Separation of commercially valuable chemicals from tire-derived pyrolytic oils

摘要

Commercially valuable chemicals are separated from tire- derived pyrolytic oils by subjecting the pyrolytic oils to a fractional distillation at a temperature of up to about 204° C. under atmospheric pressure to isolate at least one commercially valuable chemical selected from the group consisting of paraffins, naphthenes, olefins and aromatics. Particularly valuable chemicals which can be extracted from tire-derived pyrolytic oils are benzene, toluene, xylene, styrene and dl-limonene.
