ABSTRACT:
Ethylene and maximum benzene are co-produced via a combination process involving (1) thermal cracking, or pyrolysis, (2) aromatic hydrocarbon separation, or extraction, and, (3) dealkylation of alkyl-substituted aromatics to yield additional benzene. Unconverted feed paraffins are recycled to thermal cracking for additional ethylene and benzene production.
