduced into the distillation chamber of one of the ovens as the distillation of rubber in the other oven is concluded. The heat transfer gas is then circulated through both distillation chambers of the two ovens such that heat is transferred from the hot char produced in one oven at the end of a cycle to the heat transfer gas, and then transferred from the gas to the cold rubber feed introduced into the distillation chamber of the other oven at the beginning of a cycle to preheat the rubber feed. An effective means for determining the distillation end point and a pressurized distillation oven door seal are also provided.

1. A batch process for the destructive distillation of rubber to produce hydrocarbon and solid carbonaceous char, the process comprising:heating a rubber charge in a distillation chamber in the substantial absence of oxygen to a temperature sufficient to pyrolyze the rubber, distill a substantially oxygen-free process gas comprising hydrocarbon vapor from the rubber and produce a solid carbonaceous char, heat for the distillation of the rubber being supplied by a radiant heating assembly within said chamber; cooling the process gas to partially condense the hydrocarbon vapor and produce a liquid fraction comprising hydrocarbon and a remaining gaseous fraction; discontinuing heating of the rubber charge; and cooling the carbonaceous char by contacting the carbonaceous char with a heat transfer gas comprised of substantially oxygen-free process gas to transfer heat from the char to the heat transfer gas and thereby cool the char, the heat transfer gas circulating in a circulation loop, said circulation loop comprising cooling means for removing the heat transferred to the heat transfer gas from the char by indirect heat transfer.
