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 13):
The method of  claim 6 , wherein a residue after recovering the ethylbenzene in the ethylbenzene recovery column is discharged into an ethylbenzene recovery column bottom stream, the ethylbenzene recovery column bottom stream is mixed with the absorbent recovery column bottom stream, and at least a portion of a heavy oil fraction stream in which the ethylbenzene recovery column bottom stream and the absorbent recovery column bottom stream are mixed is fed to the absorption tower as the absorbent.
