Abstract:
The present disclosure provides a process for effectively separating and removing by-products (light gas, C5-C6 hydrocarbon oil fraction, polyethylbenzene) contained in a substantial amount in addition to ethylbenzene as a target compound in an alkylation reaction product of a fluidized catalytic cracking off-gas to prepare ethylbenzene having high purity, and process economical efficiency may be secured by utilizing the polyethylbenzene as an absorbent or gasoline fraction, without requiring a transalkylation reaction for further producing ethylbenzene from polyethylbenzene.

Claim (Index 12):
The method of  claim 1 , wherein a residue after recovering the ethylbenzene in the ethylbenzene recovery column is discharged into an ethylbenzene recovery column bottom stream, and at least a portion of the ethylbenzene recovery column bottom stream is fed to the absorption tower as the absorbent.
