Pyrolysis Process and Products

摘要

A pyrolysis device and process to convert a carbonaceous feedstock to a carbon solid and pyrolysis gas, and processes for refining the resulting carbon solid and pyrolysis gases. The pyrolysis process may include introducing a carbonaceous feedstock into a pyrolysis processor having a vertical rotary tray processor, heating the feedstock to a temperature above about 790° F., removing a carbon material from a bottom of the pyrolysis processor, and removing a pyrolysis gas from a top of the pyrolysis processor.

主权项

1. A method of pyrolysis to recover the carbon black in steel-free tire shreds, comprising:
introducing a carbonaceous feedstock consisting of steel-free tire shreds into a top portion of a vertical tray pyrolysis processor maintained at a generally neutral pressure, the processor comprising a plurality of trays and a heating element; heating the tire shreds to a temperature above about 790° F. to pyrolyze the tire shreds and form a plurality of solids and pyrolysis gasses; circulating the pyrolysis gasses in the pyrolysis processor; moving the solids from trays positioned higher in the pyrolysis processor to trays positioned lower in the pyrolysis processor, the solids contacting the pyrolysis gasses during the moving; removing carbon black from a bottom portion of the pyrolysis processor; and removing pyrolysis gasses from a top portion of the pyrolysis processor.
