Abstract
The present invention relates to a process for the production of ethylbenzene from dilute ethylene streams, especially from mixtures of ethane and ethylene where such mixture is the offgas from a refinery operation, such as a fluid catalytic cracking (FCC) operation and wherein the unreacted ethane from the alkylation reactor is dehydrogenated to produce ethylene which is recycled into the original dilute ethylene stream.
