Process and apparatus for multistage thermal treatment of rubber waste, in particular scrap tires |
摘要 |
A process for multistage thermal treatment of rubber waste, in particular scrap tires, is proposed. The process comprises several steps of transferring a product granulate of rubber waste into three different sequencing heating zones of a reactor (10). In the heating zones (11a, 11b, 11c) the product granulate is heated at a first temperature between 100° to 200° C., preferably 150° to 180° C., then at a second temperature between 200° to 350° C. and at a third temperature between 300° to 600° C. The temperature is maintained until such time that no further oil is emitted within the respective heating zone. As a final step, the product granulate is removed from the reactor (10) and the desirable solid materials are separated. |

1. Process for multistage thermal treatment of rubber waste to produce carbon black comprising the steps of:
transferring a product granulate of the rubber waste from a supply into a reactor; heating the product granulate for a time period of between 2 to 4 hours at a first temperature between 100° to 200° C. in a first heating zone of the reactor until light oils emitting from the product granulate at temperatures between 100° to 200° C. are no longer emitted; transferring the product granulate from the first heating zone to a second heating zone in the reactor; heating the product granulate for a time period of between 2 to 4 hours at a second temperature between 200° to 300° C. in the second heating zone of the reactor until medium heavy oils emitting from the product granulate at temperatures between 200° to 300° C. are no longer emitted; transferring the product granulate from the second heating zone to a third heating zone in the reactor; heating the product granulate for a time period of between 2 to 4 hours at a third temperature between 300° to 600° C. in the third heating zone until heavy oils emitting from the product granulate at temperatures between 300° to 600° C. are no longer emitted; and removing the product granulate from the reactor and separating the desirable solid materials, wherein each of the heating steps is carried out within a low pressure environment of about 20 to 50 mbar in each heating zone. |
